Hello!
I need to purchase a new box, which I would like to optimize for good R
performance.
For the record, I will run Fedora Core 5 as and OS, and I wanted to know
if anyone has experience with how the following affects R performance:
- Is there a big advantage to having a 64-bit CPU over having a 32-bit?
- Does an Opteron offer any advantages over an Athlon, and if yes, does
it justify an investment of about US $75 more for equivalent listed speeds?
- Have people successfully multithreaded R computations, such as to
justify a dual-core CPU? I understand R itself does not multithread, but
of course it should be possible to write code that paralellizes
computations and I wanted to know if anyone has experience doing so and
gained large speed advantages by it.
Thanks,
Toby Muhlhfoer
