If you are an owner of a RTX3080/90 card and can run mfaktc pls post the results running in standalone:

run mfaktc.exe --perftest

At the moment the current mfaktc version is not running on RTX3080/90, trying to get a cuda11 version for testing.

A linux version is ready for testing in standalone, the cuda11 lib is also in the zip file.

Pls try to run it on RTX3080/90 and older cards with

./mfaktc.exe --perftest

which value shall worktodo.txt have?

which value shall worktodo.txt have?

o.k., thanks. With this number the result is:
no factor for M219111587 from 2^70 to 2^71 [mfaktc 0.21 barrett76_mul32_gs]

Will there be a windows (test) version soon?

http://srbase.my-firewall.org/sr5/download/mfaktc-linux64-cuda11.zip -->Linux cuda11.0

http://srbase.my-firewall.org/sr5/download/mfaktc_3xxx_11.1.zip -->Linux cuda11.1

Will there be a windows (test) version soon?

yes

Any estimate?

There is a new win version to test, give it a try.

http://srbase.my-firewall.org/sr5/download/mfaktc-0.2.1.win.cuda11.2.zip

mfaktc-win-64.exe -h:

The code execution cannot proceed because cudart64_110.dll was not found.

mfaktc-win-64.exe -h:

The code execution cannot proceed because cudart64_110.dll was not found.

Is the file included in the driver installation or toolkit?

The file is in cuda_11.2.2_461.33_win10, but Visual studio was needed for it's installation (according a warning)

Windows Version + plan_class are done. Lets see how its working with wrapper from mfakto

Update:

The first wrapper doesnt match with the one in download folder, gave some download errors, fixed in v16

Update2:
Doesnt work, same error, need more testing with wrapper.

Update3:
The v12 cuda app is using an older wrapper, will setup this with v15

Update4:
added min_nvidia_compcap to plan_class_spec because of older cards with latest drivers and toolkit (doesnt work with cuda11.2 app)

Special Thx to lolapus who has compiled the app!
