Running jobs on the Grid - old

From Research IT

To start type :

'grid-proxy-init'   -Note the port number that is given here.

- you will be prompted for a passcode. This creates a temporary, short lived credential for use by your computations. [[1]] For more options you can type in grid-proxit-init -help

'grid-proxy-info' - This will give you addistional proxy information.

To send Jobs to a computer in the grid first start a personal gate keeper:

 'globus-personal-gatekeeper -start'

Now to run a job. There are different ways to do this, here are a couple of examples. You will need to have an executable program or command that you want to run.

Here is the 1st example. You need to create an RSL file [[2]]

globusrun -r "dell1.rit.albany.edu:<PORT_NUMBER>:/O=Grid/OU=GlobusTest/OU=simpleCA-dell2.rit.albany.edu/
OU=rit.albany.edu/CN=McKenzie Patrick D" -f uname_gram.rsl

where PORT_NUMBER is the port number generated by the command 'globus-personal-gatekeeper -start' here is an example .rsl file (this should all be in the .rsl file)

 &
 (jobtype = single)
 (executable = "command")
 (arguments = "name")
 (count = 2)
 (stdout = "name" )

-executable is the command to use example "/bin/ls" -arguments are arguments to the executable -stdout is the filename of the stdout -jobtype and count and still investigating there usage -globus assumes path in the home directory

The 2nd example is using: globus-job-run this command does not need a rsl file here is an example globus-job-run "dell1.rit.albany.edu:<PORT_NUMBER>:/O=Grid/OU=GlobusTest/OU=simpleCA-dell2.rit.albany.edu/OU=rit.albany.edu/CN=McKenzie Patrick D" /bin/ls

before logging out, kill the 'globus-personal-gatekeeper -start' process. you can find the process number by using ps.
