Is anyone creating a cloud based on Centos yet?

Ubuntu seems to be quite active there:

So there still has no CENTOS HPC solution provided yet, has upstreamer disclosed the source?

ftp://ftp.redhat.com/pub/redhat/linux/beta/RHHPC still not accessable.

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.

If the centos community wish to obtain the srpms directly from us, I can provide them as rhhpc srpms are obtained from us.

As expressed before to the community here and to KB, we are willing to help build and contribute to the CentOS HPC SIG.

Yes, please do provide the srpms

thanks

Also, we are going to start preparing ours to work with RHEL 5.4 when it is out in the coming months. Can the community wait till our 5.4 compatible version is ready. This may coincide with the Centos 5.4 release.

The last time we had this conversation there was an issue with 'your srpms' are really not the 'red hat' srpms. Has this situation changed ?

Any progress on this?

KB,

Our srpms[1] are given to Red Hat and thus are being rebuild by them. EPEL srpms are not given because RH takes them directly from their own epel builds.

Till date, RH has not released the srpms. Community request is certainly helpful here.

If you download the srpm from rhn and compare against ours, it is not the same. The md5sum will not be the same because the srpms are generated by their build system using ours. Each srpm has a redhat buildhost, signed by them, etc. However, the content is the same.

If it's a centos policy to strictly use rh srpms, then we would be better off asking RH to release them to the community. Kusu/PCM is GPL v2.

-Liming [1] PCM RHHPC edition srpms, since PCM has various editions.
