====== How to use the PACE cluster ====== FIXME This document is a mere stub of what it ought to be. The Georgia Tech Public Access Cluster Environment (PACE) is a cluster of number-crunching Linux boxes. The Center for Nonlinear Science owns a few of the machines in this cluster with 4 to 8 CPUs per node. PACE is useful for running lots of long, CPU-intensive calculations and for running parallel programs with MPI. The work process is roughly this: you log on to PACE, submit a process to the CNS job queue, wait until it's finished, and then look at the results. This usually involves transferring files back and forth between your local computer and the PACE cluster using scp (the Unix secure copy utility). It ain't always pretty but it keeps your laptop from melting. ====== PACE documentation ====== [[http://www.pace.gatech.edu/facilities/pacecc/starting.php|The official PACE documentation page from OIT.]] {{:gtspring2009:pc.png|}} temptation to Balkanization is irresistible, but there is a [[http://www.cns.gatech.edu/CNS-only/PACE.html|CNS PACE homepage]] on the svn wwwcns repository, so please enter general (not channelflow specific) PACE documentation there. --- //[[predrag.cvitanovic@physics.gatech.edu|Predrag Cvitanovic]] 2009-02-22 16:41// {{:gtspring2009:gibson.png?24}} You might be the only person on the planet with enough goodwill, patience, and CNS permissions to document via svn checkout, editing html, checkin, and recheckout as www on zero. Maybe we can get some contributions by lowering the overhead with dokuwiki editing. ====== PACE login ====== {{:gtspring2009:pc.png|}} Your PACE login ID is your GTID, but I have to create an account for each user, because CNS gets charged for PACE usage. --- //[[predrag.cvitanovic@physics.gatech.edu|Predrag Cvitanovic]] 2009-02-22 16:46// ====== ssh tunneling ====== The denizens of CNS have written [[http://www.cns.gatech.edu/CNS-only/index.html|a bunch of shell scripts]] that simplify the process of logging in to the CNS machines and the PACE cluster from outside Georgia Tech. You will probably want to install these and figure out how to use them. Ask oldtimers you do not know the CNS webpages password. ====== install channelflow ====== Install channelflow on the PACE cluster. This should be straightforward. Follow the [[docs:install]] directions. ====== submit a job to the queue ====== ====== view the results ======
