Yes, I am quite sure that you need at least 16GB to run SPEC MPIM2007.
See the FAQ at http://www.spec.org/mpi2007/docs/faq.html#MemoryMedium
Furthermore, the benchmark is designed to run on at least 16p.

Oh. Thank you for the information.
The machine has 6GM of RAM and I am creating 4 processes (for 4 cores). Are
you sure that it is because of lack of resources or some problem with the
network settings (I want to run the programs only on my server)?
Is there anyway to do this (I need to run o
How much memory is available on that quad core machine?
The minimum requirements for MPIM2007 are:
16GB of memory for the whole system or 1GB of memory per rank, whichever
is larger.
For MPIL2007 you need to use at least 64 processes and a minimum of 128GB
(2GB/process) is required.

Hi Gus,
Thanks for your well researched and thoughtful reply. It will take a bit of
time to absorb such a big and energetic doze. :)
I took your earlier advice regarding the optimization flags causing errors
in your case.

Hi Asad
I think the speed vs. accuracy tradeoff will always be there.
Getting both at the same time is kind of a holy grail,
everybody wants it!
Whoever asked you to get both gotta be kidding.
Somebody already suggested enforcing IEEE floating point standard,
if you want numerical accuracy and p

Thanks for your response !!
I have applied this patch. But i am on homogeneous environment. The

Does the "NODE 0: no room for lattice" message have any significance?
Could it be that for whatever reason the application is running out of

In fact, the simple programs that prints " I am process # " always works.
