So Platform announced Platform Cluster Manager (PCM) this week.

It is basically OCS rebranded. Why?

1. better name to tell people what the software is for (PCM is alot clearer than OCS)

2. Align with rest of Platform's naming convention

3. More catchy :-)

We are planning on Kusu2 and PCM2 new features and capabilities now, and I believe it will give cluster admins a much more usable tool to address the whole lifecycle of ...

Another story on Red Hat HPC and Kusu

Red Hat chases Redmond with HPC play • The Register


But to say that Red Hat chases Redmond is not exactly right. It is more of Redmond chasing after the Linux HPC market.

I have seen the new Windows HPC Server 2008 and I must say it is very nicely done with good integration of management and monitoring tools. But what they have delivered in Windows HPC Server 2008 is what the Linux HPC market has since 2006; ...

The next step is to propagate the config on the nodes (compute-00-00, compute-00-01, compute-00-02). The installer is not part of the server pool (will copy the fs-conf file on clients only later).

We want a rc script to start the server, so just edit the one provided in the example directory:

--------------------------------------------------------
cp examples/pvfs2-server.rc examples/pvfs2-server
-------------------------------------------------------- ...

Let's play with PVFS (Parallel Virtual File System), and perform a manual install on an OCS 5 cluster. If we want to build a kit, then we should be able to recompile the code (+dependencies), understand the configuration, and of course how to test it, right ?

Two versions of are available; I will use version 2. The homepage is here:

Parallel Virtual File System, Version 2


So, let's start with the latest and greatest version: PVFS-2.7.1

Partitioning is important in Kusu for the following reasons:

1. On the master node, the disks need to be correctly partitioned, so that repositories can be created on the disk before handing over to the distro's auto-installation mechanism.
2. On the compute node, partitioning needs to take place unattended, according to a predefined schema in the database, with options to preserve certain types of partitions as well.

Over the next few blog entries, I will describe the approach taken ...
