Hi all, I got problem with running program on a cluster. I used the following command. *my_hosts* is a file containing 3 hosts while *testMPI* is a very simple MPI program. ==========================================
*mpirun -np 2 --hostfile ./my_hosts ./testMPImpirun -np 2 --machinefile ./my_hosts ./testMPImpirun -np 2 --f ./my_hosts ./testMPI* ========================================== And the output is like this. ========================================== *invalid "local" arg: --hostfileusage:mpiexec [-h or -help or --help] # get this messagempiexec -file filename # (or -f) filename contains XML job descriptionmpiexec [global args] [local args] executable [args] where global args may be -l # line labels by MPI rank -bnr # MPICH1 compatibility mode -machinefile # file mapping procs to machines -s <spec> # direct stdin to "all" or 1,2 or 2-4,6 -1 # override default of trying 1st proc locally -ifhn # network interface to use locally -tv # run procs under totalview (must be installed) -tvsu # totalview startup only -gdb # run procs under gdb -m # merge output lines (default with gdb) -a # means assign this alias to the job -ecfn # output_xml_exit_codes_filename -recvtimeout <integer_val> # timeout for recvs to fail (e.g. from mpd daemon) -g<local arg name> # global version of local arg (below) and local args may be -n <n> or -np <n> # number of processes to start -wdir <dirname> # working directory to start in -umask <umask> # umask for remote process -path <dirname> # place to look for executables -host <hostname> # host to start on -soft <spec> # modifier of -n value -arch <arch> # arch type to start on (not implemented) -envall # pass all env vars in current environment -envnone # pass no env vars -envlist <list of env var names> # pass current values of these vars -env <name> <value> # pass this value of this env varmpiexec [global args] [local args] executable args : [local args] executable...mpiexec -gdba jobid # gdb-attach to existing jobidmpiexec -configfile filename # filename contains cmd line segs as lines (See User Guide for more details)Examples: mpiexec -l -n 10 cpi 100 mpiexec -genv QPL_LICENSE 4705 -n 3 a.out mpiexec -n 1 -host foo master : -n 4 -host mysmp slave* ========================================== Another problem is that I cannot get the version of MPI.
