Version: lamboot -V LAM 7.1.2/MPI 2 C++/ROMIO - Indiana University Arch: i486-pc-linux-gnu Prefix: /usr/lib/lam Configured by: buildd Configured on: Sun Mar 23 08:07:16 UTC 2008 Configure host: rothera SSI rpi: crtcp lamd sysv tcp usysv Below find the session info and the info from the instalaltion of Rmpi. In the install log from Rmpi, it says: checking whether MPICH2 is declared... no checking whether MPICH2 is declared... (cached) no So what went wrong? Do I have to start the "cluster" on the dual-core machine?
