31) Message boards : Number crunching : Is it worth it? (Message 28601) Posted 11 May 2007 by Warped Post: I\'ve been running various programmes and monitoring systems on a variety of hardware over the years. In my experience, Prime95 seemed to be the most intensive user of the CPU and raised the temperature more than any other distributed project. In fact this is used for stress testing hardware. I found that MBM (Motherboard Monitor) is the most user-friendly monitoring sotware but can only get another programme, Speedfan, to work on my single processor HP notebook which also has the air intake at the bottom. My dual-core desktop is monitored by some intel software. Having said all that, I have never seen a CPU temperature higher than about 80C. I was under the impression that intel processors automatically slow down to protect themselves and that the dual-core design is much more energy (and therfore heat) efficient than previous designs. Under extreme conditions (ambient temperature approaching 40C, both cores crunching away and a DVD being watched at the same time on the dual-core machine, the temperature remains under 60C. All that happens is that the fan(s) speed up. Granted, this is a desktop. Nevertheless, I would think that 99C is about at self-destruct levels.

Laptops are much more sensitive to the impact of higher temperatures than is the case with desktop machines In addition, their cooling capacity is considerable lower. I would think that any temperature over 75C should be avoided. 2. Running only one model by telling it to use only one processor will result in lower temperatures, even though it uses that one processor\'s free capacity. Make sure (via task manager) that the priority is on low.
33) Message boards : Number crunching : Error on File Upload (Message 28253) Posted 29 Apr 2007 by Warped Post: If the servers are full, does that mean no further analysis is being done with all the data from the models we are running? With all the hype about Climate Change and Al Gore\'s movie (An Inconvenient Truth), together with ever increasing PC processing speeds, I would expect the amount of data that is likely to be on the way to be increasing rapidly. Surely the idea is to better predict the future climate (as the name of the project would suggest). Merely stashing this data on servers does not seem to be very logical. I would think it should be analysed and then archived at the same rate as it is arriving or you\'re on a hiding to nothing.
