Hi there
I've finally figured out the problem.
First, i changed the benchmark to DEISA Medium so that i could use a
wider range of machines, as it ( predictably ) used less than half of
the memory than the PRACE medium benchmark demanded. Then i

Dear Fabricio,
I reckon there is some inconsistency in the results you are obtaining.
The AMD 6380 is a 16-core model. I'm wondering how do you map the
process affinity while running on 8 cores.
Without controlling such mapping you can obtain substantial performance
variation at each execution.

First of all you should verify if multi-threading libraries
are conflicting with MPI parallelization.

Yes, i did look into it already.
I can send you the 'make.sys' files of all compilations if it helps .
TIA,

Because the problem is of a client of mine, and he is using this very
version , so I'm trying to reproduce the problem as exactly as possible.
Also, I'm a sysadmin, not a scientist . ;)
First of all: why do you want to use an old QE version? P.

Hi All
I'm facing a very strange situation with the above version of QE,
compiled with :
- intel 12.1.3
- mkl 10.0,
- fftw 3.2.2 ( OS package )
- openmpi 1.4.5
Running 'prace-medium' benchmark as a test .
