[Swift-devel] Swift impact Fwd: [beagle-users] login nodes

[Michael Wilde]

Ketan, we should test running Swift on Beagle *from* a job run under qsub -I and aprun.

Ie, put Swift itself on a compute node.  As usage gets heavier, we'll need to do this to avoid overtaxing the login hosts (and giving Swift a black eye from the Sysadmin team).  Same applies everywhere, notably on TeraGrid hosts.

We should document how to do this and add this mode to the test suite.

- Mike

This is a reminder that resource intensive commands should not be run on the login nodes. In fact in all but rare cases the only command that should be run on them is qsub or aprun. IF you need to do resource intensive tasks, you must use sandbox.beagle.ci.uchicago.edu. During the next maintenance period, we will most likely be renaming nodes to properly reflect there use and restrict access and resources on the PBS MOM nodes (currently the login nodes).
