Hello Ryan,
I have been running a similar heterogeneous setup in my lab; i.e., a mix of
ppc64 and x86_64 systems connected by ethernet and InfiniBand. In trying to
replicate your problem, what I see is that it is not an issue of processor
heterogeneity, but rather an issue with heterogeneous tran
Dear Reeder,
It does not work. I do think they are from the fortran programs
I'm using (they are files included from the BLACS installation
package, not written by my own.
The thing is last time when I was using g77, it caused no problem...
thanks for your help.
Linwei.

Linwei,
Have you tried using -funderscoring with gfortran. I don't think the
trouble you are having is caused by having g77 and gfortran both
installed.
Do you know where the unreferenced symbols (_s_wsle, _e_wsle, etc )
are supposed to be coming from. If they are in your fortran programs
Dear Reeder,
I've tried add gfortran flag "-fno-underscoring", but the same
errors persist...
Is that possible because that I have both g77 and gfortran in my
computer?
Best,
Linwei

I would make a stronger statement than that: progress threads are
totally broken in v1.2. Don't bother trying them.

Looking at the orignal email, it looks like Alberto might not have the
persistent daemon up since he's using OMPI 1.2,, so he'll need to start
the persistent daemon and establish a universe before the client server

Linwei,
Is there a problem with trailing underscores. Are you linking c/c++
files with fortran. Do the _s_wsle family members need to have a
trailing underscore
where are the unrefernced symbols supposed to be coming from. If they
have a trailing underscore in their names you probably nee
Dear Dr. Simon,
Do I need to remove g77 from my computer then? Since after installing
gfortran (for Leopard), there is some link problem with gfortran..
When I try to build some routines in the BLACS, it gives error like:
Undefined symbols:
"_s_wsle", referenced from:
_MAIN__ in tc_fC

Sorry for the delay in replying.
Believe it or not, almost this exact issue just came up with the IBM
Benchmark Center; they were using Open MPI with MPIRandomAccess and
experiencing problems with running out of memory. We didn't get a

I assume you are using some variant of OMPI 1.2?
When last I checked, which admittedly was quite a while ago, this worked on
the 1.2.x series. However, I note something here that may be a problem. In
the 1.2.x series, we do not have a global publish/lookup service - the

First of all, many thanks for your quick response.

Unfortunately, IRIX is not on our list of supported platforms --
there's no one on the current development team who supports it. If
someone wants to join the Open MPI project and support IRIX, that
would be great. :-)

It seems as though this problem is fixed with version 1.2.6. I did not
get the error when using the packages from Debin Sid who use this
version instead of 1.2.5.

g77 is outated. You have to switch to gfortran (it's descendant).
It should work, and will be far more efficient.
Be carefull to install a version consistent with your gcc.
