Ferlin - a resource for users in the Stockholm region
Ferlin is a resource for users in the Stockholm region (i.e. KTH,SU,KI). Local users can apply for time on Ferlin using the application form.
Ferlin was recently upgraded to Ekman nodes. It is expected that Ferlin will be available using these replacement nodes until the summer of 2015 or until a replacement is available.
There are some practical effects to this upgrade:
- The CPUs have changed from Intel Harpertown 2.66GHz CPUs (E5430) to AMD Opteron 2.2 GHz CPUs (2374 HE)
- The amount of Ram per node has been increased from 8 GB to 16 GB
- The connection between the nodes is significantly faster with the addition of an infiniband connection
The upgrade has not affected the software environment or queue. For performance reasons it is probably best to recompile with options for the new cpus, but most programs should continue to work.
Ferlin is named after Swedish 20th Century poet Nils Ferlin and its two login nodes are called

Ferlin is a foundation Level System (FLS) i.e. intended for applications that are not dependent on a fast network.
