Re: [phenixbb] Hardward phenix.refine

Colin, check out the first option in the FAQ at https://www.phenix-online.org/documentation/faqs/refine.html A core i7 and a Xeon of the same generation are equally fast if their frequency is the same. The main differences are that - Xeon E3 supports ECC memory (most core i* don't) - Xeon E5 supports Dual-CPU (core i* is just one) - Xeon E7 supports multi-CPU and is very expensive - most Xeons don't have built-in graphics whereas most core i* do There are many other small differences but most of them irrelevant; inspect the Wikipedia pages! Xeons won't be faster with phenix.refine; a core i7 already has enough cores - to increase their usage you'll have to recompile as per the FAQ. HTH, Kay

Dear all,

Having read the FAQ regarding hardware I have a few ideas but would greatly appreciate any input from the community or developers.

Would anyone like to suggest the best configuration of hardware for running phenix.refine? I mainly operate in OSX but have no issue with switching operating system if I can get a faster setup. My current thoughts are either something running a 4GHz Quad core i7 or an alternative would be a 3.7GHz Quad-Core Intel Xeon E5 (iMac v Mac Pro) or equivalent Linux builds.

I know that the i7 is reasonably fast as I have this setup in a different machine and phenix.refine runs reasonably quickly but as ever I would like it to be faster. Budget is not unlimited by any means but I would be interested in learning what an optimal setup might look like.

Many thanks,

Colin
