Matt,

How come? I check and it is using the simple partitioner and no random number generator is called. How come when I run it it gives a different partitioning than in the output file? The vectors also have different partitionings. Are the output files out of date?

In my branch, ex15 has not had its partitioning replaced. It is still using ParMetis. I can do it. Matt
