performance recommendations

1. Use Grid Engine to run jobs in parallel

   Grid Engine balances jobs across the cluster, so the jobs run more efficiently.

2. Avoid running more than 3 CPU-intensive jobs within your X2Go session

   X2Go servers have only 8 CPUs, and are used by many people. If you need to run jobs in parallel, use Grid Engine

3. Use only one server for both X2Go and secure shell (SSH) logins.

   Jobs started via secure shell run at low priority unless you log into the server where your X2Go session is running.

4. Improve Jupyter Notebook performance by using a local web browser to display the Jupyter notebook.

5. Email me

   If you continue to experience performance problems, please email support-neuro@berkeley.edu.

   Please include as much information as possible, e.g.

   • name of server, e.g. nx1
   • name of program/application
   • command line used to run program
   • nature of problem, e.g. slow screen updates, analysis takes longer to complete, etc
   • error message
