PRPnet 2nd drive51 bases with <= 5 k's to n=250K
This is CRUS PRPnet team drive #2 for all bases <= 200 with <= 5 k's remaining. We will be testing all k's to n=250K or until primed. Included in the drive are 51 bases and we may include more as bases are released or more bases are found with <= 5 k's remaining. The bases have each been sieved to their optimum depth for testing up to n=250K.
We will be running the drive entirely on CRUS PRPnet server port 1400. The server will hand out work by nvalue so several bases will not be tested until we reach n=150K or 200K. Instructions for running a PRPnet server and download links can be found here. The info. specific to this server that needs to be entered into your prpclient.ini file is: server=G1400:100:1:noprimeleftbehind.net:1400 Server info.: CRUS PRPnet server #2 (updated 20130812 02:30 GMT): maintained by mdettweiler on gd_barnes machine Short identification: G1400 server: noprimeleftbehind.net port: 1400 51 bases <= 200 with <= 5 k's remaining to n=250K nrange: 50K250K currently processing at n= 250K (complete) Server summary: http://noprimeleftbehind.net:1400/all.html Primes: Code:

All four n=50K bases have now been loaded into the server for a total of 22 bases. It's off to the races now!

Wow, what a run after a slow start.
I wonder why the clients only proved 2 out of the 5 PRP's? Mark, do you have any thoughts on that? Last fiddled with by gd_barnes on 20110804 at 19:10

Until then, can someone tell me which were not proven and which program was used to determine that they are PRP? There are some possibilities, which might account for that. 1) Running LLR only, but LLR can't prove primality due to running an older version of LLR. 2) Running LLR only with current LLR, but PRPNet client is incorrectly parsing the LLR output. 3) Running phrot on nonx86 computer as phrot can't prove primality. 4) Running phrot on x86 computer as pfgw and llr are not available. 5) Running pfgw, but primality test fails (least likely cause).

Note that if running on a 64bit OS that 64bit pfgw is much faster than 32bit llr for nonpower of 2 bases. By much faster I mean more than 1 or 2 percent. pfgw can be 10 percent or more faster than llr, depending upon various factors. I understand that a separate primality test will be needed if a PRP is found, but since so few primality tests are needed (less than 1 in 1000), it is far better to use pfgw on a 64bit OS. Now if they are all on 32bit OS's then 32bit llr is better than 32bit pfgw.
