Most serious supercomputing scientists -- those who have finite cpu allotments in particular -- put in checkpointing when they realize it saves them valuable resources. Until they lose work or money, it's not a priority. > BTW, I like your code. I had a script written for me in the past > (by Greg Lindahl in a galaxy far-far away). Hey, and here I was avoiding saying "You guys don't remember me talking about easy backtrace in conferences in 2000 and 2001? I was pretty insufferably on the topic..." That implementation used gdb and had zero overhead other than the memory gdb took. But fewer processes is always better, and OpenMPI and Intel and PathScale MPI & compilers all use a library implementation somewhat like Mark's. -- greg
