CyberShake Workflow Framework

This page provides documentation on the workflow framework that we use to execute CyberShake.

As of 2018, we use shock.usc.edu as our workflow submit host for CyberShake, but this setup could be replicated on any machine.

Overview

Overview of workflow framework

The workflow framework consists of three phases:

Create. In this phase, we use the Pegasus API to create an "abstract description" of the workflow, so named because it does not have the specific paths or runtime configuration information for any system. It is a general description of the tasks to execute in the workflow, the input and output files, and the dependencies between them. This description is called a DAX and is in XML format.
Plan. In this phase, we use the Pegasus planner to take our abstract description and convert it into a "concrete description" for execution on one or more specific computational resources. At this stage, paths to executables and specific configuration information, such as the correct certificate to use, what account to charge, etc. are added into the workflow. This description is called a DAG and consists of multiple files in a format expected by HTCondor.
Run. In this phase, we use Pegasus to hand our DAG off to HTCondor, which supervises the execution of the workflow. HTCondor maintains a queue of jobs. Jobs with all their dependencies satisfied are eligible to run and are sent to their execution system.

We will go into each phase in more detail below.

Software Dependencies

Before attempting to create and execute a workflow, the following software dependencies must be satisfied.

Workflow Submit Host

In addition to Java 1.7+, we require the following software packages on the workflow submission host:

Pegasus-WMS

Purpose: We use Pegasus to create our workflow description and plan it for execution with HTCondor. Pegasus also provides a number of other features, such as automatically adding transfer jobs, wrapping jobs in kickstart for runtime statistics, using monitord to populate a database with metrics, and registering output files in a catalog.

How to obtain: You can download the latest version (binaries) from https://pegasus.isi.edu/downloads/, or clone the git repository at https://github.com/pegasus-isi/pegasus . Usually we clone the repo, as with some regularity we need new features implemented and tested. We are currently running 4.7.3dev on shock, but you should install the latest version.

Special installation instructions: Follow the instructions to build from source - it's straightforward. On shock, we install Pegasus into /opt/pegasus, and update the default link to point to our preferred version.

HTCondor

Purpose: HTCondor performs the actual execution of the workflow. Part of Condor, DAGMan, maintains a queue and keeps track of job dependencies, submitting jobs to the appropriate resource when it's time for them to run.

How to obtain: HTCondor is available at https://research.cs.wisc.edu/htcondor/downloads/, but installing from a repo is the preferred approach. We are currently running 8.4.8 on shock. You should install the 'Current Stable Release'.

Special installation instructions: We've been asking the system administrator to install it in shared space.

HTCondor has some configuration information which must be setup correctly. On shock, the two configuration files are stored at /etc/condor/condor_config and /etc/condor/condor_config.local.

In condor_config, make the following changes:

LOCAL_CONFIG_FILE = /path/to/condor_config.local
ALLOW_READ = *
ALLOW_WRITE should be set to IPs or hostnames of systems which are allowed to add nodes to the Condor pool. For example, on shock it is currently ALLOW_WRITE = *.ccs.ornl.gov, *.usc.edu
CONDOR_IDS = uid.gid of 'Condor' user
All the MAX_*_LOG entries should be set to something fairly large. On shock we use 100000000.
DAEMON_LIST = MASTER, SCHEDD, COLLECTOR, NEGOTIATOR
HIGHPORT and LOWPORT should be set to define the port range Condor is allowed to use
DELEGATE_JOB_GSI_CREDENTIALS=False ; when set to True, Condor sometimes picked up the wrong proxy for file transfers.

