UCVM Command Reference (v15.10.0)

UCVM Software Collection

The UCVM software is a software framework that builds on top of several existing scientific software packages, including CVM-H, CVM-S4, and the USGS Bay Area Model. The UCVM installation process involves first compiling the individual CVM programs, and then compiling and installed the UCVM framework.

The UCVM installation process involves two code directory trees, the src tree, and the bin tree. UCVM source codes and models are collected in the src directory tree. When UCVM is built, it is installed into a separate directory location, called the bin directory tree. Once UCVM is correctly built and installed, user configure their computing environment to point to the bin directory. All supported UCVM commands are contained in the UCVM bin tree.

Command Reference Conventions

We base our instructions and documentation assuming a standard open source software environment.

Default installation operating system is a 2015 or later Linux distribution with Python 2.7, multiple packages, gnu c and fortran compilers.

Default user shell is a bash shell and our documentation.

We will call the bin directory tree $UCVM_HOME_DIR in the command descriptions below:

UCVM commands are located in the bin tree, in several directories including $UCVM_HOME_DIR/bin, /tests, /utilities, /scripts

Command line examples are shown as:

%ucvm_command

basin_query

UCVM(1) BSD General Commands Manual UCVM(1)

NAME 

    basin_query

SYNOPSIS 

    basin_query [-h] [-f config-file] [-m model] [-v vs-threshold]

[-p usermap] [-z zmin,zmax] [-d max-depth] [-i interval] < file.in

DESCRIPTION 

    The command basin_query allows you to retrieve the depth at which
    vs-threshold is first crossed. By default, vs-threshold is set to be
    1000m/s, but that can easily be changed.

    Common Paramters

    -f       Location of the UCVM configuration file. Typically, this is

../conf/ucvm.conf. 

    -m       Model to query. Usually model is either cvms, cvmh, cvmsi, or

cencal. 

    -v       Vs threshold to use. By default this is 1000m/s, but other com-

mon values include 2500m/s and 3000m/s. 

    Less Used Parameters

    -p       Custom vs30 and elevation map location.

    -z       Custom depth range for GTL/crust interpolation.

    -d       Maximum depth, in meters, to search. Default is 15000m.

    -i       Interval, in meters, go go by when searching for the depth.

Default is 20m. So basin_query will get the Vs value at 0m, 20m, 40m, and so on.

EXAMPLE 

    basin_query -f ../conf/ucvm.conf -m cvms -v 2500

Input: -118 34 Ctrl-D

Output: -118.0000 34.0000 4780.000 4780.000

ucvm2etree-extract-MPI.txt

UCVM(1) BSD General Commands Manual UCVM(1)

NAME 

    ucvm2etree-extract-MPI

SYNOPSIS 

    ucvm2etree-extract-MPI [-h] -f config

DESCRIPTION 

    Notice: This command is intended to be run as a MPI job (e.g. mpirun
    ./ucvm-extract-MPI).  Please do not attempt to run it as a regular
    process.

    The command ucvm2etree-extract-MPI extracts components of an e-tree from
    the specifications in a given configuration file, config.

    Specifically, it divides the etree region into C columns for extraction.
    This is an embarrassingly parallel operation. A dispatcher (rank 0) farms
    out each column to a worker in a pool of N cores for extraction. Each
    worker queries UCVM for the points in its column and writes a flat-file
    formatted etree. After program execution, there are N sub-etree files,
    each locally unsorted. The extractor must be run on 2^Y + 1 cores where
    Y>0 and (2^Y) < C. The output flat file format is a list of octants(24
    byte addr, 16 byte key, 12 byte payload) in arbitrary Z-order.

    Since the number of points in a column depends on the minimum Vs values
    within that column, some columns will have high octant counts and others
    will have very low octant counts. Having sub-etrees that vary greatly in
    size is not optimal for the sorting operations that follow, so
    ucvm2etree-extract-MPI implements a simple octant balancing mechanism.
    When a worker has extracted more than X octants (the default 16M
    octants), it reports to the dispatcher that it cannot extract any more
    columns and terminates.  This strategy approximately balances the sub-
    etrees so that they may be loaded into memory by ucvm2etree-sort-MPI. In
    the case of very large extractions where the dispatcher reports that all
    workers have reported they are full yet columns remain to be extracted,
    increase the job size by a factor of 2 until there is room for all the
    columns.

    You would typically run this command, followed by ucvm2etree-sort-MPI and
    ucvm2etree-merge-MPI.

    -h       Displays the help message.

    -f       Uses configuration file, config.

ucvm2etree-merge-MPI

UCVM(1) BSD General Commands Manual UCVM(1)

NAME 

    ucvm2etree-merge-MPI

SYNOPSIS 

    ucvm2etree-merge-MPI [-h] -f config

DESCRIPTION 

    Notice: This command is intended to be run as a MPI job (e.g. mpirun
    ./ucvm-merge-MPI).  Please do not attempt to run it as a regular process.

    The command ucvm2etree-merge-MPI merges the sorted components of an e-
    tree from the ucvm2etree-sort-MPI command. It does so by reading in the
    specifications in a given configuration file, config.

    Specifically, it merges N locally sorted etrees in flat file format into
    a final, compacted etree. This is essentially a merge sort on the keys
    from the addresses read from the local files. The cores at the lowest
    level of the merge tree each read in octants from two flat files in pre-
    order, merge sort the two sets of addresses, then pass the locally sorted
    list of addresses to a parent node for additional merging. This proceeds
    until the points rise to rank 1 which has a completely sorted list of
    etree addresses. Rank 0 takes this sorted list and performs a transac-
    tional append on the final Etree.

