Hi,
I am a newbie and want to use LAM-MPI to checkpoint/restart my MPI application.
I have installed blcr-0.4.2 and lam-7.1.2, but entouner some problems.
My environment is RedHat 9 with kernel 2.4.20-8. LAM-MPI and blcr is installed in /home/cesc53/local.
1. I compile application with
$ mpicc hello_mpi.c -L/home/cesc53/local/lib -lcr -o hello_mpi
The error information is :
/home/cesc53/local/lib/libmpi.a(malloc.o)(.text+0x30e9): In function `ptmalloc_init':
: undefined reference to `pthread_atfork'
collect2: ld returned 1 exit status
2. Then I complie with
$ mpicc hello_mpi.c -o hello_mpi
That is OK.
I run application with
$ mpirun -ssi rpi crtcp C ./hello_mpi
It seems that the commad has syntax error. Following is displayed:
-----------------------------------------------------------------------------
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>.

Could you tell me what I have done wrong? And how to checkpoint a MPI application using LAM-MPI
with blcr?Thanks.
Regards,
Zhenxia Zhang