In condor_config.local, make the following changes:

NETWORK_INTERFACE = <machine ip>
DAGMAN_MAX_SUBMITS_PER_INTERVAL = 80
DAGMAN_SUBMIT_DELAY = 1
DAGMAN_LOG_ON_NFS_IS_ERROR = False
START_LOCAL_UNIVERSE = TotalLocalJobsRunning<80
START_SCHEDULER_UNIVERSE = TotalSchedulerJobsRunning<200
JOB_START_COUNT = 50
JOB_START_DELAY = 1
MAX_PENDING_STARTD_CONTACTS = 80
SCHEDD_INTERVAL = 120
RESERVED_SWAP = 500
CONDOR_HOST = <workflow management host>
LOG_ON_NFS_IS_ERROR = False
DAEMON_LIST = $(DAEMON_LIST) STARTD
NUM_CPUS = 50
START = True
SUSPEND = False
CONTINUE = True
PREEMPT = False
KILL = False
REMOTE_GAHP = /path/to/rvgahp_client
GRIDMANAGER_MAX_SUBMITTED_JOBS_PER_RESOURCE = 100, /tmp/cybershk.titan.sock, 30
GRIDMANAGER_MAX_PENDING_SUBMITS_PER_RESOURCE = 20
GRIDMANAGER_MAX_JOBMANAGERS_PER_RESOURCE = 30

Globus Toolkit

Purpose: The Globus Toolkit provides tools for job submission, file transfer, and management of certificates and proxies.

How to obtain: You can download it from http://toolkit.globus.org/toolkit/downloads/latest-stable/ .

Special installation instructions: Configuration files are located in install_dir/etc/*.conf. You should review them, especially the certificate-related configuration, and make sure that they are correct.

The Globus Toolkit reached end-of-life in January 2018, so it's not clear that it will be needed going forward. Currently, it is installed on shock at /usr/local/globus .

rvGAHP

To enable rvGAHP submission for systems which don't support remote authentication using proxies (currently Titan), you should configure rvGAHP on the submission host as described here: https://github.com/juve/rvgahp .

Remote Resource

Pegasus-WMS

On the remote resource, only the Pegasus-worker packages are technically required, but I recommend installing all of Pegasus anyway. This may also require installing Ant. Typically, we install Pegasus to <CyberShake home>/utils/pegasus.

GRAM submission

To support GRAM submission, the Globus Toolkit (http://toolkit.globus.org/toolkit/) needs to be installed on the remote system. It's already installed at Titan and Blue Waters. Since the toolkit reached end-of-life in January 2018, there is some uncertainty as to what we will move to.

rvGAHP submission

For rvGAHP submission - our approach for systems which do not permit the use of proxies for remote authentication - you should follow the instructions at https://github.com/juve/rvgahp to set up rvGAHP correctly.

shock.usc.edu configuration

On shock, the primary directory for managing workflows is the 'runs' directory, /home/scec-02/cybershk/runs . This is where the create/plan/run scripts, the workflow configuration files, the catalogs, and the workflows themselves are located. Note that because of the way the Java paths in the scripts are set up, if you invoke them from a different directory they may not be able to find the DAX generator.

Create

Overview of create stage

In the creation stage, we invoke a wrapper script which calls the DAX Generator, which creates the DAX file for a CyberShake workflow.

At creation, we decide which workflow we want to run -- SGT only, post-processing only, or both ('integrated'). The reason for this option is that often we want to run the SGT and post-processing workflows in different places. For example, we might want to run the SGT workflow on Titan because of the large number of GPUs, and then the post-processing on Blue Waters because of its XE nodes. If you create an integrated workflow, both the SGT and post-processing parts will run on the same machine. (This is because of the way that we've set up the planning scripts; this could be changed in the future if needed).

Wrapper Scripts

Four wrapper scripts are available, depending on which kind of workflow you are creating.

On shock, all of these wrapper scripts are installed in /home/scec-02/cybershk/runs. Each creates a directory, <site name>_<workflow type>_dax/run_<run_id>, where all the workflow files are located for that run.

create_sgt_dax.sh

Purpose: To create the DAX files for an SGT-only workflow.

Detailed description: create_sgt_dax.sh takes the command-line arguments and, by querying the database determines a Run ID to assign to the run. The entry corresponding to this run in the database is either updated or created. This run ID is then added to the file <site short name>_SGT_dax/run_table.txt. It then compiles the DAX Generator (in case any changes have been made) and runs it with the correct command-line arguments, creating the DAXes. Next, a directory, <site short name>_SGT_dax/run_<run id>, is created, and the DAX files are moved into that directory. Finally, the run in the database is edited to reflect that creation is complete.

