+ | |||
+ | <pre> | ||
+ | |||
+ | I wanted to provide an update on my investigation of the velocity model differences Mei found. | ||
+ | I dug into s3171. These are the values from the CyberShake mesh: | ||
+ | |||
+ | Depth Vs | ||
+ | -0.8 1178.842041 | ||

+ | -1.12 1535.679932 | ||
+ | -1.2 1575.72937 | ||
+ | |||
+ | |||
+ | So something weird is happening around 1 km depth. | ||
+ | |||
+ | I queried UCVM using ucvm_query and got similar results (Vs values in bold): | ||

Pre-study
goal: to validate the sw4 plot of sfcvm native hdf5 datafile via its gmg reader shows topography features at surface and yet
accessing UCVM's sfcvm is showing a chopped plot at Z=0
Frontier setup
modules :
module load cray-python module unload PrgEnv-cray module load PrgEnv-gnu gcc module load libtool/2.4.6module load Core/24.07 module load openblas/0.3.26

#!/bin/bash # hn=`hostname -d` ppwd=`pwd` export MY_TOP=$ppwd/scratch export TOP_UCVM_TARGET=$MY_TOP/TARGET_UCVM_SFCVM export UCVM_SRC_PATH=$TOP_UCVM_TARGET/UCVM export UCVM_INSTALL_PATH=$TOP_UCVM_TARGET/ucvm_install rm -rf $TOP_UCVM_TARGET mkdir $TOP_UCVM_TARGET cd $TOP_UCVM_TARGET git clone https://github.com/SCECcode/ucvm.git -b withSFCVM UCVM cd $UCVM_SRC_PATH/largefiles ./get_largefiles.py -m sfcvm,cca,cvmsi cd $UCVM_SRC_PATH/largefiles; ./stage_largefiles.py cd $UCVM_SRC_PATH ./ucvm_setup.py -d -a -p $UCVM_INSTALL_PATH &> ucvm_setup_install.log echo "..EXITING.." exit
SPECIAL NOTE 1:
on Frontier, the first time ucvm_setup.py call seems to fail when configure is called via script. If rerun by hand, It actually goes through.
1) extract the configure command from config.log and run it by hand 2) at UCVM top level, call
make clean; make; make install
3) make sure ucvm_env.sh is setup properly
./ucvm_setup.py -a -d -r -p $UCVM_INSTALL_PATH
4) source $UCVM_INSTALL_PATH/conf/uvcm_env.sh
SPECIAL NOTE 2:
for sw4, hdf5 needs to be enabled with parallel option,
1) cd $UCVM_SRC_PATH/work/lib/hdf5 2) extract the configure command from config.log, and rerun it with --enable-parallel 3) and then call
make clean; make; make install;

compile sw4 by

making sfcvm mesh in sfile format using sw4
building sw4-ucvm_clone is just the same as sw4-stock but it is alittle ad-hoc and so just assume it is done and the sfcvm_mesh.sfile is here..
ccs/home/mei/proj-geo156/ucvm/sw4/sfcvm.output/sfcvm_mesh.sfile
the sfcvm.txt used for generate this sfcvm_mesh.sfile,

making image slice from sfcvm_mesh.sfile
the input file ,sw4_sfcvm.sw4input, needs to update the path links,

mei@discovery1:/project/scec_608/mei/sw4-stock$ git checkout v3.0 Note: switching to 'v3.0'. You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by switching back to a branch. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -c with the switch command. Example: git switch -c <new-branch-name> Or undo this operation with: git switch - Turn off this advice by setting config variable advice.detachedHead to false HEAD is now at 13e6d431 Merge pull request #195 from geodynamics/developer

Scott's study of s3171
I wanted to provide an update on my investigation of the velocity model differences Mei found. I dug into s3171. These are the values from the CyberShake mesh: Depth Vs -0.8 1178.842041 -0.88 1220.528809 -0.96 2603.321777 -1.04 2661.860596 -1.12 1535.679932 -1.2 1575.72937 So something weird is happening around 1 km depth.
