I believe the Chapel launcher passes through most/all environment variables to the srun/salloc command, but I might be wrong. Is there already a slurm environment variable that does what you want? (I'd be surprised if the account to be used is only available as a command line option...) Looking at the man page for salloc... does SALLOC_ACCOUNT do the trick? I've had some success using using SALLOC_PARTITION and the default gasnetrun_ibv launcher. > >Additionally, when I try to setup chapel to use slurm over ibv, I think >I’m getting linking issues for mpi calls. I'm trying to reproduce your set-up, but Chapel with GASNet over IBV doesn't necessarily need to use MPI at all. It looks like you're trying to build on a system with OpenMPI, so I tried with OpenMPI version 2.0. Is that the version you are using? Did GASNet report that the MPI conduit was enabled during configuration? Did it report that it found mpicc? You could try adjusting the GASNet configure command-line options in third-party/gasnet/Makefile or by trying e.g. cd third-party/gasnet/ make clobber cd ../.. make CHPL_GASNET_CFG_OPTIONS="--without-mpi-root --without-mpi-cc --disable-aligned-segments" to request that GASNet not try to use MPI. I tried reproducing on an IBV system with OpenMPI 2.0 but I didn't see the link error. I was using master rather than 1.13 though. I'm also a bit surprised that GASNet's mpi-spawner is linked with a program that's trying to use slurm-gasnetrun_ibv, but of course it might be doing that. Generally, try to set all of your environment variables, then make in the Chapel directory, and then build the test Chapel program.