Needs to be changed if:

New velocity models are added. The wrapper encodes a mapping between a string and the velocity model ID in lines 129-152, and a new entry must be added for a new model.
New science parameters need to be tracked. Currently the site name, ERF id, SGT variation id, rupture variation scenario id, velocity model id, frequency, and source frequency are used. If new parameters are important, they would need to be captured, included in the run_table file, and passed to the Run Manager (which would also need to be edited to include it).
Arguments to the DAX Generator change.

DAX Generator

The DAX Generator consists of multiple complex Java classes. It supports a large number of arguments, enabling the user to select the CyberShake science parameters (site, erf, velocity model, rupture variation scenario id, frequency, spacing, minimum vs cutoff) and the technical parameters (which post-processing code to select, which SGT code, etc.) to perform the run with. Different entry classes support creating just an SGT workflow, just a post-processing (+ data product creation) workflow, or both combined into an integrated workflow.

A detailed overview of the DAX Generator is available here: CyberShake DAX Generator.

Plan

The next stage of workflow preparation is called 'planning'. In this stage, the DAX generated in the creation step is converted into Condor-formatted DAG files. As part of this process, the job and file names in the DAX are converted into specific paths in the DAG. Additionally, Pegasus wraps all executables in kickstart, which gathers runtime information on the job, and also adds other jobs such as registration, directory creation, and staging.

Catalogs

Before you can successfully plan a workflow, you need to have catalogs, which explain to Pegasus how to resolve the logical names into physical ones, and also sets up any site-specific configuration information. There are three catalogs to consider:

Transformation Catalog
Site Catalog
Replica Catalog

Transformation Catalog (TC)

Full documentation on the TC is available in the Pegasus documentation. Here we will provide a brief overview.

For every combination of executable you want to run and system you want to run it on, there needs to be an entry in the TC. This makes sense; somehow, Pegasus needs to be able to replace the logical name in the DAX with physical paths. We use a text file for the TC. On shock, the TC is located in /home/scec-02/cybershk/runs/config/tc.txt .

A sample entry in the TC looks like this:

tr scec::UCVMMesh:1.0 {
        site bluewaters {
                pfn "/projects/sciteam/baln/CyberShake/software/UCVM/single_exe.py"
                arch "x86_64"
                os "LINUX"
                type "INSTALLED"
                profile globus "host_count" "32"
                profile globus "count" "1024"
                profile globus "maxwalltime" "45"
                profile globus "jobtype" "single"
                profile globus "nodetype" "xe"
                profile globus "project" "baln"
                profile pegasus "cores" "1024"
        }
        site titan {
                pfn "/lustre/atlas/proj-shared/geo112/CyberShake/software/UCVM/single_exe.py"
                arch "x86_64"
                os "LINUX"
                type "INSTALLED"
                profile globus "hostcount" "96"
                profile globus "count" "1536"
                profile globus "maxwalltime" "60"
                profile globus "jobtype" "single"
                profile globus "account" "GEO112"
                profile pegasus "cores" "1536"
        }
}

The name of the job is in the format namespace::jobname:version . These values must match the values specified when the DAX is created, or Pegasus won't know they're the same job.

The 'pfn', 'arch', 'os', and 'type' entries are required. Only the 'pfn' (short for Physical File Name) entry should change between systems. The 'profile globus' entries provide a way to give system-specific parameters. For example, you can specify the number of nodes ('count'), the number of cores ('hostcount'), the maximum runtime ('maxwalltime'), and the project to bill. 'jobtype single' means that the entry point - the Python script single_exe.py - will be run serially from the command line. This is what we want, as we call aprun ourselves from the Python script.

If an entry is missing, or the file is not in the correct format, Pegasus will throw an error during planning.

In addition to the CyberShake jobs, a few Pegasus jobs also have entries in the TC, such as pegasus::mpiexec and pegasus::transfer. This provides a way to specify custom wrappers or configuration for these internal Pegasus jobs.

Site Catalog (SC)

Full documentation of the Site Catalog is available in the Pegasus documentation.

