I see nothing wrong with the make output?

That error message gives very little information to diagnose the problem.
Maybe you can recompile with debug information, then it will print a more
meaningfull backtrace.
Also, please compare your Makefile with the attached one.

GotoBLAS needs to be called as Fortran BLAS, so you need to switch from
CBLAS to FBLAS.

Yes, I believe we are somehow limited by memory performance. Here are
some numbers from a dual Opteron 2352 system, which has much more memory
bandwidth:

something can be tuned here?

Alternatively, you can also ask ClusterVision support to install an
Infinipath-psm capable OpenMPI on your cluster, so you can continue using
OpenMPI.

Alas, it
when this limit is exceeded is:
No free InfiniPath contexts available on /dev/ipath
"
It looks like OpenMPI is running into the context limit, apparently 4
inthis case. Can I do the context sharing mentioned with OpenMPI?

Lazarus isn't a Pascal compiler, but an IDE.

ary expects them to be $1c8 bytes.
Conclusion: Opaque pointers should not be declared with .comm, they should
just be referenced.
I didn't tell my system details yet: I'm using OpenSuSE 10 on the x86_64
architecture. The compiler does not seem to be of any influence: the
result is the same with Gcc, Intel C and Pathscale.
