Running LEM code with MPI

#1

Hi guys!

I am trying to execute the LEM code with CG_GPU solver. Then I use the command:
srun -p nvidia_dev -N4 run_lem.sh
So I am doing a test to be executed with 4 nodes, but I could see that LEM execute the same process 4 times


Do LEM work with MPI? if so, What is the command line to execute in several nodes?
Do LEM code create a log file with the total execution time? I wold like to do a comparison with different solvers and nodes,

Thanks.

LEM does not run on MPI, please use a single node and a GPU. It’s shared memory parallel.

ok,

Do LEM code create a log file with the total execution time? I wold like to do a comparison the execution time with different solvers.

Thanks

Please look at the Stats table in the SQLite db. It has information on solver time and assembler time extracted from the analysis, at each time step. https://cb-geo.github.io/lem-doc/#/postprocessing/postprocessing
