llr 3.8.2 released as dev-version

opyrt · 2010-09-27, 08:22

This for those of you who only read the PSP forum here at mersenneforum: George Woltman has released a new version of gwnum (26.2) with a lot of speedups. Jean Penné has compiled a development version of llr (3.8.2) with the new gwnum library.

I'm currently testing this. If everything seems OK, and I get a little help from runesk, we'll have updated clients quite soon here:

is going to be released in a week or two. Why not wait until then?

opyrt · 2010-09-27, 10:44

Good point. :)

Although, we will have to wait for Jean Penné to compile a new llr too.

JP was quick to get this latest one out. It is an "easy" update to add into everything. Some people report 15% speed increases with some machines closer to 25%. Once the next round of updates they expect better speeds still.

20% speed up on llr testing is another reason to kill the sieve.

My belive is this is not right moment to stop sieving. We are near the 10M area in LLR testing and when we go over to 10M test kandidates things will be 15-25% slower again (longer bit range). Right ?

I'm very disappointed that a new LLR is not yet available. PFGW has updated to GWNUM V26.4 which incorporates a lot of bug fixes.

Hi,

You may now download the Windows and Linux binaries of the development version 3.8.4 of LLR on my development directory :

http://jpenne.free.fr/Development/

This version is identical to 3.8.2, apart from beeing linked with gwnum V26.4

I will upload the corresponding sources when "official" gwnum V26.4 will be released by George.

Regards,
Jean

Overall I see an improvement over 3.8.0 / 3.8.1 version with one exception: 7019*10^n-1... Any ideas?

I suggest you post in this forum instead:
http://www.mersenneforum.org/forumdisplay.php?f=10

You're more likely to get attention from the right people there. :)

Bug fixes are described here.

In both Windows and Linux, LLR isn't writing a Results file, neither upon startup nor when a prime is found. I wonder if anyone else is having this problem? the lresults file is getting written all right, & I can find the primes by grepping for a !, but it would be nice to have the results file.

Thanks,
