This is the contribs dir for SLURM. SOURCE DISTRIBUTION HIERARCHY ----------------------------- Subdirectories contain the source-code for the various contributations for SLURM as their documentation. A quick description of the subdirectories of the SLURM contribs distribution follows: env_cache_builder.c [C program] This program will build an environment variable cache file for specific users or all users on the system. This can be used to prevent the aborting of jobs submitted by Moab using the srun/sbatch --get-user-env option. Build with "make -f /dev/null env_cache_builder" and execute as user root on the node where the moab daemon runs. perlapi/ [ Perl API to SLURM source ] API to SLURM using perl. Making available all SLURM command that exist in the SLURM proper API. sjstat [ Perl program] Lists attributes of jobs under SLURM control skilling.c [ C program ] This program can be used to order the hostnames in a 2+ dimensional architecture for use in the slurm.conf file. It is used to generate the Hilbert number based upon a node's physical location in the computer. Nodes close together in their Hilbert number will also be physically close in 2-D or 3-D space, so we can reduce the 2-D or 3-D job placement problem to a 1-D problem that SLURM can easily handle by defining the node names in the slurm.conf file in order of their Hilbert number. If the computer is not a perfect square or cube with power of two size, then collapse the node list maintaining the numeric order based upon the Hilbert number. time_login.c [ C program ] This program will report how long a pseudo-login will take for specific users or all users on the system. Users identified by this program will not have their environment properly set for jobs submitted through Moab. Build with "make -f /dev/null time_login" and execute as user root. torque/ [ Wrapper Scripts for Torque migration to SLURM ] Helpful scripts to make transition to SLURM easier from PBS or Torque. These scripts are easily updatable if there is functionality missing. make.slurm.patch [ Patch to "make" command for parallel build ] This patch will use SLURM to launch tasks across a job's current resource allocation. Depending upon the size of modules to be compiled, this may or may not improve performance. If most modules are thousands of lines long, the use of additional resources should more than compensate for the overhead of SLURM's task launch. Use with make's "-j" option within an existing SLURM allocation. Outside of a SLURM allocation, make's behavior will be unchanged. Designed for GNU make-3.81. mpich1.slurm.patch [ Patch to mpich1/p4 library for SLURM job task launch ] For SLURM based job initiations (from srun command), get the parameters from environment variables as needed. This allows for a truly parallel job launch using the existing "execer" mode of operation with slight modification. ptrace.patch [ Linux Kernel patch required to for TotalView use ] 0. This has been fixed on most recent Linux kernels. Older versions of Linux may need this patch support TotalView. 1. gdb and other tools cannot attach to a stopped process. The wait that follows the PTRACE_ATTACH will block indefinitely. 2. It is not possible to use PTRACE_DETACH to leave a process stopped, because ptrace ignores SIGSTOPs sent by the tracing process.
