Also add size specification of "%0" to not limit a field size. For example "sacct --format=%0ALL" to print everything.

we used cpus erroneously but now we use tasks. The cpus variable will be taken out in 2.6.

Modify slurmctld data structure locking to interleave read and write locks rather than always favor write locks over read locks.

Dear all, As quick fix, I have put together this script to help manage native and symmetric MPI runs within SLURM. It's a bit bare-bones currently but I needed to get it working quickly :) It does not provide tight integration between the scheduler and MPI daemons and requires a slot on the host, even when running fully on the MIC, so it's really far from an optimal solution but could be a stopgap. It's inspired by the TACC Stampede documentation. They seem to have a similar script in place. It's fairly simple, you provide the names of the MIC binary (with -m) and host binary (with -c). The host MPI/OpenMP parameters are given as usual and the Xeon Phi side parameters as environment variables (MIC_PPN, MIC_OMP_NUM_THREADS). Currently it supports only 1 card per host but extending it should be simple enough. Here are a couple of links to documentation: Our prototype cluster documentation: https://confluence.csc.fi/display/HPCproto/HPC+Prototypes#HPCPrototypes-XeonPhiDevelopment Presentation at the PRACE Spring School in Umeå earlier this week: https://www.hpc2n.umu.se/sites/default/files/1.03%20CSC%20Cluster%20Introduction.pdf Feel free to include this in the contribs -directory. It might need a bit of cleanup though and I don't know when I have the time to do this. I have also added support for TotalView debugger (provided it's installed and configured properly for Xeon Phi usage). Future ideas: For the native MIC client, I've been testing it out a bit and looking at ways to minimize the changes needed for support. The two major challenges seem to be in scheduling and affinity: I think it might be necessary to put it into a specific topology plugin, like the one for BG/Q, but it looks like a lot of work to do that. Best regards, Olli-Pekka
