R for Windows server
Hello, You don't tell us much info (what processor(s) are exactly in your server?). You must know the following: 1) Windows server prioritizes client accesses over local running programs (but you say there is no other process slowing down R... is it deconnected from the network?), 2) Rgui uses only one processor (at least, if you did not customized the default installation). Take care that, for instance, with an Intel HyperThreading (HT) Pentium IV processor, the system is working as if it was a bi-processor config with a single processor... and the task manager will not report more than 50% of CPU use for RGui.exe. Thus, I can imagine that, if you have a bi-processor hyperthreading config, it could report only 25% of CPU use.

Hi, I need to run a burdensome simulation. I'm using a Dell PowerEdge 2850, 3.8 Ghz CPU, 2 Gb RAM, Windows server 2003, 32 bit. The task manager indicates that Rgui.exe is using 25% of the CPU speed. There is no other process that is slowing down R. Does anyone know if it's a limitation of R? If so, can I set up the program for the CPU usage like I do for the memory usage? Is there a version of R for servers? Thank you in advance, Marco Geraci --------------------------------- [[alternative HTML version deleted]]
