I haven't written for a few days. I have tried a few things, with no success. These include
* Switching to OSCAR 5.2b2 and CentOS 5.2 for the compute nodes. * Turning off iptables entirely on the head node. * Using a boot CD instead of booting over the net. * Editing the image's modprobe.conf so the ethernet driver (igb) is loaded. I haven't yet tried UYOK because I'm not sure how to make a proper kernel that would be better than the stock one. It's not clear what needs to be changed. (One thing that's never been clear to me is whether CentOS 5.2 can handle the hardware on these new systems. The motherboards come from SuperMicro. The head node is an H8DGU-F and the compute nodes are H8QG6-F. All have Opteron 6100 CPUs and AMD chipsets.) I'm running out of ideas. At the bottom of the barrel there are a couple that would be pretty painful: * Wipe out everything on the head node and put CentOS 5.2 on it. I might get lynched by the developers who have already installed a lot of stuff. * Pull one of the compute nodes out of the rack and remove its InfiniBand card, just to see if it's the root of the problem. ------------------------------------------------------------------------------ The Palm PDK Hot Apps Program offers developers who use the Plug-In Development Kit to bring their C/C++ apps to Palm for a share of $1 Million in cash or HP Products.
