I'm not sure how this could be happening. As far as I can see, the call
to corpac() in runmd() [which writes to unit 13] is inside an "if (master)"
block, and so will only be executed by the master node. Does this file go
away with just one node? Get bigger as the number of nodes gets bigger?
Since you clearly know you way around the code, you should be able to
track down most of these things youself.
....good luck...dac
