Hardware:

Processor: Core 2 Quad 2.40 Ghz
RAM:       4 Gb
scratch:   120 Gb

Queue name:

nanYar.quad

Nodes availables:

There are right now 43 nodes available.

Kind of jobs:

By now, please send ONLY Gaussian's jobs.

Ask for:

NPROC=4


Submit calculations[edit]

At the moment, to submit calculations:

  • Add %nproc=4 in the Gaussian input file, if you use the submision script qs it will be added automatically to the in.in file.
  • To sumbit the job, type:
 qs [number_of_quads]  q  job_type  script_to_submit_or_input_file.in

e.g.

qs 2 q g03 Test.in

O_O! #@"! So, don't use Jaguar in the Quadcores. 


In the future, for more slots ask for multiple of 4.
