Hello-- I am tryign to test our scyld cluster with the cpi program. The machinefile, "mfile" contains: 3:2 4:2 The command I am trying to run is: mpirun -map 3:4:3:4 -v -machinefile mfile cpi The output I get is: running /home/henken/e2k/jobs/cpi on 4 LINUX ch_p4 processors Created /home/henken/e2k/jobs/PI26817 Process 0 on eio5 pi is approximately 3.1416009869231254, Error is 0.0000083333333323 wall clock time = 0.026838 also, if I add a -t to the mpirun command, I get: running /home/henken/e2k/jobs/cpi on 4 LINUX ch_p4 processors Procgroup file: 3 1 /home/henken/e2k/jobs/cpi 4 2 /home/henken/e2k/jobs/cpi rcp: /home/henken/e2k/jobs/PI26716: No such file or directory /usr/bin/bpsh -n 3 /home/henken/e2k/jobs/cpi -p4pg /home/henken/e2k/jobs/PI26716 -p4wd /home/henken/e2k/jobs Does anyone know why the program is failing to run multiple times on the SMP nodes? Or why it doesnt run on the bproc node4(eio6)? Nicholas Henke
