Hi, I'm Mihai Preda the author of GpuOwl/PRPLL [1], an OpenCL software used by Luke Durant for his recent discovery of the largest prime number know, the 52nd Mersenne prime 2^136279841 - 1 [2].
Feel free to ask questions about technical aspects of the GpuOwl implementation, about optimizations, tricks, efficient FFT implementation on GPUs etc. Or anything else.
