@rogue: Do you have a guide how much VRAM will be used for x sequences with the srsieve2cl?

For now avoid using -W with srsieve2cl. By default it will use -W0 and -G1. It will use the CPU for testing until p > 1e6 then switch to the GPU.
Thats a puzzle, shouldnt it start at p=37G in stead of p=0?

Good you figured it out.

If you didn't provide -p on the command line and it isn't in the input file, it will start at p=0. Did I misunderstand your question?

The code does capture the number of bytes it allocates in GPU memory needed for kernel arguments. I could modify the code to print that out when using -H.

Maybe I wasn't clear, I'm having too many balls in the air at the moment and the building of my 2 new machines turned out due to a human error (made by me) to be far more than a walk in the park.

The question was, as you could see in my copy paste of CMD prompt window of what in fact happens, that I used this flag "-p 37684705039" and therefor that should be the starting value of p, but it appears that srsieve2cl still started at p=0, is that correct or did I missread the outputs that was printed on the screen? ... Does the use of -W x somehow interfere with the -p setting?

The issue is with -W in srsieve2cl. If you remove -W and have a single GPU worker and you only see p=0, then there could be a problem.

I added all of results again, since i dont realy know when i posted an update on it.
