Hi -
looking through the archives, I didnt find anything helpful, so Im reporting
my own observations:
I have compiled sander (amber7) on an SGI O3000 with IRIX64 6.5, and MPI
3.2.0.7, with MIPS Pro 7.3.1.2m.
Running a MD simulation of a protein on this machine, everything goes fine
and my MD
calculation runs through smoothly...however, we just got a new machine
(O3000 with IRIX 6.5, and MPI 4.3 MPT 1.8,
but no compiler on it) and running my sander executable on it, I get
basically identical results, my simulation runs
through to the end, but now I get the following error message
MPI: Program /home/foxt/amber7/exe_mpi/sander, Rank 0, Process 6182
received signal SIGSEGV(11)
MPI: --------stack traceback-------
sh: dbx: not found
MPI: -----stack traceback ends-----
MPI: Program /home/foxt/amber7/exe_mpi/sander, Rank 0, Process 6182:
Dumping core on signal SIGSEGV(11) into directory
/home/foxt/PROJECTS/LIE_FXA/LIE_RUNS/RUNS_RST
MPI: MPI_COMM_WORLD rank 0 has terminated without calling MPI_Finalize()
MPI: aborting job
MPI: Received signal 11
The output stops before the final timing information ("5. TIMINGS") - but
this could be a buffering issue...
minimizations are no problem, just MD calculations.
To be honest, this behavior is more an annoyance, as I dont get the timing
information and a lot of garbage
in my log-files (and, yes, lots of core dumps that I have to remove), but
still...I have looked through the code
but couldnt find anything obvious, but this is probalbly as Im not familiar
enough with MPI...
Any idea/suggestion ?
