+The Physics and Astronomy Department (DIFA) hosts a parallel computing infrastructure directly accessible to its staff members. This infrastructure is made up of three different groups (or islands) of computing nodes with different hardware features and target usage:
-  *** BladeRunner**: a set of compute nodes targeted to low-parallelism jobs (with hostnames bl0-NN)
+  *** BladeRunner**: a set of compute nodes targeted to low-parallelism jobs (with hostnames bldNN)
-  *** Matrix**: a set of compute nodes targeted to massively parallel jobs (with hostnames mtx-NN)
+  *** Matrix**: a set of compute nodes targeted to massively parallel jobs (with hostnames mtxNN)
-The [[:oph:cluster:access]] to the infrastructure is provided by the frontend server, with static IP address 137.204.50.177, that can be used to connect and transfer data to the cluster using the standard protocols ssh, scp, rsync.
+  *** GPU**: a set of compute nodes with Graphic Processing Units besides standard CPUs (with hostnames gpuNN)
+For a more detailed description of the hardware features and access policies of the different groups of nodes see the [[oph:cluster:resources|Resources]] section.
