The MITgcm model is tested (compiled and run) in an automated fashion on a variety of different machines. The following is a summary of the MITgcm verification suite for the time period: 2026_10.

The machine naming scheme is:

Nickname Processor Type Operating System
"villon" Intel Haswell Ubuntu 18 LTS (x86_64)
"batsi" Intel Haswell Fedora 29 (x86_64)
"baudelaire" Intel Xeon Fedora 13 (x86_64)
"glacier" Intel CentOS 6 (x86_64)
"svante" Intel Xeon (Sandy Bridge) Fedora 24 (x86_64)
"engaging" Intel Xeon (Sandy Bridge) CentOS 6
"pleiades" SGI Altix XE cluster (Intel Xeon) Suse Linux
"archer" Cray XC30 Linux
"ollie" Cray CS400 CentOS
"stan" NEC SX-ACE Super-UX
"jaures" Intel Core i7-4900MQ Fedora 29 (x86_64)


The complete output for the verification runs can be found in the summary pages and the testing archives. The latest reports are:
