by Tom Parker There are at least five ways to submit Crays jobs. Here is a brief rundown on these methods.
QsubQsub allows you to submit a batch job interactively when you are logged into a Cray. For example, to submit your job, you can login to ouray and type: qsub my.job.script For more information when you are on a Cray, type:
man qsub
IRJEThe Internet Remote Job Entry (IRJE) system is generally for users outside the Boulder UCAR-owned buildings. It allows you to submit Cray jobs from your workstation and also allows you to use the Mass Storage System (MSS). You need to register to use IRJE.Once you are set up, here is sample job submission to ouray: ftp irje.ucar.eduFor more information on IRJE, see the IRJE User's Guide.
MIGSThe MASnet/Internet Gateway Server (MIGS) is generally for people inside the Boulder UCAR-owned buildings. It allows you to submit Cray jobs from your own workstation. You can also use the MSS, etc. You need to register to use MIGS and get it set up for your particular workstation. Once you are set up, here is sample job submission to ouray: nrnet oujob my.job.scriptFor more information on MIGS, see the MIGS User's Guide.
XxjobIf you use meeker.ucar.edu, the SCD front-end computer, you can use the xxjob suite of commands to submit Cray jobs. Substitute xx with the first two letters of the Cray name -- for instance, ou for ouray, or an for antero. For example, to submit a job to ouray, type:
oujob my.job.scriptFor more information on xxjob on meeker, type:
man xxjob
CqsubCqsub can be used to cross-submit from one machine to another. It is a tad inconvenient because you may need to set an environment variable. For example, to submit a job to ouray, type:
setenv NQS_SERVER ourayThis method is available on the Crays, ute, and meeker. For more information on cqsub, see the SCD UserDoc "NQE available on meeker."
