How do I run a Globus job on the TeraGrid?

These examples of simple Globus runs on the TeraGrid assume that you have an SSH key and a Globus certificate. For help, see Where are instructions for getting a certificate to run Globus jobs on the TeraGrid?

1. Log into the National Center for Supercomputing Applications (NCSA): % ssh tg-login1.ncsa.teragrid.org
2. Create a proxy: % grid-proxy-init Your identity: /C=US/O=National Center for Supercomputing Applications/CN=Your Name Enter GRID pass phrase for this identity: Creating proxy ................................................. Done Your proxy is valid until: Fri Dec 17 03:32:25 2004 /C=US/O=National Center for Supercomputing Applications/CN=Your Name/CN=proxy
3. Verify that the proxy works by authenticating to San Diego Supercomputer Center (SDSC) from NCSA: % globusrun -a -r tg-login.sdsc.teragrid.org GRAM Authentication test successful
4. Run a HelloWorld job at SDSC: % more helloworld.rsl & (executable=/bin/echo) (arguments="Hello World!") % globusrun -s -r tg-login.sdsc.teragrid.org -f /home/ncsa/agopu/tmp/helloworld.rsl
5. Run a printDate job to verify that an output file was created at SDSC: % more printDate.rsl & (executable=/bin/date) (stdout=remotePrintDate.out) % globusrun -s -r tg-login.sdsc.teragrid.org -f /home/ncsa/agopu/tmp/printDate.rsl % gsissh tg-login.sdsc.teragrid.org Welcome to the TeraGrid Itanium2 Linux Cluster ... ... Directory: /users/ux455224 Thu Dec 1613:28:05 PST 2004 /users/ux455224> ls -l remotePrintDate.out -rw------- 1 ux455224 tgu221 29 2004-12-16 13:27 remotePrintDate.out /users/ux455224> more remotePrintDate.out Thu Dec 16 13:27:38 PST 2004 /users/ux455224> logout Connection to tg-login.sdsc.teragrid.org closed.
6. On multiple sites, run a job that prints the hostname of the gatekeeper at each site: % more printHostname.rsl + ( & (resourceManagerContact="tg-login.sdsc.teragrid.org/jobmanager-fork") (executable=/bin/hostname) (arguments=-f) ) ( & (resourceManagerContact="gatekeeper.bigred.iu.teragrid.org") (executable=/bin/hostname) (arguments=-f) ) % globusrun -s -f /home/ncsa/agopu/tmp/printHostname.rsl tg-login.sdsc.teragrid.org gatekeeper.bigred.iu.teragrid.org
