I do not know what would cause that, but note that `x lapw2 -qtl' is
not itself parallelized; `-p' means only “read parallel vector files”.
 This means you do not need `.machines'.  On the other hand, it reads
`.processes' to see how many vector files there should be, so if you
deleted that, that might have caused the error.

You probably need to `set SCRATCH=./' in this case.  Include the error
messages next time.