The Site Catalog contains site-specific information in XML format. For example, the URLs of the GridFTP endpoints or GRAM servers, paths to the appropriate X509 certificate, where on disk workflows should be executed, and the paths to Pegasus.

Here are sample Site Catalog entries for Blue Waters (GRAM) and Titan (rvGAHP):

<site handle="bluewaters" arch="x86_64" os="LINUX" osrelease="" osversion="" glibc="">
        <grid  type="gt5" contact="h2ologin4.ncsa.illinois.edu:2119/jobmanager-fork" scheduler="Fork" jobtype="auxillary" os="LINUX" arch="x86"/>
        <grid  type="gt5" contact="h2ologin4.ncsa.illinois.edu:2119/jobmanager-pbs" scheduler="PBS" jobtype="compute" os="LINUX" arch="x86"/>

                <file-server operation="all" url="gsiftp://gridftp.ccs.ornl.gov/lustre/atlas/proj-shared/geo112/CyberShake/data">
                </file-server>
        </directory>
        <profile namespace="pegasus" key="style">glite</profile>
        <profile namespace="pegasus" key="change.dir">true</profile>
        <profile namespace="condor" key="grid_resource">batch pbs /tmp/cybershk.titan.sock</profile>
        <profile namespace="pegasus" key="queue">batch</profile>
        <profile namespace="condor" key="batch_queue">batch</profile>
        <profile namespace="env" key="PEGASUS_HOME" >/lustre/atlas/proj-shared/geo112/CyberShake/utils/pegasus/default-service</profile>

        <profile namespace="globus" key="hostcount">1</profile>
        <profile namespace="globus" key="maxwalltime">30</profile>
</site>

For both systems, we specify directory paths + GridFTP servers for shared-scratch and shared-storage, which are expected by Pegasus. We also provides paths to PEGASUS_HOME and the X509_USER_PROXY. On Blue Waters, we also provide URLs for the GRAM endpoints, and specify X509_CERT_DIR, the path to use for grid certificates. On Titan, we add some special configuration keys to enable rvGAHP, and also provide defaults for hostcount and maxwalltime (these would be overwritten by the TC). The SC uses the same 'namespace key value' idea as the TC.

Every computational resource you wish to run on, and every site listed in the TC, must have an entry in the SC. There are several versions of the SC on shock, but the current one is at /home/scec-02/cybershk/runs/config/sites.xml.full .

Replica Catalog (RC)

Full documentation available at the Pegasus documentation.

The Replica Catalog keeps track of where input and output data files which are used in Pegasus workflows (the ones you specify in the DAX generator) are located. This is done via mappings between logical file names (LFN) and physical file names (PFN). We give each entry a pool=<remote system> entry also, so that Pegasus knows which system things are located on. The string used for the remote system must match the string used in the TC and SC.

For example, an entry in the RC might be:

e36_rv6_0_0.txt gsiftp://bw-gridftp.ncsa.illinois.edu/projects/sciteam/baln/CyberShake/ruptures/Ruptures_erf36/0/0/0_0.txt site="bluewaters"
e36_rv6_0_0.txt gsiftp://gridftp.ccs.ornl.gov/lustre/atlas/proj-shared/geo112/CyberShake/ruptures/Ruptures_erf36/0/0/0_0.txt site="titan"

This is an entry for one of the rupture geometry files, 'e36_rv6_0_0.txt'. There are two locations for this file, one on Blue Waters and one on Titan. When a workflow is planned, Pegasus takes the LFNs specified in the DAX, the system you want to run on, and goes to the RC to determine where the input file is located. If the file is located on the execution system, Pegasus will make a symlink; if not, it will stage the file in. This means that every external input file (files which are not generated as part of the workflow) must have at least 1 entry in the RC, or you'll get an error.

The tool for interacting with the RC is pegasus-rc-client, part of the Pegasus software. It supports lookups, insertions, and deletions. Typically, we produce an file in the following format:

<lfn> <pfn> pool=<remote system name>

This file can then be given to pegasus-rc-client for bulk additions. This is required every time we create a new set of rupture geometries, with a new ERF ID and rupture variation scenario ID, and individual SRFs if we are not generating them in memory. This should be done for each execution system to avoid extra file transfers.

The RC is also responsible for outputs. To simplify telling Pegasus where files should be transferred, we use regular expressions to express where the output files should go. A file in the format <lfn> <pfn> pool=<system> regex="true" is used to specify the outputs for the different file types without needing to include each output file explicitly. Full details about this file format can be found in the Pegasus documentation here.

Here are the current contents of the output regex (at /home/scec-02/cybershk/runs/config/rc.regex.output):

"(\\w+)_f[xyz]_(\\d+)\\.sgt.*" gsiftp://bw-gridftp.ncsa.illinois.edu:2811/scratch/sciteam/scottcal/SGT_Storage/[1]/[0] pool="bluewaters" regex="true"

The first entry is for SGTs, then follow the LF entries, then the BB entries. [0] refers to the entire string matched, and [1], [2], etc. to the match in the first set of parentheses, the 2nd set, and so on. That way we can preserve the site, source, and rupture information in the output file name.

Pegasus knows to use this file because we point to it in the properties file, described next.

Properties file

The properties file is a key input to the planning stage. It specifies how to access the SC, TC, and RC, and also provides other information used in creating and wrapping the workflow tasks. Full documentation is available on the Pegasus site.

Currently we use a few different properties files depending on which workflow is being generated and on which system. All properties files are on shock on /home/scec-02/cybershk/runs/config.

properties.full is the default.
properties.bluewaters is used for integrated, post-processing, and stochastic workflows on Blue Waters.
properties.sgt is used for the SGT workflows.

All the properties files share some entries. Some of these entries may have been deprecated; these properties have been accumulated since the beginning of CyberShake using Pegasus.

pegasus.local.env=X509_USER_PROXY=/tmp/x509up_u33527 pegasus.catalog.replica.cache.asrc=true pegasus.transfer.inter.thirdparty.sites = hpc,mercury,shock,sdsc,abe,ranger,stampede,bluewaters

Needs to be changed if:

New sites are added (need to be added to the pegasus.transfer.*.sites arguments)
RC, TC, SC catalog locations are changed
Different grid certificates need to be used

Scripts

As in the Create stage, we run bash scripts which wrap the pegasus-plan command.

SGT workflow

Purpose: To plan an SGT-only workflow.

Detailed description: plan_sgt.sh takes command-line arguments with the DAX to plan and the execution system, and

Needs to be changed if:

Arguments to the DAX Generator change.

 -nd,--no-duration             Omit duration calculations.
 -nls,--no-low-site-response   Omit site response calculation for
                               low-frequency seismograms.
 -nr,--no-rotd                 Omit RotD calculations.

Run Manager

The Run Manager is a collection of python scripts which wrap database commands used to query or modify the status of a CyberShake run. They are used both in create/plan/run scripts, and also in the Run Manager website. The Run Manager also enforces a state transition table, documented here. These scripts are rarely called directly, but are used extensively in the create/plan/run scripts. These scripts include:

create_run.py: Create a new run in the database given a series of science parameters.
create_stoch_run.py: Similar, but creates a new run with stochastic parameters, which requires tracking of different things.
edit_run.py: Modify the status or comment field for an existing run.
find_run.py: Search the database for a preexisting run, given a series of science parameters.
find_stoch_run.py: Finds a preexisting run with stochastic components.
valid_run.py: Checks to see if a run is in a valid state before applying a state transition.

The RunManager helper scripts are at http://source.usc.edu/svn/cybershake/import/trunk/runs/runmanager , with the shared core at http://source.usc.edu/svn/cybershake/import/trunk/RunManager/ .

The RunManager scripts would need to be edited if:

The database parameters change (Config.py, line 6)
A new compute site is added (Config.py, add to HOST_LIST in line 15)
A new user is added (Config.py, add to USER_LIST in line 20)
New science parameters are added to the database, which are used to differentiate between runs. Changes would need to be made to create_run.py, find_run.py, and RunManager.py.

On shock, these scripts are installed in /home/scec-02/cybershk/runs/runmanager .
