Hi, I've just installed frozen on my laptop (Thinkpad 570, PII 366, 64MB, custom 2.2.14 kernel), and I'm having trouble getting mpi to work. I want to develop a parallel program on my machine, and then do production runs on something more serious. In any case, I installed mpich and then changed the /etc/mpich/machines.LINUX file to read 127.0.0.1 (instead of localhost, so that I don't need a nameserver to run mpi). I then made a .rhosts file that read
127.0.0.1 boo (my username on the laptop is boo). To test it, I ran rsh 127.0.0.1 ls and it worked fine. Then I tried to compile the tests in /usr/doc/mpich/examples/code. I ran mpireconfig on the makefile and then make cpi. Everything seemed to make fine, but when I ran cpi (mpirun -np 1 cpi), it just sat there at 97% of cpu usage, stuck at MPI_Init(). Is there something that I'm missing? I'd appreciate any help. Thanks, Walter Landry [EMAIL PROTECTED] p.s. I couldn't use lam. The parallel library I use doesn't seem to want to compile with lam. It has no problem compiling with mpich.
