Did you use default qmin? I think it’s 4e7 (or 4e8) by default, but I left it alone for this run.

qmin doesn't affect poly select, since it merely tells the siever what Qvalue to begin at. I think I changed it to 10M anyway. I did set sieve params to values I might choose for a testsieve, so your CADO score will be different from mine (but cownoise fixes that for us).
If you add tasks.sieve.run=false to the command line, CADO will exit after poly select without building factor base/starting to sieve.

break Do you have any feel for CADO’s deg = 5 performance? IIRC, one gets better deg = 5 results with msieveGPU correct? I’m estimating a minimum search range of 35M < c5 < 55M for msieveGPU but that’s based on extrapolating my results to date so take that estimate with a grain of salt. I have yet to run any msieveGPU poly search for this c217 though I hope to start early in 2020 after finishing my current HCN efforts. Last fiddled with by swellman on 20191222 at 23:52

I think they're competitive in degree 5; I won't talk folks out of using msievegpu, but when my CUDA install broke last spring I didn't bother fixing it and just shifted to using CADO for all my personal polyselect needs. If I had a GPU faster than a 750ti, I imagine I'd still be putting effort into using msieve.

I'll do a deg 6 poly search for this on CADO, with admin = 5e6, admax = 5.5e6 and P = 16e6 after I finish 47771_188.

I just realized I also have to finish an msieve matrix for NFS@Home as well, so I'm cancelling my run.

3e6 to 5e6 on CADO deg 6 complete. Best poly is underwhelming:
