DROP cluster
- Drop is:
- drop.astron.nl
- With 6 nodes at 8 cores each, DROP is designed for non-interactive queue-based parallel supercomputing.
- Drop is not:
- For anything that is interactive, uses less than 8 parallel cores per job, is not queue-able, or generally takes less than a few nights to run on your desktop, you had better use one of the stand-alone servers.
- Drop has only scratch storage. Move important data to a different server. Anything on /data/ can be deleted without notice.
- Kindly note that this cluster comes 'as is' with no support from IT, Joeri or Jason.
- The login node 'drop' is also the file server. Do not run jobs there, in for- or background.
- Come see Joeri for an account
- File systems
- /export/home/<user>
- RAID6, 20GB/user quota, nothing ever auto-deleted
- /data (crossmounted over all nodes) = RAID0, unlimited space
- RAID0, 5TB, no quotas
- heaviest users will have older data auto-deleted by semi-random script, so better clear it out yourself
- Login/master/fileserver node is “drop”, nodes are called c0 to c5
- Queueing implemented to balance loads. Only use queue, do not start processing on your own.
