PRPNet released! - Page 10

rogue · 2009-03-01, 19:34

You can d/l PRPNet 1.0.6 from here. I'm releasing it now because I think these two changes are worth the hassle of a minor release. I highly recommend running with this new release.

Here are the changes:

Add -t and remove -b3 options when using phrot. This release requires the use of phrot 0.68 or later. Adding -t will suppress most phrot output. Removing -b3 will ensure that Proth tests are always done on numbers of the form k*2^n+1.
Fixed an issue with loading saved work when restarting as the client would re-test numbers already tested instead of finding the first one that needs to be tested.

I am still working on the next release. It is a ways off as it has many new features. Some of those features include (in no particular order):

SMTP authentication
Support for Primorial and Factorial type servers
Support of PFGW in the client, both for PRP tests for Primorials/Factorials and for a primality test of non-base 2 numbers. It will also be able to find GFN factors of Proth primes.
Server and user stats.
Add user id to the client/server.

I tried out PRPNET on windows and encountered a couple of issues.

Firstly i started the server up using an ABC format file for input no problem.
Server started up in a few seconds and handed out work to clients
Then i stopped the server and restarted it and it took an hour to restart.
The input file contained 14Ks n=20k to 1M, about 470.000 candidates.
As i say, started with -i somefile.abc all was well, it was the subsequent restart that was painful.

I did investigate a bit and it is the size of the candidates file that appears to be the problem.

After starting up, the server created a candidates file of around 13.5 MB, the input file in ABC format was around 7.5MB.
Restaring the server loads the candidates file and the server chokes on it.

With the candidates file 13.5 MB in size it took a very fast core2 an hour to restart.
With the candidates file trimmed down to 2.5MB the server took 2 minutes to start.
With a candidates file under 1MB in size the server starts up quickly.

All the time the server was starting one core was running at max.
When the server eventually starts up using the candidates file it is uses around 100MB of memory, machines i tested on had between 2GB and 8GB so there was plenty of RAM available.

Second issue was with the email enabled the server crashes as soon as the first prime is reported.
No mail gets sent, the server crashes.

I tried running 1.05 and 1.06 on a variety of hardware and this behaviour was consistent.
Also tried running on XP 32bit, vista 32 and 64bit, win 2003 server, etc but no joy.

There is a piece of code in the server that does a check to verify that there are no duplicates. I can provide a patch that addresses this issue.

As for the e-mail issue, I would need to investigate. Could you turn on debugging and send me the log?

Received. I will take a look at it this weekend.

What is the latest on possibly converting NLPB to prpnet?

Still working on it. A few days ago Rogue sent me a copy of PRPnet 2.0.1 beta, and he and I have been engaged in discussion regarding testing it since then. It looks like this release will finally be ready for prime time; once we get a working server set up and running we can start looking into phasing NPLB over to PRPnet.

Was that intentional?

LOL--actually, it wasn't! I know I've used that same pun (intentionally) a number of times in reference to similar topics, but this time I seriously didn't think of it.

Is there a rough ETA on when version 2 will be released? I see PG is working with it now. I was about to upgrade from 1.5 to 1.6 next week but if 2 is coming out in the next week or two then I might as well wait.

I might release as soon as this weekend if they don't run into any new issues.
