Nowdays we hear about intel dual core processor, An Intel dual-core
processor consists of two complete execution cores in one physical processor
both running at the same frequency. Both cores share the same packaging and
the same interface with the chipset/memory.
Can I use MPI library to communic
I have what is probably a simple question (I hope). I have built
openmpi-1.1.1 from source using gfortran on Mac OS X 10.4.7. I can
run parallel jobs on my own using the mpiexec -np command. My
machinefile contains the lines:
tachyon.a04.aist.go.jp
tachyon.a04.aist.go.jp

Hi,
1)Today I have compiled my first MPI application by using OPEN MPI
compiler mpicc.
A very strange thing happens, a program that worked
correctly with MPICH2 now gives me an error.
I show you the error
message that appears when I execute it:
*** An error occurred in
MPI_Lookup_name

More specifically, Sun has joined the Open MPI project. However, I believe
that their first officially supported version will be v1.2 (i.e., it hasn't
been released yet).

Eh? You mean all of those examples
My opinion would be to use pthreads, for a couple of reasons:
1. You don't need an OMP aware compiler; any old compiler would do.
2. The pthread library is more well adapted and hence might be more
optimized than the code emitted from an OMP compiler.
