Sean2002 breaks the SETI 2 Hour Mark!

[LiveLongAndProsper]

Sean2002 rig according to Sean:

Giga-Byte 8IHXP
Pentium 4 Northwood 2.26Ghz
512MB Kingston PC-1066 RAMBUS
Western Digital WD1200JB
Ati Radeon 8500 128MB
Sound Blaster Audigy
Antec plus830 case with true power 430 watt.
48X12X48 Lite-On CD-RW
16X Lite-On DVD drive
Samsung 900NF
Logitech Z560's

I'm running this at 2.58Ghz using a 152Mhz (608Mhz QDR) FSB.

I think it's the RAMBUS frequency 1212Mhz that makes seti fly.

Does anyone have a guess on how a P4 2.4 running on an i845E board, overclocked to 2.8-2.9 range(about 160mhz FSB), will do?

Awesome rig!:Q& congrats on being the 1st to break the 2hr/Wu barrier!

Btw what times do you get on 0.417 AR WU's?

 

[BadThad]

I think have quite a few wu's under 2 hours now on my main rig...will check when I get home. P4 2.0a@2640 with ram at 351MHz DDR CAS2-2-2 settings....my avg is 2:43 now, up a hair from 2:40 I had at first. This system is a solid 8 wu's/day machine even with gaming and general usage (I do turn it off while gaming tho).

Keep 'em coming!

 

[hamburglar]

wow that's fast!

 

[dakarm]

how do you calculate how many WU/day you do?

is there any way to look that up?

I'm crunching 2 processes at a time and it takes my SuperServer about 4hr 30min to complete 2.
I'm also thinking of upping the processes crunched to 3 from 2 since have plenty of CPU utilization left. It's currently running about 70~75%. Even with folding@home running on the same machine.



So does that mean about it's about 10WU per day? also how do you check the AR and HAR and such?

One way to calculate is take your WU time, say 4 hours. Take the number of hours in a day, 24 (normally ) and then do the math!

24 / 4 = 6.

So a machine doing a WU in 4 hours would turn out 6 WUs a day. If you have more machines, then figure out how many per day they do, and just add the results together.

So if i'm crunching 2 processes at the same time then it would be 12?

I bumped the processes to 3 and cpu utilization is now at 100% but the system still responds well, ie, I can still surf, etc. I'm guessing it's because I have a whole another processor doing nothing in the server. how do I run multiple instances of the CLI?

is it just a matter of installing the CLI in a different folder or do I need to change anything else? If I can use the second CPU I'm thinking I can get this system up to 24WU/day or more.

Yes, it would be 12 per day, assuming you had 2 CPUs that could do 6 per day. However if you have one CPU then no, because you would be giving the chip twice the work to do, therefore it would take twice as long.

First off, processes = instances. You should set processes to the number of CPUs you have.

Running multiple processes on single CPU systems yeilds no output advantage.

Follow this:

1) System crunches one WU at a time, and it takes 4 hours to complete the 'cycle'. 6 WUs a day.

2) System crunches two WUs at a time, and therefore it takes 8 hours to complete a 'cycle'. 6 WUs a day.

See? Now assuming you have a single CPU, you should only be running one 'process' and one 'instance'.


A): The only situation where you would run more than 1 process in SETI driver is with multiple CPUs

B): The only situation where you would run multiple instances of SETI driver is where you might want to crunch for two accounts and therefore divide the proccessor power between the accounts.



Since you have 2 CPUs, you should set your processes to 2.

how do I run multiple instances of the CLI?

Easiest way is to run Setidriver ,go to the upper link in my sig & you'll see a link in there for it

WOW!
