We are currently running Nwchem over AMD CPUS, and we plan to buy new hardware equipment for the next coming year. Thus, we would like to know which hardware architecture would be the best to run future versions of Nwchem.
So my question is : is x86 CPUS still the best option or would it be more profitable to run future Nwchem versions on new architectures like GPU and/or Intel Xeon Phi ?
