I need to do some performance tests on my mpi app. I simply want to determine
how long it takes for my sends from one process to be received by another
process.
Here is the code I used as my example for non-blocking send/receive...
if( myrank == 0 ) {
/* Post a receive, send a message,
The data that I want to send via MPI is in the form of a struct:
struct myDataStruct {
struct subData1 {
int position[2];
int length[2];
};
struct subData2 {
float *data1;
float *data2;
float *data3;
float *data4;
};
struct subData3 {
Actually, that wasn't the problem. My code is working now with no changes to
it. Not sure what the problem was but it wasn't the called to MPI_Send
blocking.

I have a glut application I am trying to add MPI to. In the display callback,
for rank >= 1, I want to send data to the rank =0 process. I am not concerned
at this point about sending data from the rank 0 process back to the rank >= 1
process, so my data is one direction. I would like to
I have a glut app I am infusing with MPI calls... The glut init appears to fail
in the rank1 processes. How do I accomplish this, that is, parallel rendering
with GLUT and MPI?

I would like to give Open MPI a test drive on some machines I have in my lab
and I have a few questions...
The machines are RHEL 5.4 machines and an older version of Open MPI was already
installed. I understand from the faq that I should not simply over write the
old installation, but would
