I have a GTX 1060 6Gb. A Long WU has approximately 417 000 000 GFlops compute volume according to BOINC client. My GPU do such WU about 13 minutes=780 seconds. Then compute power equal approximately 534 000 GFlops or 534 TeraFLOPS. How is this possible?

First, BOINCs benchmarks are ridiculous. If you think they are accurate, then you must also believe your Android phone is only 4 times slower than the best Intel i7 GPU because that's what some of them report. LOL.

Second, BOINC bases everything on GFlops. This project uses ZERO GFlops. It only uses IOPS and lots of bit shifts. So, how many IOPS is your GPU rated for? Since BOINC doesn't report IOPS for GPUs, its pretty much impossible for it to estimate anthing correctly.

According to the BOINC admin tools, the collatz sieve FLOPS estimates are:
mean: 5.755704e+15
stdev: 4.083170e+15
The actual FLOPS are 0 because it doesn't do any floating point math at all.

Thank you very much
