[C-mpi-discuss] Several Problems running C-MPI

[Xi D. <xd...@ii...>]

Hi all,
I followed the the quick start on the home page 
(http://c-mpi.sourceforge.net/), and it was all good
when I was doing the setup and configure steps with mpich2-1.2.1p1, and 
my machine is Sicortex072. But I met problems while the make step.

At the beginning, it turned out the error of 
"//home/xduan/mpich2-1.2.1p1-install/bin/mpdroot: open failed for root's 
mpd conf filempdlistjobs (__init__ 1208): forked process failed; 
status=255/".
Then I followed the discuss threads at 
http://lists.mcs.anl.gov/pipermail/mpich-discuss/2010-March/006782.html, 
and set /mpd.conf /file at both//etc// and//usr/etc//, moreover, I 
didn't include
the /"MPD_USE_ROOT_MPD=1" /thing due to I just use a regular user 
started ring. But it returned the error at 
/"test/mpirpc/test-ping.out.failed"/, which says /"srun: error: Unable 
to allocate resources: No partition specified or system default partition"/.

So I realized I need to run multiple instance instead of just single 
process. Then I made the ring and used "srun" to start multiple 
processes on different machines. However, I still get the error message 
at /"test/mpirpc/test-ping.out.failed"/, the following paragraph is the 
error code:

/hello
hello

tag=0, MPI_COMM_WORLD, request=0x120115c30) failed
MPI_Isend(96).: Invalid rank has value 1 but must be nonnegative and 
less than 1

srun: error: task 0-1: Exited with exit code 1
un: error: task 1: Exited with exit code 1/

Now I am stopped by this problem, could anyone provide any idea? BTW, I 
also tried a root-started ring with /"MPD_USE_ROOT_MPD=1" /in two 
locations. Nevertheless, they have the same problem.

Looking forward to your responses.

Thanks,
