 ILRI's high-performance computing cluster is currently composed of four dedicated "compute" machines and four "storage" machines:
-  * **hpc**: main login node, "master" of the cluster
+  * **hpc**: main login node, "head" of the cluster
   * **compute05**, **compute06**: used for batch and interactive jobs like BLAST, structure, R, etc (compute05 and compute06 have the newest AMD EPYC CPUs)
   * **compute07**: used for high-memory jobs like genome assembly (mira, newbler, abyss, etc)
-  * **compute03**: fast CPUs, but few of them
-To get access to the cluster you should talk to Jean-Baka (he sits in BecA). Once you have access you should read up on [[Using SLURM|SLURM]] so you can learn how to submit jobs to the cluster.

 ===== Cluster Organization =====
-The cluster is arranged in a master/slave configuration; users log into HPC (the master) and use it as a "jumping off point" to the rest of the cluster. Here's a diagram of the topology. For each server, we mention the number of CPUs and the year it was commissioned:
