PRPnet rally Feb. 18th-25th
 
Hi everyone,

After a nearly 10 month absence of rallies, we figured it's time to have another. The rally will begin Saturday, Feb. 18 at 7 PM GMT and finish 168 hours later on Sat., Feb. 25 at 7 PM GMT. That is 2 PM EST and 1 PM CST in the U.S.

This time for the first time, the rally will solely be a PRPnet rally as NPLB continues its transition to mostly PRPnet servers. It will be focusing on our 14th drive, that is k=600-1001 for n>1M, in order for the range to play "catch up" with our 13th drive. That means PRPnet port 2000, which should be in the vicinity of n=1.01M-1.04M during the rally. A prime at that level should come in around 1000th-1500th place in the top-5000 list.

PRPnet config info.:
server = "www.noprimeleftbehind.net"
port = 2000

Or, in terms of a prpclient.ini config line:
server=G2000:100:1:noprimeleftbehind.net:2000

Be sure and change your userID to whatever ID you prefer. Most people use their ID here at mersenneforum. It is also best to set the cache to something in the vicinity of 2 to 10 pairs.

Info. for downloading the newest PRPnet client can be found at [URL="http://www.mersenneforum.org/showthread.php?t=12223"][COLOR=#000080]PRPnet[/COLOR][/URL].

The last few rallies, PrimeSearchTeam has been rather dominant. Let's see if we can give them a run for their money this time.

The rally starts in just over 12 hours. Come one come all to port 2000! :smile:

I just moved all of my machines over to port 2000 that weren't already there--they should all be on within a couple hours as they finish their current workloads.

This should (hopefully) be a record rally for me--I lost two machines' worth of firepower but more than made up for it by adding two others that are more powerful. My venerable Q6600, long the linchpin of my computational arsenal, kicked the bucket in early December (probably CPU failure--it became extremely unstable at the end) and was replaced by an i5-2400, which in addition to being twice as fast as the Q6600 on a per-core basis to begin with, can take advantage of the AVX speedups in recent pre-release LLR versions for an additional 50% speedup. I also dropped a Phenom 9750 on extended loan from Gary which has now been "returned" to him, but in turn added an i7-2620M (dual core) tablet PC laptop which, like the i5, is 250% faster per-core than a Core 2, for a net throughput slightly greater than what the Q6600 produced. That, plus a Phenom II X4 N970 that I've had for a little while (but not as far back as the last rally) and my old E4500 dualcore should put me consistently over 50-60 tests/hour on port 2000. :cool:

I shall try to keep up with you :smile:

I also will be in with nearly all cores... but Lennarts firepower is amazing, I seen in other races ;)

Is this only for Linux hosts? None of my 6 Win hosts (1 Win 2003 server X64, 2 WinXP x86, 3 Win7 x64) can get any work from noprimeleftbehind.net:

Hi! Welcome to PrimeGrid's PPSE Low n server.
Starting Proth prime test of 7053*2^323120+1

I have tried also other ports (in noprimeleftbehind.net) with no success.

Pinging noprimeleftbehind.net works OK.
Disabling firewall did not help.
My Linux host is getting work fine.

I run both winXP and Win7 and they work.

Strange.

Win, Mac, and Linux hosts should all work.

gd_barnes 2012-02-18 22:38

Dave,

The rally started ~3-1/2 hours ago. Is there something wrong with the rally stats at [URL]http://www.noprimeleftbehind.net/stats/index.php?content=gauntlet_20120218[/URL]?

Found the reason, it was not the Win firewall but my HW-firewall. Now I just need to figure out why, and how to configure it to let this traffic through.
