OSCAR is difficult at best to install on PS3's I have been working with it now
for about 5 months on PS3's running YDL5.0 and I was successful in setting it
up but there were a lot of initial problems. The Cell architecture of the PS3
is unforgiving. I would agree with Joe on his statements of if you are already
to a point of application development I would not backtrack.

I don't know the specific answer to your question (does OSCAR support YDL6.2 on
PPC64), but OSCAR will just end up duplicating a lot of the effort you've
already put in. If you're looking for a more automated way to do much of what
you've already done, then you may want to reinstall using OSCAR, but if you are
to a point where you just want to write some MPI code, there's no reason to
back-track and start again with a new toolkit, IMHO.

Subject: [Oscar-users] Using OSCAR
I have a rather basic question. I have been tasked to create an HPC from a
group of Playstation 3 (PS3). The PS3 are PPC64 and running YDL 6.2. The
server (head) is a Dell quad-core i686 running Fedora Core 12. I have
configured this Beowulf cluster using static IP addresses for each node machine
while the server has a dual Ethernet card - one to the outside world and the
other to the cluster using another static IP address. I have loaded OpenMPI on
all of the machines. I have disabled the built-in firewalls on all the
machines (the server is behind a corporate firewall, so no worries about being
attacked from the outside) and have set up NFS on them also. I believed that I
was ready to start programming an MPI application, but was doing a bit of
research and came across an article about OSCAR. I am mildly familiar with
OSCAR, but am not an expert. I'm wondering if anyone has tried to install/use
OSCAR on a Fedora Core 12 head and YDL 6.2 Nodes? I don't have a lot of time
to experiment on whether it will work or not and don't want to turn this into a
research project. Anyone have any opinions on whether the current release of
OSCAR will be compatible with my cluster? Thanks.
