The Irma Cluster

Irma was the NGI production system where genomic data from the sequencing machines are pre-processed before they are delivered to the researcher. Irma was part of the SNIC-SENS project until it was succeeded by Miarka.

Irma provided 4000 cores in the form of 250 dual CPU (Intel Xeon E5-2630 v3 @ 2.40GHz) SuperMicro nodes with a default memory configuration of 256 Gigabyte.

Irma ran CentOS 7 as operating system.

Irma was put into production in March 2016 and lived until April 2022.
