Hi there!
I'm learning MPI, and got really puzzled... Please take a look at this very
short code:
#include
#include "mpicxx.h"
using namespace std;
int main(int argc, char *argv[])
{
MPI::Init();
for (unsigned long t = 0; t < 1000; t++)
{
//If we are process 0:
eans that your processes are
caught in a busy wait. You could try to set mpi_yield_when_idle:
> gentryx@hex ~ $ cat .openmpi/mca-params.conf
> mpi_yield_when_idle=1
But I don't think this should be necessary.

Hey Balaji
I'm new at it too, but might be able to help you a bit.
A sigsegv error occurs usually when you try to access something in memory
that's not actually there. Like using a pointer that points to nothing. In my
short experience with MPI so far, I got this kind of message when I made
so

Yep, setting the card manually did not solve it.
I'm compiling the pre-release version now. Let's see if it works.

libopen-pal
libopen-pal: /usr/local/lib/libopen-pal.so /usr/local/lib/libopen-pal.la
So the library exists. How can I make mpiCC know it's location?
Thanks!
