Also get the test case from git (in you $HOME again):
Then use a fixed and stable version of specfem3D_globe (the one of October 31, 2017
for example, see https://github.com/geodynamics/specfem3d_globe/commits/master)

cd $HOME/specfem3d_globe

you will also find environment and submission scripts templates for several machines

## Launch specfem
The launch procedure is simplified by the `run_mesher_solver.bash` script included
with tests cases. You just have to simlink some parameters file and binaries before launching it:
**-> You will find in the specfem folder of ueabs repository the file "compile.sh" which is an compilation script template for several machines (different architectures : KNL, SKL, Haswell and GPU)**

You can use or be inspired by the submission script template in the job_script folder using the appropriate job submission command :
- qsub for pbs job,
- sbatch for slurm job,
- ccc_msub for irene job (wrapper),
- llsubmit for LoadLeveler job.
sbatch -J specfem -N 1 --ntasks=24 --cpus-per-task=2 -t 01:00:0 --mem=150GB run_mesher_solver.bash
```
## Gather results
......@@ -118,8 +121,8 @@ The relevant metric for this benchmark is time for the solver. Using slurm, it i
easy to gather as each `mpirun` or `srun` is interpreted as a step wich is already
timed. So the command line `sacct -j <job_id>` allows you to catch the metric.
Otherwise edit the `run_mesher_solver.bash` script and add the time command befor the
call to the solver.
Or you can find more precise timing info at the end of this output file : specfem3d_globe/OUTPUT_FILES/output_solver.txt
