All SLAC users can run parallel jobs on the shared "bullet" shared cluster. It has 5024 cores using the following configuration. The hardware is configured as follows:
- RHEL6 64bit OS x86 nodes
- 2.2GHz Sandy Bridge CPUs
- 16 cores per node
- 64GB RAM per node
- QDR (40Gb) Infiniband for MPI comms
- 10Gb ethernet for SLAC networking
| Queue | min. # cores | max. # cores | default runtime | max. runtime |
|---|---|---|---|---|
| bulletmpi | 8 | 512 | 15 mins | 7 days |
| bulletmpi-large | 513 | 2048 | 15 mins | 1 day |
There are 2 mpi queues for parallel computing at SLAC, bulletmpi and bulletmpi-large. They are available to anyone with a SLAC unix account, but we monitor these queues a bit more closely and you will need to send email to unix-admin to request access to these queues. Jobs submitted to these queues use some of the same batch hosts that are in use by the general farm.
