Hi,
First of all, thanks again to everyone, especially Bill Gropp, for modifying MPE so it works with OpenMPI.
I did see a post somewhere about how the MPE animation code hasn't been updated in a while. Is it still something that should be good to use? It's a nice feature!
In our code, it works for a while and then crashes with this
sorry you're running into problems with the MPE animation code. As you've seen, every once in a while one of us (probably Bill) will go in and clean up MPE, but for the most part it's community supported. If you code up a fix, we'll gladly add it to MPE. [ snip error]
What is really odd is that one I ran the exact same code with the exact same command and it died much earlier while doing some kind of memory allocation. Unfortunately, I didn't capture that error and I can't make it happen again now.
such is the case with memory errors. A tool like valgrind can tell you what's going on.
Also, without digging through the code to figure out how the animations are being displayed, is there any documentation on that?
Appendix C of "Using MPI" might be the best overview. The book also walks through a simnple monte carlo example in section 3.10 on page 65. ==rob -- Rob Latham Mathematics and Computer Science Division Argonne National Lab, IL USA _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
