There is a lot of argument about whether hybrid MPI with OpenMP or MPI
alone is ideal for such machines. The optimum, again, depends on
factors which you haven't divulged.

Ok.. we are not planning to connect these machines together.. ! The
codes are going to be run on individual comps only !


However.. I have had trouble understanding the architecture of these
computers. Take for e.g a Dual core machine (one that is commonly
available for desktops these days). Is the memory shared between these
cores ? How about the cache ?

Going further..! What happens in these high end workstations ? Take
for instance the Double Dual core, and the double Quad core.. ! The
link has i sent has all the info. However I am not able to comprehend
them fully.

I have an MPI code working. Setting up OpenMP code is not that big a
deal I guess. A combo would involve some effort as well. I am ready to
put in the effort needed. However I need to know which one to put my
effort on ?

ganesh
