Not sure if this will be of any use -- sure isn't any use to me as I don't even begin to understand, but here's the output from the strace... It did not attach to the wrf.exe process which I wanted, but it attached to the mpi process which was running the wrf.exe, at least one of the processes. There are two at runtime.<BR>
