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.

of it's dimensions of length 3. There is a limitation in the IBM I/O subsystem that is problematic with multiple sub-blocks with a dimension of length 3, so we will disallow them to be able to be created. This mean you if you ask the system for an allocation of 12 c-nodes you will be given 16. If this is ever fix in BGQ you can remove this patch.
