Thanks.
I do no have an alias setup for mpirun. Using the full path has the same result.
The output of $ mpirun -h
--------------------------------------------------------------------------------------
Synopsis: mpirun [options] <app>
mpirun [options] <where> <program> [<prog args>]
Description: Start an MPI application in LAM/MPI.
Notes:
[options] Zero or more of the options listed below.
<app> LAM/MPI appschema.
<where> List of LAM nodes and/or CPUs (examples
below).
<program> Must be a LAM/MPI program that either
invokes MPI_INIT or has exactly one of
its children invoke MPI_INIT.
<prog args> Optional list of command line arguments
to <program>.
Options:
-c <num> Run <num> copies of <program> (same as -np).
-c2c Use fast library (C2C) mode.
-client <rank> <host>:<port>
Run IMPI job; connect to the IMPI server <host>
at port <port> as IMPI client number <rank>.
-D Change current working directory of new
processes to the directory where the
executable resides.
-f Do not open stdio descriptors.
-ger Turn on GER mode.
-h Print this help message.
-lamd Use LAM daemon (LAMD) mode (opposite of -c2c).
-nger Turn off GER mode.
-np <num> Run <num> copies of <program> (same as -c)
-nsigs Don't catch signals.
-nx Don't export LAM_MPI_* environment variables.
-O Multicomputer is homogeneous.
-pty Use pty if stdout is a tty.
-s <nodeid> Load <program> from node <nodeid>.
-toff Enable tracing with generation initially off.
-ton, -t Enable tracing with generation initially on.
-v Be verbose.
-w / -nw Wait/don't wait for application to complete.
-wd <dir> Change current working directory of new
processes to <dir>.
-x <envlist> Export environment vars in <envlist>.
Nodes: n<list>, e.g., n0-3,5
CPUS: c<list>, e.g., c0-3,5
Extras: h (local node), o (origin node), N (all nodes), C (all CPUs)
Examples: mpirun n0-7 prog1
Executes "prog1" on nodes 0 through 7.
mpirun -lamd -x FOO=bar,DISPLAY N prog2
Executes "prog2" on all nodes using the LAMD RPI.
In the environment of each process, set FOO to the value
"bar", and set DISPLAY to the current value.
mpirun n0 N prog3
Run "prog3" on node 0, *and* all nodes. This executes *2*
copies on n0.
mpirun C prog4 arg1 arg2
Run "prog4" on each available CPU with command line
arguments of "arg1" and "arg2". If each node has a
CPU count of 1, the "C" is equivalent to "N". If at
least one node has a CPU count greater than 1, LAM
will run neighboring ranks of MPI_COMM_WORLD on that
node. For example, if node 0 has a CPU count of 4 and
node 1 has a CPU count of 2, "prog4" will have
MPI_COMM_WORLD ranks 0 through 3 on n0, and ranks 4
and 5 on n1.
mpirun c0 C prog5
Simlar to the "prog3" example above, this runs "prog5"
on CPU 0 *and* on each available CPU. This executes
*2* copies on the node where CPU 0 is (i.e., n0).
This is probably not a useful use of the "C" notation;
it is only shown here for an example.
Defaults: -c2c -w -nger -pty

Is it related to the kernel version? I try the same commands on Fedro with kernel 2.6.11, that's OK.
Sincerely,
Zhenxia Zhang
