I want to test a test as it will be executed. Can someone please tell me
how do I run a "cuda" test SNES ex56 exactly?
This is the test in ex56.c
test:
suffix: cuda
nsize: 2
requires: cuda
args: -cel
Thanks,
Mark

Has anyone run the entire test harness under a batch system? Is this
possible, does it require specific commands that should be documented in the
users manual?
Thanks

Yes, it is possible. I have run the test harness on cori submitting the
following script
#!/bin/bash -l
#SBATCH -N 1 #Use 1 nodes
#SBATCH -t 02:00:00 #Set time limit
#SBATCH -p regular #Submit to the regular 'partition'
#SBATCH -C knl,quad,cache #Use
This assumes that the compilers are all available and working on the
compute nodes, correct?
Thanks

Do the compilers work on the compute nodes of theta?

yes - thats how I did the spack/xsdk build on theta.
However - it took a very long time - and this interfers with the
queues and their time limits.
I was told [later] that mostlikely 'the 'make -j200' job was being
scheduled on a single core of the theta node - and I needed to change
some setting
I recall that we had a discussion on this before. It would be great if we could
separate the 'compile' stage and the 'run' stage so that we can compile the
test on login node and then run it on compute node. Is this feature already in
the test harness system or what we are going to have?

It would be possible to build all the executables in advance (okay when
using shared libs).
Make running on a single core wouldn't be a big deal (on a normal
kernel) as long as the MPIEXEC interfaced with the resource manager
(SLURM) to distribute (blocking and returning output).
