This sets the working directory for the mpiexec process to start. You may also find the -wdir option for mpiexec helpful.

#Ubuntu batch script example serial#

All of the examples on this page use $TMPDIR, so please check the specific serial or parallel sections if you're unsure what to do.

The directory is created and cleaned up for you, so you can get rid of all mkdir /tmp/$USER and rmdir /tmp$USER lines in your script as well.

To use this feature, simply change references to /tmp/$USER (or whatever scheme you're using to create a temporary directory) to $TMPDIR.

This directory is cleaned up when the job exits.

In the past, this meant that you did something like this in the beginning of the batch script: $ mkdir /tmp/$USER Now Torque creates a uniquely named directory (/tmp/$PBS_JOBID) when a job starts and stores the path of this directory in the $TMPDIR environment variable. But please see the section on /v4scratch for another alternative. It is faster to do local file I/O and copy complete data files to and from $HOME at the beginning and the end of the job, rather than do I/O over the network ($HOME is network mounted on the compute nodes). Most jobs will want to create a temporary directory on the compute node's local disk to read and write data from.This will assure each user that they have all of /tmp for the duration of their job. CLUSTER POLICY: A program is run at the beginning of every job that clears /tmp.You can also provide any other msub arguments that you like. You'll need to provide an account number, walltime estimate, and the number of nodes you're requesting as you submit the job. At this point, you should be ready to submit your job.# Copy output files to your output folder # copy the binary and data files to a local directory This is a script that will run on the compute node an example that executes a fictional binary in serial is shown below. All jobs must be submitted with the account number you wish to charge against explicitly provided, so have that number handy. You must have a valid account number that you are allowed to charge against.Your keys files will be recreated automatically. If you suspect a problem with your keys and want to recreate them, rename your ssh directory (in case you have other keys you wish to save), log off, and log back in. If you choose not to enter one, just hit twice. ROCKS creates the keys files for you automatically when you first log in. Before you submit a job, you must have valid ssh keys.Connect to the v4 linux login node ( or ) using ssh.
