Has anyone any experience using Oscar 3 with xw4100 and d530s . These HP boxes have Broadcom netXtreme NICs built into the motherboards. We have a single xw4100 as the master and 7 of the d530s as slaves. I've been working with just 2 slaves while I get a hang of the cluster software. I can get the cards up if I build bcm5700 modules (from manufacturers src rpm) and ping between boxes. I've seen posts (http://sourceforge.net/mailarchive/forum.php?thread_id=4159660&forum_id=1364) that suggest I'll need to build a custom kernel if I want to use them with Oscar and copy an image to /tftpboot/kernel is this correct?
There's a kernel/ramdisk pair (used for network booting) that was made for the Dell 2650 machines w/ the BCM5700... maybe that will get you going?

As an interim I've been using Netgear GA320T NICs; these are found OK by Redhat 9 but I still fail at the test cluster stage. I get the following errors:
/home is not mounted.
SSH node to server fails,
PVM (via PBS) fails,
PBS test shell fails,
MPICH fails,
LAM/MPI fails
PBS HDFS also fails.
Sounds like some serious problems here... if the network, /home, or ssh is down, pretty much nothing else will work as far as tests. You might want to explore it manually to try and see where it's failing.

The rest of the install seems ok. Any ideas?
I'm also puzzled over the NTP. Our IT people will not allow us to connect our cluster to the network so no chances of a ntp server. Can I set up the master as a ntp server for the cluster?
