 2012-01-30, 23:33 #1 gd_barnes     May 2007 Kansas; USA 2·5,077 Posts 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 PRPnet. Rally stats can be found at rally stats. The last few rallies, PrimeSearchTeam has been rather dominant. Let's see if we can give them a run for their money this time. Gary Primes found during the rally: Code:  prime who 695*2^1008532-1 Lennart 663*2^1009098-1 Lennart 811*2^1010419-1 Lumiukko 899*2^1010544-1 Lennart 947*2^1012854-1 Lennart 669*2^1013592-1 Lennart 691*2^1013875-1 Lennart 829*2^1017747-1 gd_barnes 727*2^1018709-1 Lennart 641*2^1018986-1 Lennart 741*2^1027639-1 Lumiukko 703*2^1031219-1 odicin 727*2^1031225-1 Lennart 783*2^1034775-1 Lennart Last fiddled with by gd_barnes on 2012-04-03 at 22:34 Reason: add primes

 2012-02-18, 08:39 #4 mdettweiler A Sunny Moo     Aug 2007 USA (GMT-5) 3×2,083 Posts 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.

I run both winXP and Win7 and they work.

Strange.

 2012-02-18, 22:38 #10 gd_barnes     May 2007 Kansas; USA 2×5,077 Posts Dave, The rally started ~3-1/2 hours ago. Is there something wrong with the rally stats at http://www.noprimeleftbehind.net/sta...ntlet_20120218? Gary

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.
