Except that it's hard to determine from the information available to the application all the necessary parameters. For example, an Athlon 3800+ may be a single or dual core model - running at 2.4 or 2.0GHz - the dual core would thereofore per core be around 20% slower.

It's possible to find out what cache-size the processor is, but finding out how fast the memory is, and how much effect the speed of the memory has is much harder [as that partly depends on what else is going on in the machine at the same time].


Hosts' data have the number of CPUs installed, and having a big (because it's BIG) number of hosts in the database probably the average wouldn't be so far from reality


Running rosetta for 10 seconds without majorly changing how Rosetta works would not achieve anything useful, because it wouldn't finish working out a single model (decoy) of a protein in that time - not even enough to figure out how long it would take, I would think.

Maybe i didn't explain myself, sorry, english is my second language.
I meant to ADD a benchmark (maybe a simple loop increasing a variable for 10 secs or less) before starting to crunch the data.

Just my 2 cents opinion:

If real speed is the problem, why don't add a little 10 secs benchmark before the initialization? In this way , with the WU's result and times, will come the real base to calculate the math done and the points to give.

[edit]
Another way could be an average speed for every single class of CPU.
For each host you have the CPU used and the BOINC benchmark result... it shouldn't be difficoult to calculate such average...

3) Message boards : Number crunching : CPU Upgrade Suggestions Anyone? (Message 29434)

I'd wait for a CPU upgrade... Intel will come out with the new Core 2 Quad (4 cores... wow!) in november, so probably the Core 2 Duo will be cheaper
4) Message boards : Number crunching : Report problems with Rosetta version 5.32 (Message 29433)

Not an error but strange thing:

new 5.32 works fine on my P4 1.8Ghz, 1Gb RAM (XP pro sp2), but after the first hour working it suspended at 19.9%... when it restarted it jumped immediatly at 41.2%.
Is it normal?
