Well, just for the sake of proving the question of 64-bit processors being "faster" than their 32-bit counterparts ... I went and bought a 64-bit machine ...

My Original Dell Dual Xeon was 3.4 GHz, 2M cache, 1 G RAM, cheapest video card 80G 10,000 RPM disk drive, but was 32-bit Xeon chips.

Yesterday afternoon I got a Dell Dual Xeon 3.4 GHz, 2M cache, 1 G RAM, cheapest video card 40G 7,200 RPM disk drive, but is 64-bit Xeon chips.

After 16 hours I only have a little bit of work done and for comparison purposes the bulk of the work completed to this point has been LHC@Home which is useless for measuring as the work units can take any amount of time to process ...

But of the 9 LHC@Home work units, 1 failed download (for all of us) 6 have validated and have been granted credit and 2 are pending.

For the other projects I have 2 Trickles for CPDN (I attached there first and have 4 CPDN work units ... be interesting if it maintains 4 in the buffer or not - my older Xeon has two in flight right now, so I AM curious) and one Einstein@Home work unit which is pending at this moment.

I still have to attach it to Predictor@Home and SETI@Home ...

64-Bits, Help or Hinderance

Hi Paul !

This is another view at the 32/64 bit topic :

BOINC benchmarks

-rg-

P.S. First time I try to put HMTL tags in a post - bound to fail ...

... actually not - thanks to BOINC Wiki's useful hints.

Yeah... It is really going

Yeah...

It is really going to take a week or two to know for sure. All of the projects work has variability built into the processing. So, I have, at this point only a few data points with the machine completing 17 results since I got it. And that is not enough data to be sure of anything...
