CnodeCount/CnodeErrCount so to point out there are cnodes in an error state on the block. Draining the block and having it reboot when all jobs are gone will clear up the cnodes in Software Failure.

for a long time after the SLURM job has been flushed from the system we don't have to worry about rebooting the block to sync the system.

is a convenience function in BSD and glibc that internally calls the equivalent of int masterfd = open("/dev/ptmx", flags); grantpt (masterfd); unlockpt (masterfd); int slavefd = open (slave, O_RDRW|O_NOCTTY); (in psuedocode) On Linux, with some combinations of glibc/kernel (in this case glibc-2.14/Linux-3.1), the equivalent of grantpt(3) was failing in slurmstepd with EPERM, because the allocated pty was getting root ownership instead of the user running the slurm job. From the POSIX description of grantpt: "The grantpt() function shall change the mode and ownership of the slave pseudo-terminal device... The user ID of the slave shall be set to the real UID of the calling process..." http://pubs.opengroup.org/onlinepubs/007904875/functions/grantpt.html This means that for POSIX-compliance, the real user id of slurmstepd must be the user executing the SLURM job at the time openpty(3) is called. Unfortunately, the real user id of slurmstepd at this point is still root, and only the effective uid is set to the user. This patch is a work-around that uses the (non-portable) setresuid(2) system call to reset the real and effective uids of the slurmstepd process to the job user, but keep the saved uid of root. Then after the openpty(3) call, the previous credentials are reestablished using the same call.

Fix for srun allocating running within existing allocation with --exclude option and --nnodes count small enough to remove more nodes. > salloc -N 8 salloc: Granted job allocation 1000008 > srun -N 2 -n 2 --exclude=tux3 hostname srun: error: Unable to create job step: Requested node configuration is not available Patch from Phil Eckert, LLNL.

Add logic to cache GPU file information (bitmap index mapping to device file number) in the slurmd daemon and transfer that information to the slurmstepd whenever a job step is initiated. This is needed to set the appropriate CUDA_VISIBLE_DEVICES environment variable value when the devices are not in strict numeric order (e.g. some GPUs are skipped). Based upon work by Nicolas Bigaouette.
