1) Message boards : Number crunching : Amd dual vs quad core (Message 59883) Posted 28 Feb 2009 by westerj Post: Thanks everyones' thoughts on all this. Is the consensus here that 64-bit is no help and won't be leveraged, or that the code to optimize the process on AMD64 is not deemed worthy? In the mean time, I think I'll back off my R@H to 2 cores, and run the other two on a few other projects. Will look for a 16bit Boinc client maybe too :^). JW.

That measn that you not only need to buy a card you need to buy a power suplly too! That could also mean you will be getting into the field of a do-it-yourselfer! Replacing power a supply is NOT hard, they are sorta like chicken mcnuggets, parts is parts! Not totally, but sorta.[/quote] ======================================= Mikey, I have never purchased a system!! Always build em. Its a Asus M3A78-T board, 8 GB@1066, and a radeon 2600XT.The other one is home built too, but from Ebay sources. Such fun! Would like to get CPUs a cranking before messing with Gfx cards, but wont write it off! Since the code seems to be compiled for 386 and 32 bit... that sounds like a good place to start first! =======================================

It runs less then 1% of the time. As for Rosetta, you might consider increasing your runtimes gradually over time. This setting is in your Rosetta preferences here on the website. This will save the overhead of scheduler hits and file downloads, and just crunch a few more models out of each task. So instead of managing 200 tasks per day to keep the machine busy, you could drop that to 1 task per core. Again, the overhead to manage the tasks and make more scheduler requests is negligable, but it helps the overhead on the project servers too. Lets look @ CPU before GPU, Howsabout? I'd been running 4 simultaneous processes, all soaking up a lovely 100Pct of CPU. The assesment of Boinc app doing anything was dumb on my part. The binary is packaged as minirosetta_1.54_x86_64-pc-linux-gnu, but shows up as: file rosetta_beta_5.98_x86_64-pc-linux-gnu ELF 32-bit LSB executable, Intel 80386, version 1 (GNU/Linux), statically linked, stripped 32Bit? Compiled for 386? Am I missing something here?

How far will a Kooler Master 650 get me? The GTX 295 are about $400 plus?? Maybe my Tax refund. Any cards made in the US?
5) Message boards : Number crunching : Amd dual vs quad core (Message 59747) Posted 23 Feb 2009 by westerj Post: Hi All, I've built 2 Systems over the past while and want to optimize them. First one is a Tyan Thunder K8WE w/ 2 X Opteron 252 @ 2.6 GHz and 3 GB RAM. Second one is Asus M3A78-T with Phenom Quad @ 3.0 with 8GB RAM. (Bios 8.02) The Phenom machine does about 200 Work Units/day, and I will restart the Tyan one tomorrow... Both are 100% stock settings. Both Run Fedora 10 @ 64 Bit. Will I be best off running the Boinc Client that comes with Fedora, or should I get or make one that runs with SSE3 or other optimization at compile time? [root@phenom ~]# rpm -qa \| grep boinc boinc-client-6.4.5-2.20081217svn.fc10.x86_64 boinc-manager-6.4.5-2.20081217svn.fc10.x86_64 Thanks! John W. ....oh.. and there are 3 big fat PCI-Express slots on the M3A78-T. Is Cuda the hot ticket? Is there a "Best" Cuda card for buck? # Make me a sandwich. no make it yourself. Sudo make me a sandwich. OK #

7) Message boards : Rosetta@home Science : 10 reasons I crunch R@H and you should too (Message 59705) Posted 21 Feb 2009 by westerj Post: Perhaps it will encourage the medical profession to address diseases more an not just symptoms. Once we understand proteins better, we'll unlock magic that we didn't know existed. Later, we'll look back on our current state of affairs and be proud of what we contributed to.
