How to access the server

Access to YARCC is through the login node: physlogin.york.ac.uk.

Instructions for accessing YARCC from Linux, Windows and MACs are here: /wiki/spaces/RHPC/pages/25107458.

The login servers are to be used for program/application development and job submission only. Please do not run your programs on the login nodes for long periods of time - this is what the cluster is for!YARCC

IMPORTANT - Run your jobs from the /scratch filesystem.

In order to have reliable job execution and the best performance, you have to run your jobs from the /scratch filestore:

A sub-directory in /scratch, with your username as the directory name, has been created for you to use.

For example "/scratch/abc123". This directory is accessible from all nodes.

This is not optional, running your jobs from your home directory will result in your jobs being killed when started by the grid engine.


Your directory in /scratch
abc123@login0$ cd /scratch
abc123@login0$ who am i
abc123  pts/6        2015-04-21 09:08 (mypc.york.ac.uk)
abc123@login0$ ls

abc123@login0$ cd abc123
abc123@login0$ pwd
/scratch/abc123

*****************************
*** DO ALL YORK WORK HERE ***
*****************************

Please do all you work in your /scratch directory.

Note:

If you still get this error and you are sure you are submitting your job from the scratch directory, you may have edited your file on a Windows PC and transferred it to /scratch.

Editing text files on Windows has the bad effect of inserting additional characters into the file. After you have transferred the file to the login server, use the following command to remove these characters:

dos2unix <job-script>

We do not recommend that you edit your files on a Windows PC and transfer them to the cluster.
