Computational Hardware

There are two ways to access BCG computational hosts. First, you can log into one of the open compute servers, nebula-1 through nebula-9. The nebula machines should only be used for interactive jobs. Note that you must be on the local network to log directly into any of these machines.

Secondly, background or batch jobs can be run either on your own desktop machine or scheduled with condor.

Quasars

People in the Medical Informatics group can also log directly into these hosts (which also run condor jobs). Currently available (as of August 2014):

  • quasar-18 through quasar-25
  • quasar-27 through quasar-28
  • quasar-30 through quasar-52

Old quasars are retired and new ones added regularly.

Very High Memory Servers

We have two very high memory hosts, mastodon-1 and mastodon-2, with 500G and 40 cores a piece. If you have jobs that have high memory requirements, please send a request to sysreq@biostat.wisc.edu with a very brief description of your need, and we will give you access to these machines.

Dedicated Condor Hosts

We have a 40-machine pool of linux computers which do condor only, pulsar-1 through pulsar-40. No one has direct access to these machines.

Other Hosts

Your PI may have dedicated hosts available just for their lab.
