Hello Michael,

Yes, I think both LAM/MPI and MPICH work with OpenSSI, although I wasn't directly involved with this testing effort. IIUC, there's not much that OpenSSI does that would interfere with MPI. If you like, I can give you the e-mail address of the OpenSSI developer who did this testing.

This Etherboot bug has also been noticed by a few other users. It's due to an old version of mknbi that I accidentally included in the remastered image. I've heard that the latest version of Etherboot supports PXE emulation. You could try that, since I know I've successfully added nodes with PXE.

The ssi-addnode command does not need to know what kind of network cards are used on new nodes. Instead what I did was take every network driver provided by Fedora Core 1 (on which the current 2.4 OpenSSI kernel is based), put them in the initrd, and enhance the linuxrc script to try loading each driver until `ifconfig eth0' successfully returns a network interface.

You're more than welcome to continue helping with testing. I'm currently working on other things right now (like our 2.6 kernel port), but I'm keeping a list of all OpenSSI/Knoppix issues reported by users, so that they can be fixed the next time I or somebody else remasters one of these CDs.

Regards,

Brian
