I posted an issue with the Nasa Overflow 1.8 code and have traced it further to a program failure in the malloc areas of the code (data in these areas gets corrupted). Overflow is mostly fortran, but since it is an old program, it uses some c routines to do dynamic memory allocation. I'm still tracing down the problem, but could you enlighten me as to how OPENMPI does the malloc_hooks and intercepts memory allocation calls to run on a linux myrinet cluster.
Is there any easy way to debug what is happening?? I'm using brute force to track it down. Thanx, Bernie Borenstein The Boeing Company
