We are working on ucvm2mesh-mpi software to confirm it works in ucvmc
Contents
UCVM2mesh-mpi Questions
- Locate ucvm2mesh-mpi documentation (look for configuration file)
- We determined there are some manual pages of ucvm2mesh and ucvm2mesh-mpi and posted example configuration files on ucvmc wiki
- Do the ucvm2mesh and ucvm2mesh-mpi produce the same results?
- We have a test case that shows the outputs are identical
- What direction is the X axis and Y axis (confirm x is horizontal before rotation)
- We have test cases that show the origin is expected to be the south west corner, and increasing X is in roughly east, assuming no rotation.
- Confirm that positive rotation is counter clockwise
- We have a test case that shows this is true
- Describe differences in output format mesh file versus grid file
- The grid file is the x and y values, and the associated lat/lon values. The media file is one of four formats
- Describe differences in output format for ijk-12, ijk-16, ijk-32 and SORD
- The formats define number of bytes. Two of the formats include Qp and Qs values. ijk-32 includes the ijk values in the file
- How can we set origin at center of region (rather than at lower left point)
Installation and test process
Notes on the installation and test process are here:
small scale ucvm queries
- Define small scale sample problem
- 20 km x 10km x 10k volume
- 1km spacing
- with rotation
- without rotation
- with ucvm2mesh
- with ucvm2mesh-mpi
Example Usage
ucvm2mesh.conf file
# List of CVMs to query ucvmlist=cvmh,bbp1d # UCVM conf file ucvmconf=/auto/scec-00/maechlin/t1/conf/ucvm.conf # Gridding cell centered or vertex gridtype=CENTER # Spacing of cells spacing=2000.0 # Projection proj=+proj=utm +datum=WGS84 +zone=11 rot=-40.0 x0=-122.3 y0=34.7835 z0=0.0 # Number of cells along each dim nx=384 ny=248 nz=25 # Partitioning of grid among processors px=2 py=2 pz=5 # Vs/Vp minimum vp_min=0 vs_min=0 # Mesh and grid files, format meshfile=/auto/scec-00/maechlin/ucvm_mpi/mesh_cvmhbbp1d_ijk12_2000m.media gridfile=/auto/scec-00/maechlin/ucvm_mpi/mesh_cvmhbbp1d_ijk12_2000m.grid meshtype=IJK-12 # Location of scratch dir scratch=/scratch
ucvm2mesh pbs file
-bash-4.2$ more *.pbs #!/bin/bash # # This is the pbs script ucvm2mesh # #PBS -l nodes=4:ppn=5 #PBS -l walltime=00:10:00 #PBS -m ae #PBS -M maechlin@usc.edu ##PBS -q main #PBS -o $PBS_JOBID.out #PBS -e $PBS_JOBID.err cd $PBS_O_WORKDIR np=$(cat $PBS_NODEFILE | wc -l) cat $PBS_NODEFILE mpirun -np $np -machinefile $PBS_NODEFILE /auto/scec-00/maechlin/t1/bin/ucvm2mesh-mpi -f /auto/scec-00/maechlin/ucvm_mpi/ucvm2mesh_2 0cores.conf #mv /scratch/maechlin/mesh_cvmh_ijk12_2000m.media $PBS_O_WORKDIR/mesh_cvmh_ijk12_200m.media #mv /scratch/maechlin/mesh_cvmh_ijk12_2000m.grid $PBS_O_WORKDIR/mesh_cvmh_ijk12_200m.grid exit
Dumpgrid.py Utility
- dump_grid.py utility reads in grid file and dumps the i j values, and the lat/lon values
./dumpgrid.py mesh_bbp1d_ijk12_2000m.grid 384 248
produces
380, 247 : -112.506316, 33.825386 381, 247 : -112.490418, 33.813224 382, 247 : -112.474526, 33.801059 383, 247 : -112.458637, 33.788893
