Default Proth 2.0

On Discord Primegrid channel Yves announce Proth2.0
This is OpenCL GPU version for searching ONLY candidates on base 2 and plus 1 ( k*2^n+1)

There is lot of work to do, but even now it is fully functional and very fast app.
I run it over night and found two small primes ( 43000 digits)

Cool. I'll have to make some changes to get this to build on OS X, but I'll give it is spin once I do that.

I have good news and bad news. It complies cleanly on OS X and runs correctly using the NVIDIA GPU. The bad news is that it does not run correctly on the AMD GPU. I have submitted a bug report to Apple as I suspect the driver is buggy. This isn't the first time I have reported a bug like this to Apple and they were fairly good as fixing the last one.

Out of curiosity, but how much of a gamechanger will this be able to be to our base 2 sierpinski conjectures?

So eventually PrimeGrid will be seeing GPU primality testing apps?

Communications and data management, mostly. The software as it exists accepts and produces local data; something has to be written to grab input data from the project and send results back.