    The merger must be run on 2^N cores. The program reads in input files
    that are in flat file format. In can output a merged Etree in either
    Etree format or flat file format. Although, due to space considerations,
    it strips the output flat file format to a pre-order list ot octants(16
    byte key, 12 byte payload). The missing addr field is redundant and can
    be regenerated from the key field.

    You would typically run this command after ucvm2etree-extract-MPI and
    ucvm2etree-merge-MPI.

    -h       Displays the help message.

    -f       Uses configuration file, config.

UCVM(1) BSD General Commands Manual UCVM(1)

NAME 

    ucvm2etree-sort-MPI

SYNOPSIS 

    ucvm2etree-sort-MPI [-h] -f config

DESCRIPTION 

    Notice: This command is intended to be run as a MPI job (e.g. mpirun
    ./ucvm-sort-MPI).	Please do not attempt to run it as a regular process.

    The command ucvm2etree-sort-MPI sorts the extracted components of an e-
    tree from the ucvm2etree-extract-MPI command. It does so by reading in
    the specifications in a given configuration file, config.

    Specifically, it sorts the sub-etrees produced by ucvm2etree-extract-MPI
    so that each file is in local pre-order (Z-order). Again, the is an
    embarrassingly parallel operation. Each rank in the job reads in one of
    the sub-etrees produced by the previous program, sorts the octants in Z-
    order, and writes the sorted octants to a new sub-etree.  The sorter must
    be run on 2^Y cores where Y>0. The worker pool must be large enough to
    allow each worker to load all the octants from its assigned file into
    memory. By default, this octant limit is 20M octants. If a rank reports
    that the size of the sub-etree exceeds memory capacity, the 20M buffer
    size constant may be increased if memory allows, or alternatively, cvmby-
    cols-extract-MPI may be rerun with a larger job size to reduce the number
    of octants per file.

    You would typically run this command after ucvm2etree-extract-MPI and
    before ucvm2etree-merge-MPI.

    -h       Displays the help message.

    -f       Uses configuration file, config.

UCVM(1) BSD General Commands Manual UCVM(1)

NAME 

    ucvm2etree

SYNOPSIS 

    ucvm2etree [-h] -f config

DESCRIPTION 

    The command ucvm2etree builds an e-tree from the specifications in a
    given configuration file, config.

    Note that this is the serial version of the command, meaning that it will
    only run on a single process. As such, building a large e-tree can be
    very slow. For large e-trees, we strongly recommend using
    ucvm2etree-extract-MPI, ucvm2etree-sort-MPI, and ucvm2etree-merge-MPI.

    -h       Displays the help message.

    -f       Uses configuration file, config.

ucvm2mesh-mpi

UCVM(1) BSD General Commands Manual UCVM(1)

NAME 

    ucvm2mesh-mpi

SYNOPSIS 

    ucvm2mesh-mpi [-h] -f config

DESCRIPTION 

    Notice: ucvm2mesh-mpi is meant to be run as a MPI job, not as a stand-
    alone executable.

    The command ucvm2mesh-mpi generates a mesh in either IJK-12, IJK-20,
    IJK-32, or SORD format. Unlike its serial version, ucvm2mesh this command
    can use multiple cores to generate the mesh.  It does so by reading in
    the specifications in a given configuration file, config.

    This mesh can then be used in forward 3D wave propagation simulation
    software such as AWP-ODC.

    -h       Displays the help message.

    -f       Uses configuration file, config.

EXAMPLE 

    mpirun -np [procs] ucvm2mesh-mpi -f ./ucvm2mesh_example.conf

    Where ucvm2mesh_example.conf is:

    # List of CVMs to query
    ucvmlist=cvmh

    ucvmconf=../conf/kraken/ucvm.conf

    # Gridding cell centered or vertex

ucvm_query

UCVM(1) BSD General Commands Manual UCVM(1)

NAME 

    ucvm_query

SYNOPSIS 

    ucvm_query [-h] [-f config] [-m model] [-c coordtype] [-p map] [-v]

[-z zmin,zmax]

DESCRIPTION 

    The command ucvm_query queries an installed velocity model to retreive
    its material properties at a particular latitude and longitude.

    Any set of crustal and GTL velocity models may be selected and queried in
    order of preference. Points may be queried by (lon,lat,dep) or
    (lon,lat,elev) and the coordinate conversions for a particular model are
    handled transparently.

    Common Paramters

    -h       Displays the help message.

    -f       Location of the configuration file, config, that tells the pro-

gram which velocity models are installed. 

    -m       A comma-separated list of models to query.

    Less Used Parameters

    -c       Z-coordinate mode. Geo-depth (default) is "gd", but queries can

also be done by elevation as specified by "ge". 

    -p       User-defined map of vs30 and elevation data.

    -v       Display model version information only.

    -z       Specifies depth range for gtl/crust interpolation.

EXAMPLE 

    ucvm_query -f ../conf/ucvm.conf -m cvms

    Input format is:

lon lat Z 

    Output format is:

lon lat Z surf vs30 crustal cr_vp cr_vs cr_rho gtl gtl_vp gtl_vs 

    gtl_rho cmb_algo cmb_vp cmb_vs cmb_rho

    If running in interactive mode, please use Ctrl-D to end the input.
