The Ohio Supercomputer Center (OSC) is experiencing an email delivery problem with several types of messages from MyOSC. 

OSC has conducted thorough validations to ensure the integrity of our backup data for the /fs/ess filesystem and are beginning full-scan backups of the home directories.

Request access

Users who would like to use the Ascend cluster will need to request access.  This is because of the particulars of the Ascend environment, which includes its size, GPUs, and scheduling policies.


Access to Ascend is done on a case by case basis because:

  • All nodes on Ascend are with 4 GPUs, and therefore it favors GPU work instead of CPU-only work
  • It is a smaller machine than Pitzer and Owens, and thus has limited space for users

Good Ascend Workload Characteristics

Those interested in using Ascend should check that their work is well suited for it by using the following list.  Ideal workloads will exhibit one or more of the following characteristics:

  • Needs access to Ascend specific hardware (GPUs, or AMD)
  • Software:
    • Supports GPUs
    • Takes advantage of:
      • Long vector length
      • Higher core count
      • Improved memory bandwidth

Applying for Access

PIs of groups that would like to be considered for Ascend access should send the following in a email to OSC Help:

  • Name
  • Username
  • Project code (group)
  • Software/packages used on Ascend
  • Evidence of workload being well suited for Ascend
