LLR version 4.0.0 released.

Jean Penné · 2021-06-25, 15:15

Hi All,

I uploaded today the version 4.0.0 of the LLR program.
You can find it now on my personal site :

http://jpenne.free.fr/

The 32bit Windows and Linux compressed binaries are available as usual.
The Linux 64bit binaries are released here, and also the Mac OS 64bit binaries.
The Mac OS 32bit is not released here because I have not the 32bit hwloc library which is needed, and could not build it on my Mac mini...
I uploaded also the complete source in a compressed file ; it may be used to build the 64bit Windows binaries.

What is new in this version :

It is linked with the last version 30.6 of George Woltman's gwnum library.
No really new feature, from 3.8.24, but some improvements related to reliability and speed.
I avoid now the use of giants functions invg() and gcdg() which are slow and seem not to be very reliable.
To do that, I am using gtompz() and mpztog() conversion functions.
Also, I replaced everywhere the gwnum squaring and multiplication functions gwsquare() and gwmul() by their new forms :
gwsquare2(), gwmul3(), gwmul3_carefully(), etc...
As usual, I need help to build the 64bit Windows binaries.
I uploaded also the GNU gmp6.1.0 compressed source I used on 32bit VC6.0
I hope it can be used to build this library on Windows 64bit and link it with LLR...
Please, inform me if you encountered any problem while using this new version.
Best Regards,
Jean

Thanks for the long-needed major version bump!

Can someone actually post a 64-bit Windows build this time? I've been running the 32-bit cllr 3.8.24 on my old laptop since it's not well-suited to run Visual Studio.

Can you elaborate a bit? What sorts of speed improvements should we see, on which architecture(s), and is it for numbers of a particular form, etc?

In some limited testing, I have not observed a speedup.
