Most applications will run on either Broadwell or Skylake nodes, and performance differences are expected to be small compared to job waiting times. Therefore we recommend that you do not select a specific node type for your jobs. If it is necessary, use <code>--constraint=skylake</code> or <code>--constraint=broadwell</code>. See [[Running_jobs#Specifying_a_CPU_architecture|Specifying a CPU architecture]]. | Most applications will run on either Broadwell or Skylake nodes, and performance differences are expected to be small compared to job waiting times.

Effective since '''April 17, 2019''', the jobs running in the <code>/home</code> filesystem are no longer allowed on cedar. The policy is put in place to reduce the load on that file system and improve the responsiveness for interactive work. If you get the following message: '''you are not permitted to submit jobs from that directory''', when submitting a job, transfer the files from that directory either to your <code>/project</code> or <code>/scratch</code> directories and submit the job from there. | Effective since '''April 17, 2019''', the jobs running in the <code>/home</code> filesystem are no longer allowed on cedar.
