Dear Sir,

 I am running LAM /MPI on my code on DE algorithm which requires string evaluations which i do it on multiple computers . I am facing a problem with Jumpshot results.When i am using a uniform (homogeneous cluster) my results seem ok but when i use a heterogeneous cluster some time i face problem that my message send time becomes negative and message size becomes ZERO..what does it signify,

Shall i send in the printscreen of the jumpshot if its needed.

Regards
