Processor usage increase.

Processor usage increase.

Processor usage increase.

(OP)
I am running FEA analysis on different machines and notices that any one of them use more than 50 % of the microprocessor speed. They both are modern Dell precision systems (670 and 690) with Xenon processor.

Is there any way to increase the use of the processor and there fore reduce the processing time (between 5-6 hours now)?.

I am using XP 32 bits: any advantage on going to 64 bits version?

Thanks.

Turn off hyperthreading.

RE: Processor usage increase.

Depending on version, I believe FEA will run multi processor.  64 bit will make a difference due to processor speed and amount of ram.  What version are you running?

RE: Processor usage increase.

the second CPU you are using is the hyperthreading.

on a dual cpu (or dual core) system you can enable multithreading for the FE calculation.

on a side note, what are you running for 5-6 hours? a transient shock response?

RE: Processor usage increase.

64 bit version has been really fantastic, thusfar.  However, it may also be the machines that we run.  I have 2 dual processor machines with AMD Opteron processors.  Where they seem to outshine the Intel, is in the fact that they have no Front Side Bus.  Each CPU accesses memory directly, and has its own DIMMS for each processor.  So while it's more expensive to buy, (due to more memory) there are no "bottlenecks" like i'm so used to on my Xeon box.

I don't see how you can go wrong with 64 bit, but I am just much more partial to 64 bit computing with Opteron processors... (dual processor, but not dual core - the dual cores don't impress me with the current clock speeds and on-die cache - too much money)
