New Folding Machines

Well after about 2.5 months of folding on an old 1.4ghz thunderbird, which may be the slowest machine I have ever seen (it takes about 33 hours for a single work unit), I finally have been able to dedicate a couple new computers to the cause, though I don't know for how long. The old machine was only able to run about 60 WUs in the time it was up.

The first new machine's eventual role will be an imaging server. It is a dual Opteron 248 (2.2ghz), with 4GB of Corsair XMS PC3200 ECC-Reg'd memory, a 2 x 120gb OS drive, and 5 x 36.7gb Seagate Cheetah 10krpm hot-swappable data drives in a RAID 5 configuration, running Debian Linux (Sarge). Most of that, of course, is completely unnecessary for f@h's requirements. F@H is currently running 1 CPU at 100%. It seems to be able to do a single WU in about 5 hours.

The second machine is just a workstation that I am "burning in" for the foreseeable future. It is a Pentium 4E 3.2GHz running on an Abit IC7-Max3, 1GB of Corsair XMS PC3200, and 2 x 36.4GB Raptor SATA drives, mirrored, running Windows XP Professional SP2. I have not checked on it to see how fast it could do a single WU.

Anyways, that's all. I just thought you guys might be interested.

Run two instances of folding on that Dual Opteron, and even on the P4 3.2E.

Not putting that second CPU to use is a horrible waste, and it won't affect your performance.
 
I'm assuming you'll be folding for 33, or are you just dangling this in front of us?

Anyway, nice computers. You going to run two clients on the dual opteron?
 
Hey man, some of us still use a 1.4GHz tbird as our primary machine! :D

ok ok, so its overclocked to 1.4GHz. :rolleyes: :p

Bah, try running it on some P3 600's. Takes 4-5 days, heh BUT IT ALL COUNTS!!!
 
Yes they are all folding for number 33.

I was thinking about running 2 clients on the Opteron, but I decided against it. The other guys are using the box for some odds-and-ends and I don't want hog all of the CPU(s) time.

xENo: I have seen some MUCH faster Tbird boxes than this POS. I used to use one as my gaming machine. This one, though, is just terribly slow. Its a frankentein box. It has this terribly old Soyo KM266 motherboard and some ultra-slow PC100 SDRAM in it. It really is pretty awful, but its just a web server and a folding box, so I'm not really interested in tweaking or upgrading it.
 
Maybe you could still add a second client, but drop one of them down to 75% or something. That way you can be sure that you'll get enough cpu for whatever business-related tasks you may need to do.

 
Unless the other guys are running some other DC project then run two clients on a dual cpu box.

What you will find will two clients running is either .......
One will vitually shut down, cpu time from 100% to 10%, and the other runs at about full speed, around 90%.
Or
Both will slow down to around 50%.
Which pattern they follow depends on how well the primary task multi-threads.

Luck.......:D
 
"odds and ends" ?? have you checked out the performance hit? unless they are also doing DC or maybe a broken compiler :D there shouldn't be a hit to speak of. IF you can spare the RAM... run it with the "accept Wu bigger than 5mb" option to YES... double the points. I run one set to yes and one set to no on a friends 2.8 HT.

very nice borgs indeed. keep it up.

well this server runs an image database...its not in production use right now, but a couple of the guys are writing some software that touches it. its a pretty hefty database. it contains every page of every fax that comes into the office on a daily basis (around 2500 pages or so). it isnt really just pulling from and pushing into the db. there is also a lot of image manipulation (a la GraphicsMagick) that happens, which uses a LOT of ram and a pretty fair amount of CPU.

while there is normall no performance hit with one of the processors utilized for f@h, there is a pretty considerable knock when running one on each CPU...

I think it also is a part of our drb (distributed ruby) project.

There shouldn't be a hit, unless you set the FAH program to run higher than idle, or someone set one of the daemons to be idle priority, which is insane.
 
Well I installed the second client on the dual opteron and nobody has complained yet....
So now there are 2 clients running 100% each.

Good stuff.
