The following guidelines for the appropriate use of CARC computing systems must be followed by all users. These guidelines are meant to ensure the security of user accounts as well as equitable access to shared computing resources.
By accepting a CARC account, you agree that:
Failure to comply with these rules will result in account removal and possible disciplinary or legal action.
Poblano is a single “supernode” with 32 cores + 32 floating point units and large (256 GB RAM) memory. This machine was designed for special applications that require large RAM. Thus, being a single node, it does not utilize the PBS job queuing system. Instead, we use an informal "sign-up" process coordinated among the users themselves. If you wish to use the poblano system, please submit a help ticket, and we will arrange for you to meet with a systems staff member to discuss your specific application requirements and for poblano access.
If your application's memory requirements do not exceed 65 GB RAM/node, other CARC systems may be more appropriate for your work. See Systems for a list of CARC supercomputer machine specifications.
Users are provided with an initial default password in their new user packet. You should change your password the first time you login and periodically thereafter. If it is necessary for you to request a password change (for example, if you have forgotten your current password), your password will be set to this default. It is important that you keep this form in a secure place for future reference. If you do not have this form available, you will be required to wait until a duplicate can be prepared. CARC does NOT provide passwords by campus or U.S. mail, phone, fax, or electronic mail.
When running codes on CARC machines, users are expected to regularly monitor their jobs to ensure that they are not overburdening, misusing, or hanging the machine they are using. The qstat -an and qgrok commands provide useful information about node and processor utilization by the user's job(s). In extreme cases, if CARC systems staff notice a problem with your job, it may be terminated without notice.
