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?
