I wonder if someone might have possible ideas to explore as to why this
program might not be working correctly under TotalView. Essentially a
user is running a very simple hello world like program that does this:
#include
#include
#include
int main(int argc, char **argv)
{

Hi Ralph,
We've had a number of user complaints about this. Since it seems on the face
of it that it is a debugger issue, it may have not made it's way back here. Is
your objection that the patch basically aborts if it get

environment.
Is there some particular problem causing what you see? We have no other reports
of this issue, and orterun has had that code forever.

We've gotten a few reports of problems with memory debugging when using
OpenMPI under TotalView. Usually, TotalView will attach tot he
processes started after an MPI_Init. However in the case where memory
debugging is enabled, things seemed to run away or fail. My analysis
showed that we ha

Hi,
About a month ago, this topic was di
the executables and shared libraries, and we would then
be able to debug with Open MPI without a problem. I'm not sure if this
is the best place to offer that suggestion, but I imagine it's not a bad
place to start. ;-)

Hi Jeff,
Sorry, speaking in shorthand again.

I've tried a few builds of 1.4 on Snow Leopard, and trying to start up TotalView

The value of 4 might be invalid (though maybe on a 32b machine, it would be
okay?) but it's enough to allow TotalView to continue on without raising a
memory event, so I'm okay with it ;-)
