Oups, sorry !

I followed these steps :

1) Install a debian system (sarge 3.1r2).

2) Use a 2.6.9 kernel patched with bproc 4.0.0pre8 (http://bproc.sourceforge.net)
the options CONFIG_BPROC, CONFIG_ROMFS_FS, CONFIG_BLK_DEV_RAM, CONFIG_BLK_DEV_INITRD, CONFIG_TMPFS where activated via the 'make menuconfig' command.

3) install bproc 4.0.0.pre8

4) install beoboot-cm1.10

5) load bproc modules

6) Install open-mpi V1.1.1

Hope this will help.

Thanks,
        Laurent.

Could you please clarify - what "Bproc kernel patch" are you referring to?

Thanks
Ralph
