3.5 Linux Cpuset Support - Adaptive Computing

    http://docs.adaptivecomputing.com/torque/3-0-5/3.5linuxcpusets.php
    3.5 Linux Cpuset Support ... Cpusets gain CPUs and memory units by simply writing the unit number to files within the cpuset. 3.5.2 Cpuset Support. When started, pbs_mom will create an initial top-level cpuset at /dev/cpuset/torque. This cpuset contains all CPUs and memory of the host machine. If this "torqueset" already exists, it will be left ...

    When started, pbs_mom will create an initial top-level cpuset at /dev/cpuset/torque. This cpuset contains all CPUs and memory of the host machine. If this "torqueset" already exists, it will be left unchanged to allow the administrator to override the default behavior. All subsequent cpusets are created within the torqueset.

Linux Cpuset Support - Adaptive Computing

    Cpuset support will easily constrain the processes to not interfere with other jobs. Jobs on larger NUMA systems may see a performance boost if jobs can be intelligently assigned to specific CPUs. Jobs may perform better if striped across physical processors, or contained within the fewest number of …

RPMS for TORQUE with Nvidia GPU Support – justinpenney.com

    https://justinpenney.com/rpms-for-torque-with-nvidia-gpu-support/
    Getting TORQUE built into RPMs with GPU support was considerably more frustrating than I expected. I’m really not a fan of TORQUE as I seem to often run in to silly problems or serious limitations since pbs_sched is so simplistic that it’s really not the best fit for most users … but I still have to support it, so here goes.. First we need to install CUDA.

1279565 – Torque will not allocate more than 1 CPU in a cpuset

    https://bugzilla.redhat.com/show_bug.cgi?id=1279565
    Ok, I added "nodes=0" to the mom.layout file, and "num_node_boards=1 numa_board_str=4" to the node properties. PBS mom now starts and Maui recognizes the one node with 4 processors, however, cpuset is still not working correctly.

    Bug 1231148 - [Wishlist] Please build torque with numa-support and cpuset. Summary: [Wishlist] Please build torque with numa-support and cpuset ... By enabling cpuset, the scheduler can assign suitable CPUs (on the same system bus) to one job, avoiding costly cross-memory calls.

mpi - Torque + mpirun + resources allocation - Stack Overflow

    https://stackoverflow.com/questions/19714914/torque-mpirun-resources-allocation
    The OpenMPI project mentions Torque integration in its FAQs on building and running OpenMPI. Similarly, Torque doesn't actually restrict access to CPUs unless cpuset support is enabled. Again, this seems absent in most distro packages. This is why your OpenMPI app, when compiled without Torque integration, can hit all the cores without restriction.
