[QUOTE=Xentar;90566]Just found version 1.3.3 on the server.
Could you please tell us, what´s new in this version?[/QUOTE]
The only change in version 1.3.3 is that the number of found factors is written to the log file when the range is finished.

cool, no need to open the file with excel now ...:smile:

notepad is more memory friendly ... and less blue screener :sick:

sr5sieve 1.3.4
 

A small change to the hashtable code makes it 3% faster for P2/P3, 1% faster for P4.

1.3.4 with newest .dat file:
83k p/s
It´s getting faster and faster :smile:

sr5sieve 1.4.0, srsieve 0.6.0, bug fix.
 

These versions fix a serious bug in the i386 assembler 64-bit modular arithmetic functions that could cause some factors larger than 2^46 to be missed. All previous versions were affected by this bug. (But not the PPC or x86-64 variants). Luckily the distributed sieve has not yet reached 2^42, so no work needs to be repeated.

I have completely re-written the mulmod64() and powmod64() functions and tested them against GMP for random primes up to 2^62 (2^52 for non-assembler versions). For those who compile from source and have the GMP library installed, there is a 'srtest' program that will do these tests.

And the new version is 5 - 7% faster, nice :smile:

What type of machine is that result for?

On my P3 there is not much difference in speed between 1.3.4 and 1.4.0, 1% faster at most, but I found my P4/Celeron is about 7% faster.

Using a Core 2 Duo.
At the moment, it runs with 87k p/s (per core).

Around 7% improvement in my P-M (went from 44.5 to 47.5)

On Athlon 64-x2 around 0.5-1% faster

sr5sieve 1.4.2
 

This version is about 10% faster on my P3 and 15% faster on my P4 Celeron compared to 1.4.0, mainly from improving the FPU instruction scheduling in the new mulmod/powmod code.
