CMAQ version 5.3.1 Compiler Test
Timing Information for CMAQv5.3.1 - Nov 2019
The Community Multiscale Air Quality (CMAQ) modeling system Version 5.3.1 (CMAQv5.3.1) has a planned release date of early December 2019.
The CMAS Center tested the CMAQ release package with the debug and optimized compiler option to compare with the EPA. All tests were conducted with the U.S. EPA SE52 12km domain July 11, 2011 test dataset. The code used in this testing was obtained from EPA's github account, as a pull request to my github account. https://github.com/lizadams/CMAQ/tree/patches2
I ran using 32 processors for the optimized version.
@ NPCOL = 8; @ NPROW = 4
I obtained Fahim's output from atmos and transfered the first day's output to /proj/ie/proj/CMAS/CMAQ/from_EPA/CMAQv531_2016_12SE1_output
Ran for 2 days, GCC OPT version ran successfully for both days.
NOTE: Obtained the following error on the 2nd day of the run using the INTEL compiler 205250 Nov 26 14:03 CTM_LOG_011.v53_intel_Bench_2016_12SE1_full_CONC_20160702

MPI_ABORT was invoked on rank 16 in communicator MPI_COMM_WORLD with errorcode 538976288.
NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes. You may or may not see output from other processes, depending on exactly when Open MPI kills them.

QA plots are generated on longleaf using the interactive queue
R script for comparing model output results from different compilers
- module load r/3.4.3
- setenv R_LIBS /nas/longleaf/home/lizadams/R/x86_64-pc-linux-gnu-library/3.4
- cd /proj/ie/proj/CMAS/CMAQ/CMAQ_v5.3.1_branch2/CMAQ_QA
If you are on the login node, your prompt will contain the login node id:
- [lizadams@longleaf-login2 ~]
Start an interactive queue (don't run on the login node), your environment variables and R module will be set up
- srun -p interact --pty /bin/csh
Your login prompt will be something like
- [lizadams@off03 CMAQ_QA]$
Edit, then Run the R script that compares model output
- R CMD BATCH plot_max_diff_compiler_sens_v5.3beta.R
Plotting the difference in values between the base (EPA debug) and sensitivity (UNC debug) cases at the column, row, layer of the maximum difference between the variables. | Compilation Testing Plots
