RedHat HPC = Platform OCS (www.platform.com) + RHEL + kits
http://vglug.info/files/HPC_Webinar_1-15-09.pdf (mentions platform OCS)
http://www.redhat.com/docs/en-US/hpc/1.0/pdf/Installation_Guide.pdf
kits = a base kit, in this case RHEL and few self contained cluster-oriented
applications (i.e. openmpi, lava, ganglia)
"RedHat HPC" comes with the two DVDs. One DVD containing Platform OCS, second
DVD contains RHEL and a few (8-10) kits.
When installing "RedHat HPC", first you boot in Platform OCS (which itself is
based on RH), you go through some basic configuration, and then you are asked
for the kits. You insert the RHEL+kits disk, where it extracts the RHEL base
and various kits. Instruction's in RH Installation guide assumes you are
installing OCS on top of RH. I only did a fresh installed so I started with
OCS, and added RHEL as a kit.
-----
previously Platform OCS (version 4) was based on Rocks Linux, and old docs
might not be compatible.
currently Platform OCS (version 5) is based on open source Project Kusu
(http://www.hpccommunity.org/). Project Kusu seems to be now part of
www.platform.com
-----
now for Centos HPC.
go to http://www.hpccommunity.org (currently down on my end), go to project
kusu, and pick up the Centos installer, configured to work with Centos, (burn
iso image). This is the first disk, the equivalent of Platform OCS. Assuming
a new installation, and not an installation of kusu on top of centos. Boot
using Kusu disk. Go through the setup, and at some point you'll be asked to
install kits. Here, you insert the DVD containing Centos 5.3
Kusu comes with 2-3 kits, but installing new kits is not too difficult (see
kusu docs), and probably a good practice in case you have to install a
non-preconfigured kit, ie intel compiler.
----
Unfortunatelly, based on the forum activity hpccommunity.org doesn't seem to be
a very active community. Also hpccommunity.org was previously
http://osgdc.org/ (probably before merging with platform.ocs).
Another project which seems to have branched off, and share a base with kusu is
unicluster -> www.grid.org parent company univaud.com. Unfortunatelly, this
too is as active as kusu, but there is enough documentation to get it going.
-----
I hope this layering of applications, where RH bundles 3rd party applications
and then puts it under the RH hat, doesn't become the norm.
