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.

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.

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?

I figured out why this is happening. It will be fixed in then next release.

For now avoid using -W with srsieve2cl. By default it will use -W0 and -G1. It will use the CPU for testing until p >...

I only have one machine that can sieve 4000 or so sequences (enough for a 1G range of R3) in the GPU. I just kicked off the 36G range.

Since I will be using PRPNet to manage the testing, I can...

Now you tell me! :-)

15 seconds is the time for a single test on this laptop at n=80000.

I'll switch over to testing the range.

twinsieve is "fixed n and variable k" and the srsieve programs are "fixed k and variable n". They require completely different logic.

In theory if one has a very small range of n, then twinsieve...

117*412^294963+1 is prime. It is 771300 digits long. It has been a while since I've added one to the Top 5000. This conjecture is down to 2 ks. I'm still searching.

All I can say is that the output is telling me that the CPUs are not being fully utilized by twinsieve, unless there is a bug causing the CPU to burn cycle without doing anything useful.
