Frequently asked questions from our users

—Nicole Wolter

Dear SDSC Consulting,
Often when a user tries to submit a job on a resource an error such as the following is returned:

tg-login1 /users/uxXXXXX> qsub run.script 
Your job will not run Invalid #@account_no 'som202' for queue 'dque',
valid accounts for user <username> are:
No valid accounts found

Answer:
This error message could mean that the account has run out of allocated SU's(service units) on the given resource, or the user may have entered an incorrect account. To check personal usage and all available accounts on a given system, a user can run either the command reslist, which will show local usage, or tgusage which will give a more complete view of all allocations for a given user name. A user can also visit theTeragrid web page and check their account usage on their personal Teragrid portal page. Teragrid portal can be accessed by logging in from: http://www.teragrid.org/

Dear SDSC Consulting,
When an allocation is created, users will be added initially at the PI's request. However often labs change users and resource needs. How can a PI or a user with a pre-existing account add and remove users from all resources easily by accessing the Teragrid portal page.
Answer:
Users with pre-existing accounts can add or remove users and accounts of the existing allocations at their personal Teragrid portal page. A user can access and submit the forms under "My Teragrid" by clicking on the "Add/Remove User" tab. User's personal contact information, PI's contact information, and Teragrid Project Number will be required to complete the form. The PI will be contacted with all requests and will personally need to create new accounts to add to the existing allocations.

Did you know ..?

that Home directories should not be used for Batch jobs
Home directories are good places for login scripts and source files.Because it is NFS-mounted (slower than GPFS), this area is not suitable for storing large amounts of output from batch jobs. Increased home directory quotas for non-I/O intensive work and CVSROOT area for storing CVS directory trees are provided upon request. Users can request the CVSROOT area by emailing consult@sdsc.edu.- Larry Diegel
