Subject: Re: [OMPI users] Problem building OpenMPI 1.4.4 with PGI 11.7 compilers
From: Gustavo Correa (gus_at_[hidden])
Date: 2011-11-09 13:11:42

Hi Jeff

Thank you for your suggestion!
You're right.
It works with '-tp=shanghai-64', which is great.
A snippet of the make log where I had errors before is included below,
the crucial line being:

libtool: link: pgcc -shared -fpic -DPIC .libs/dummy.o -lnsl -lutil -lc -tp=shanghai-64 -Wl,-soname -Wl, -o .libs/

Somehow the OMPI 1.4.4 parses correctly the syntax with the equal sign,
but leaves it at '-tp' only if there is no equal sign.
If I understood right the patch you mentioned, the intent was to allow both syntaxes.

FYI, I just checked the man pages of various PGI compiler releases,
and they seem to have changed the syntax from '-tp target_processor'
to '-tp=target_processor' in release 11. Up to release 10 the syntax was the
former, although release 11 seems to accept both syntaxes.

So, if one is not using the latest syntax and the latest PGI version,
one is out of luck with OpenMPI 1.4.4, or must not use the '-tp target_processor' flag, right?
Could the patch be patched to make the parsing a bit more forgiving?
[Maybe I am asking for too much, since 1.4.4 is probably the final release of the 1.4 series.]

Many thanks for your help.
Gus Correa
