Best and fast configuration for running ATK
« on: January 19, 2009, 09:35 »
Hi all,

I tried ATK on a 64-bit linux machine but I'll re-install my system. For the best ATK performance, which version would you recommend? 32-bit or 64-bit? I'll use mpi to parallelize the ATK.

Cheers
Serhan

There is no doubt that ATK performs best in 64-bit on a 64-bit machine (i.e. on the x86_64 architecture). The benefit over 32-bit ATK on a 32-bit machine is about 2 times (twice as fast), and 30-50% faster compared to 32-bit ATK on a x86_64 machine.
