Charm++ parallel programming system

[Nicolas Bock <nicolasbock AT gmail.com>]

Hi,

please have a look at the attached code. The code consists of two chare arrays, one holding some data, one doing some work. The main code calls a reduction on the Work array which gets information from the Data array to do something. When I run this (make run) on more than one PE with the GreedyCommLB load balancer the code segfaults at random points when the load balancer kicks in. I think what's going on is that the Data::info() call in Work::doSomething() suspends the chare and it just so happens that it sometimes is migrated while being suspended. If I comment out the code block that calls Data::info() the program executes just fine.

Is what I am thinking correct, or is there another problem in the code that I have overlooked?

Thanks already,

nick
