[mpich-discuss] MPE animation crash

[Schilling, Herbert W. (GRC-VE00)]

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

 *** End of error message ***

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.

Also, without digging through the code to figure out how the animations are being displayed, is there any documentation on that?

Thanks!
