Re^2: Small cluster for Firefly

Veinardi Suendo

Dear Alex,

I prefer myself to have a linux based cluster using CentOS 5, because all of PCs are installed with it. In your opinion, MPICH2 is better than openmpi? Please if you have a more detail reference about it or even a detail recipe.

Thank you in advance,

Best regards,

Please share your recipes to build small cluster for Firefly. Until now, I calculate in SMP system only (Centos 5.3, Openmpi 1.2.8, Intel Compiler Suite 11). Thank you very much in advance.
