  1. There are plenty of short GFN tasks which would have been suitable for GPUs in the pool. On most GPUs, such tasks can be completed in 2 to 30 minutes and that's approximately in the area of PPS Sieve tasks. The scary stuff Michael described before is not an exaggeration, but I have experienced it only with the longest GFN-22 tasks which can run for days. Users can select between various GFN tasks in their PrimeGrid preferences, so our pool admin could have done the same. The only problem is, short GFN tasks yield very little credits (far less than PPS Sieve) and that makes them unattractive for Gridcoin. However, with more credits, pool users would have been happy to crunch them - Primegrid's GFN output would increase at least threefold, yielding many new generalized Fermat primes. Unfortunately, with Gridcoin incentive removed, that's just a hypothetical scenario now.
  2. Michael, we are 'rank and file' PrimeGrid users here. We post here and we post on PrimeGrid forums and we have been doing so for years, there is no 'us' against 'them'. I am with Primegrid since 2011, I was with many teams before I joined team Gridcoin in 2015. I have discovered 8 new primes and I have donated to the project, both in EUR and in GRC. I could have mined almost any other Bitcoin-like cryptocurrency out there and I would have probably made 10x more money, but I wanted to discover those primes and I still do. Is my 'balance sheet' also in the negative on your books?
  3. Expanding on the previously posted "Gridcoin 2019 Budget", I created a New Marketing Initiative for Gridcoin which I believe could help us regain some of the value we lost during 2018. Counting on your support. New Marketing Initiative for Gridcoin — Steemit With 2019 approaching, it's again time for Gridcoin community to decide and vote on our marketing efforts for the next… by vortac

    Things have indeed changed a lot, competition is a lot tougher now. A single 280X might yield 9-10 GRC per day now (in [email protected]).
  6. Hey guys, thanks for reading my stuff, glad to be of help. Indeed, if you are looking for best "mag for bucks" ratio, crunching [email protected] with some old Radeons is probably still the best way to go. HD7970 are still no.1 there for FP64 and they are quite cheap, if you can find them (eBay etc). Other than that, if you are going the FP32 way, looks like Nvidia GTX 1060/1070s are still the best buy.
  7. Support Gridcoin Joint Marketing Initiative for the next year! https://steemit.com/gridcoin/@vortac/gridcoin-joint-marketing-initiative-2018
  8. I am going to vote for Rob's proposal. I think it's the most complete proposal we currently have. It's not perfect, but as Quez says, a good plan now is better than a perfect plan next year. However, this discussion is very technical and many community members are probably reluctant to voice their opinions, since they don't fully understand all the details. Not to mention that CCT, which was our main channel of communication not so long ago, has become less important today, with Slack, Discord, Steemit and other platforms which are now available.

    Hail The Moo Master :)
  10. HD6970 has 2.7 TFLOPS in FP32 (Collatz) and 0.6 TFLOPS in FP64 (Milkyway). Most likely, it will yield more GRC in Collatz, but not a big difference, 0.6 TFLOPS is more than enough for Milkyway too.

    Yes, original Titans have better FP64 performance on paper, but for [email protected], users reported worse performance than with HD7970: http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=4171 Similar thing with FirePro cards. In this very thread (page 2), user boristsybin reported FirePro W8100 (top host #9) having roughly equal performance in Milkyway as HD7970, although specs for W8100 show 2.1 TFLOPS in FP64.

    Nvidia Kepler and Maxwell GPUs have FP64 performance capped at 1/24 and 1/32 respectively, they are an absolutely disastrous choice for [email protected] Hawaii GPUs are capped at 1/8 - better, but still far worse than Tahitis (which are 1/4). Original TITAN and TITAN Black GPUs have very good FP64 performance (at least on paper) but they still perform worse than Tahitis (OpenCL issues of some kind, most likely). Only one glance at http://milkyway.cs.rpi.edu/milkyway/top_hosts.php will tell you that Titan, Kepler, Maxwell and Hawaii based cards are nowhere to be seen.

    Well, Gridcoin was indeed worth approximately 5 times more at the peak in June :) Other than waiting for the next peak, there's not much more that you can do. Pool feels are very small, switching to solo makes very little difference.

    Checked your host, I think you are doing OK, 30-35 GRC daily is an expected payout with your RAC. Of course, it's a little bit disappointing seeing those FirePros behind 7970s, but professional GPUs are often underutilized with BOINC apps. Users reported similar situation with Titan Blacks: http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=4171

    Looking at those numbers, I would say that host 736335 is most likely running 6 tasks in parallel. All top hosts are running many tasks on one GPU, in order to increase BOINC output and earn more BOINC credits. For more details, you can study this Steemit article (look under 3.
