[Swift-user] question about xsede

[Michael Wilde]

Justin,

Blacklight is an SGI machine, and thus a more standard PBS machine to 
which the Cray-specific sites file settings do not apply.

It does seem to have a few quirks, though, as describe at:
   https://portal.xsede.org/psc-blacklight#running

In particular, the page above suggests using "-l ncpus=N" where N is the 
number of CPUS desired and a multiple of 16.  But by default Swift will 
generate "-l nodes=n" where n is the number of nodes.

So we'll need to either do some testing (once we get on the machine) or 
send you our best guess of the right sites settings and work with you to 
test them for us.

We'll look into this further and report back.

- Mike
