Re: [OMPI devel] RFC: Change PML error handler signature

The keyword here is consolidation. It's not about violating the initial design, it is more about keeping the design consistent. I think this change is good from an overall perspective, but now we have two ways to report similar types of problems. In other words, I don't see how we can fail sendi

Re: [OMPI devel] sendrecv_replace: long time to allocate/free memory

2010-04-23 Thread George Bosilca
If you use any kind of high performance network that require memory registration for communications, then this high cost for the MPI_Alloc_mem will be hidden by the communications. However, the MPI_Alloc_mem function seems horribly complicated to me, as we do the whole "find-the-right-allocator"

Timur, Thanks for the very detailed analysis of the problem. Based on your observations, I was able to track down the issue pretty quickly. In few words, the 64 bits machine sent a pointer to the 32 bits one, and expected that it will get it back untouched. Unfortunately, on the 32 bits machine
