mfaktc: a CUDA program for Mersenne prefactoring

If nothing else, MISFIT performs this function in Windows. On GPU72 there is a section on spiders chalsall wrote to fetch (and submit?) assignments under other OS's.

I've never heard of anyone actually planning to do this.

However, in an ideal world, the mprime code that talks to PrimeNet could eventually be rewritten in Python, as well as the menu code and savefile code and all the other non-time-critical stuff. Python has a rich set of standard libraries and all of that code would become much smaller and more maintainable.

The actual number crunching code would stay in C and assembler. The gwnum code could be a module that could be called from Python, or even better, mprime could be rewritten in Cython for the best of both worlds. Cython is already widely used for scientific libraries like SciPy and pandas.

And then if the above was done, other programs like mfaktc could also be rewritten in Cython and talk directly to PrimeNet.

Certainly if mprime were being written today from scratch, that would be the logical route, rather than creating a monolithic C program. The software universe looked very different back in the mid-1990s...


PS,
If all you care about is using the Manual Results page to send your results to PrimeNet, then that's utterly trivial to automate with Python or other similar languages.

This is from the "readme.txt" file in the archive, near the bottom.

0.??
- automatic primenet interaction (Eric Christenson is working on this) <- specification draft exists; on hold, Eric doesn't want to continue his efforts. :(
- this will greatly increase usability of mfaktc....

In response to:

Evidence provided. I asked a simple question. It is not necessary to be abrasive and vulgar!

I have a python script to pull work from primenet and have been using the spider pl scripts to turn work in. Both run as cronjobs.

Restarting my space heater aka 580 for the winter. Is there anything to be gained from upgrading from CUDA 6.5 to CUDA 8.0? Is it even possible to upgrade this card to 8.0?

No.

Thanks for the quick reply, James.

I did get a 1% performance boost upgrading from 6.5 to 7.5 (in upgrading from Ubuntu 14.04 to 16.04) with my GTX 580s.
