And that is the claim that I am stating you have not justified. 

Okay, here's one example:  TGICL, freely downloadable from NCBI.  Run
on a single computer:  ./tgicl file   Run on an SMP: ./tgicl -c N file
(where N is the number of parallel processes to spawn, not unlike -j
for GNU Make).  This is trivial to do.  How would you go about running
it on a batch-queued system?

Nice example. It needs pretty much no communication, which is why
it also runs on PVM. Yes, not unlike GNU make which also doesn't require much communication, other than a common file system which might be NFS.
