[R] optimal hardware for computations in R?

2004-03-23 Thread Amit Ghosh
Hi, I am planning to buy a new PC for computing simulations in R under Linux. I was searching the web/mailing list-archives for useful hints about the optimal choice of hardware - surprisingly I found no recent topics. As far as I know, R doesn't use threads, so I think that there should be no

I recently ordered a computer which is intended to run both WindowsXP and Linux (of course both versions of R as well). Before placing the order, I discussed it with our system managers. They highly recommanded a system with one P4 CPU with Intel's so called hyper-threading technology over a

I thought there are quite a bit of evidence that Hyper-Threading may be more of a debit than credit under many conditions. Is that not so? We have a dual Xeon box running Linux, and we disabled the HT. If the computing tasks will ever reach the 3GB limit on memory, the best choice is still
