When you log into Sauron, you are on its head-node. You should not use this node for anything other than to submit your jobs. Please make very careful note of this point. Failure to do so could result in the head-node crashing. This can have very bad consequences, e.g., loss of data, jobs crashing. Follow the process outlined below for proper and harmonious functioning of the cluster.
Note that the filesystem on Sauron is different from the filesystem of the general computational facilities computers. Copy your source (and other files) over from your machine to Sauron using scp.
Example 1. A scp session
[itctestcluster] ~ > scp wol.c sdutta@sauron:~/bin/ wol.c 100% 5701 5.6KB/s 00:00 [itctestcluster] ~ >
Once your files are on Sauron, you can compile and submit your jobs using the queueing system.
Please note that resources in Sauron are restricted and available on a honour system. Disk space is not unlimited. Please remove archival data from Sauron to make way for newer data. Additionally, data on Sauron is not backed up, so store data there at your own risk. Further, although the job queue isn't restricted, jobs running in excess of 24 hours and occupying more than 20 nodes need approval from at least one ITC faculty member.
