Let me add ... In all the years I've watched Mathgroup, I have yet to see a Question go Unanswered....and, invariably, every Question gets an Answer from Mathgroup showing various methods for doing what they want with Mathematica.... How on Earth can it get any better then that??? jerry blimbaum From: James Womack Sent: Wednesday, October 19, 2011 8:18 AM To: mathgroup Cc: mathgroup at smc.vnet.net Subject: [mg122202] Re: Low CPU usage I agree. It is a steep learning curve, but once you spend a while using it you begin to see just how powerful a tool it is! On 19 October 2011 10:35, mathgroup <fizzymath at knology.net> wrote: Ben... I can't answer your question , however, would like , for what it's worth, to tell you my experience.... When I first started Mathematica it was frustrating as hell.....the only thing that saved me from throwing in the towel was Mathgroup....and their Expertise is FREE....Amazing!!! After a while I reached the point where you can't tear me away from Mathematica....there are too many things of value in it for me....too many things that I can do with it that, by hand, would be abominable or impossible.....I think Mathematica has endless applications whether Education or Professionally and is only hampered by the Imagination of the User... jerry blimbaum -----Original Message----- From: Ben Gear Sent: Tuesday, October 18, 2011 6:42 AM To: mathgroup at smc.vnet.net Subject: Low CPU usage All, Frequently when Mathematica is trying to evaluate an expression the CPU usage on my machine seems remarkably low; one core will be ~70% with the others only up to ~20%. I'd expect one core at least to be maxed out. The hard disk isn't being hammered, RAM usage doesn't increase, so my question is: where is the bottle neck? I'm new to Mathematica so is this normal behaviour? I'm using 64 bit Win 7. On a related note some of my expressions just don't seem to ever return, particularly those involving Sum[] - again, is this normal? My experience with Mathematica so far has mostly been frustrating. I can get it to do dead simple things, but anything vaguely complex it seems to choke on. Just getting it to replicate what I can do by hand seems an uphill struggle. Do many use it professionally or is it mainly used in education? Regards, Ben
