Spose we don't really need a separate forum section for this cos I'm on my own :lol:

Stats :unsure:

If you lead others will follow Pup :D

vaio - February 23, 2007 09:39 PM (GMT)
At least Cuz left us a nice platform to build on...........shame I'll hafta just talk to myself :lol:

vaio - February 23, 2007 09:42 PM (GMT)
I don't understand these variations.
SOB sieve kp/s speed is reading way higher than my psp sieve kp/s speed.

Thought the two would be similar.
Still gonna take me an age to get anywhere though :unsure:

vaio - February 23, 2007 10:01 PM (GMT)
Ooh, I see MG has reserved a range :)

mgpower0 - February 23, 2007 10:24 PM (GMT)
yeah just a little one to start with, just running one core, had a bit of trouble setting it up but seems to be going ok. hope they fix up the stats soon, haven't updated for 5-6 days :unsure:

vaio - February 23, 2007 10:27 PM (GMT)
That's ok cos we've done nothing :lol:

mgpower0 - February 23, 2007 10:37 PM (GMT)
:D check client this morning, had found 1 factor, decided I wouldn't submit results just yet :lol:

vaio - February 23, 2007 10:38 PM (GMT)
Spose I should try this on an AMD..........just to see how it runs? :unsure:

mgpower0 - February 23, 2007 10:44 PM (GMT)
running mine on the AMD over twice as quick as PSP sieve, wonder what would happen if you used the SOB client to run PSP :)

vaio - February 23, 2007 10:46 PM (GMT)
Confusion that's what :lol:

mgpower0 - February 23, 2007 11:02 PM (GMT)
:D I was thinking just replace the proth-sieve.exe in the PSP directory with the JJsieve client that SOB uses and maybe add a nextrange.txt file to PSP directory as well. Might give it a go :blink: maybe

mgpower0 - February 24, 2007 04:12 AM (GMT)
well so far so good, just replaced the proth client with the jjseive client and left my other files in the PSP directory the same. rate up from 306kp/s to 378kp/s. Won't know if it succeeds until I have some results to submit to PSP :)
The downside, I accidently overwrote my facts file in the SOB sieve folder and had to restart the range again. opps :lol:



edit- thats strange, no performance increase at all on the core2 only on AMD

vaio - February 25, 2007 12:15 PM (GMT)
I get around 900 kp/s.........yet with riesel sieve I get under 100 :blink:

Just running this on and off in trickles at the moment cos I'm trying to help boost the pi team........plus I only got one rig that's any good on it. :blink:

mgpower0 - February 27, 2007 11:47 PM (GMT)
might have to give that riesel sieve a go ;)

vaio - September 15, 2007 10:39 PM (GMT)
Nice 110 point gain at the vault......way to go B)

vaio - October 8, 2007 02:02 AM (GMT)
I see Charles and MG are keeping us ticking along here :)

vaio - October 12, 2007 02:25 PM (GMT)
Next overtake in 44 days. :)

The newer versions of JJsieve were much faster, but SR2sieve is faster than even the last released version of JJsieve.
Head on over to: http://www.geocities.com/g_w_reynolds/sr2sieve/ and pick up the latest version of SR2sieve.
There are Linux (32bit and 64bit), Windows (32bit and 64bit), and OSX versions available.
There is also now a way to drop SR2sieve in as an almost compatible replacement for JJsieve:

QUOTE (geoff;116725)
sr2sieve 1.6.10 has a new -j switch that will make it behave in a similar way to JJsieve or proth_sieve, for compatibility with Sobistrator. Checkpoints are written to SoBStatus.dat, ranges are read from nextrange.txt.

It should be possible to start a range with JJsieve and continue it with `sr2sieve -j -s', and vice versa.

I haven't actually tested it with Sobistrator though, so let me know if there are any problems.


Let us know what your speed improvement is after you upgrade.

There is also a new dat file available for combined (PSP and SoB) sieving:

http://www.psp-project.de/test/sievecomb.zip

This dat file reflects the newly found prime for k=33661 and all submitted factors.

RieselSieve also has a recently released new dat file at: http://www.rieselsieve.com/dload.php

vaio - November 15, 2007 06:39 PM (GMT)
We could do with a few Intel machines to boost this..........we could do with getting some more points on it :unsure:

91 days from an overtake.

Would be nice to make top 70. :blink:
