Dear Steven,
I had installed parallel Meep.
I got some error message when I execute sample code on 2
processor.
=========================================================================

Some deprecated features have been used. Set the
environment
variable GUILE_WARN_DEPRECATED to "detailed" and rerun
the
program to get more information. Set it to "no" to suppress
this
message.
=========================================================================
But When i execute sample code on 1 processor, That's ok.
