Cycle Servers

Occasionally, members may need access to resources that extend beyond the normal capabilities of their desktop systems. When this happens, we ask that members execute these jobs on one of our cycle servers.

These systems are accessible via ssh from any computer or laptop within the MSRI domain. Cycle servers have access to all of the same math software and Linux utilities standard on any of our desktop systems. Please note: While some of these cycle servers have 64-bit processors, our operating systems currently only support 32-bit instructions, with the exception of 'quinn', running 64-bit Debian Linux.

The table below lists all available servers and resource configurations.

Please contact a computing staff member if you have further questions or need help in using these systems.

* Data should be stored in members home directories, but members may temporarily create their own directory locally in the /usr/local/members/ directory so that the server need not continuously access files through the network. There currently is no limit on the amount of disk space that a member can use. We do, however, ask that if space requirements exceed 100 MB that you first consult with a member of the computing staff.

** All cycle servers are running 32-bit operating systems except quinn
