Re: [OMPI users] memalign usage in OpenMPI and it's consequences for 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 ;-) PeterT Ashley Pittman wrote: Simple malloc() returns pointers that are at least eight byte aligned

Took a look at the changes and that looks like it should work. It's certainly not in 1.3.3, but as long as you guys are on top of it, that relieves my concerns ;-) Thanks, PeterT Samuel K. Gutierrez wrote: Ticket created (#2040). I hope it's okay ;-). -- Samuel K. Gutierrez Los Alamos

2009-10-01 Thread Peter Thompson
We had a question from a user who had turned on memory debugging in TotalView and experience a memory event error Invalid memory alignment request. Having a 1.3.3 build of OpenMPI handy, I tested it and sure enough, saw the error. I traced it down to, surprise, a call to memalign. I find
