    So is that these tasks?

    Yes, one host is getting those mostly along with the FGRPB1G tasks.  The other host is getting mostly the FGRPB1G tasks and a smattering of GW 2.07 gpu task.

    This host has a lot of the Velajr1 tasks in Pending and awaiting a wingman with a 1 Jan 1970 sent date.

    https://einsteinathome.org/host/12444941/tasks/2/54

    Or it did earlier.  Looks like I have a wingmen for those tasks finally.  The scheduler must have crawled through the pendings and sent out for wingmen since my last post.

I'm also on a Team and trying not to pass my Teammates, just because I can, so that adds into things too. I will pass them if they quit a Project but not if  they are actively crunching it, I believe in the axiom 'just because you can doesn't mean you should'.

      Agreed, apart from the teammate thing, I don't get why you wouldn't want to pass them.  A team in formula 1 could have one driver passing another.  If one can win the race and beat other teams, then they have to pass the rest of their own team first.

      Oh I could easily pass any of them but that's not being a good TEAMmate, they earned their spot at that Project and why should I knock them off it just because I can. One teammate had over 20 million at one project while I had 3.5 million, 3 weeks later I had over 10 million and stopped. I did pass another teammate at another project during a challenge but then stopped and let him pas me back again after it was over, I passed him in under 4 days. At Collatz if I put every gpu I  have on it I get close to to 60 million credits per day.

      PS i also like F1!!!

      Well in most races you can help your teammates, but there's no way you can do that here.  So apart from stopping processing for a bit (which isn't good for the science), I don't see how you can not pass them.  Unless you just work for another project?

      Anyway isn't the point of a team to achieve as much as you can collectively?  So what if you do more than them?  If you really want to help them out, post one of your GPUs to them :-)

        I can give you two an hour but that's it, but Einstein keeps handing out gamma for some reason.  The server status shows crazy amounts of gravity waiting.  Maybe they consider gamma more important?

          I have fired up my Windows 10 box with its gpu pointed only at GW.  

          I expect to have an AMD video card show in the next couple of days.  I will look back and see if I can get the gpu/task segmentation to work so it is pumping out GW tasks.

          I have also switched back to pure gpu processing on both tasks (GW/Pulsar) on my Amd 3950x but who knows if/when it will download anything...

          Anyway, Windows with a pretty dinky Nvidia is running under 20min per task.  On the 3950x it is looking like near 12 hours for the CPU version of GW (it was an experiment, is running on 1 thread).

            Calling all volunteers! Now is the time to jump into GW GPU crunching because the current batch of GW GPU VelaJr1 tasks can be run rather quickly.  An RX570 at 3x (gpu utilization factor of 0.33) has average task times of 11 to 9 minutes, while a GTX-1080 or RTX-2080 can get one done in 7-8 min. As discussed in that linked forum, a paucity of hosts running those tasks is resulting in those that are not (yet) being assigned a wingman to provide a quorum of two to validate the tasks. At least that's the case for me with my growing "Pending" list.

            What have you done to get them crunch that quickly? I have two concurrent GW GPU VelaJr1 tasks, each always takes around 25 minutes to be completed. Have you raised the amount of assisting CPUs? Currently, I have 0.9 CPUs + 0,5 AMD GPUs. According to the AMD driver my card has a workload of 60-70%. Overall CPU load is at 25% in average.

              HA! Well, that speed spurt didn't last long. I just checked and those VelaJr1 tasks are now taking ~24 minutes. I guess the short tasks at the magic frequency were a "limited time offer" that I thought would last longer than it did. My CPU utilization is set to 0.5, but that doesn't affect CPU usage or thread allocation.  I can't recall why I set it to 0.5 from the default 0.9, but I'm sure I had a good reason at the time. LOL "If it ain't broke don't fix it", so I'll leave it at that setting for now.

              Ideas are not fixed, nor should they be; we live in model-dependent reality.

                I gave up with that usage thing, and set all GPU tasks to request 0.01 CPU cores (0 seems to have hidden meaning).  Then I use the "use at most x% of the processors" in the basic Boinc settings.  Something to do with LHC's multiple CPU core tasks (Atlas).  I think what happened was since I had the computer set to use all 6 cores, minus whatever the Einstein GPU tasks subtracted, LHC still gave me 6 core Atlas tasks (a failing of Boinc), so Einstein kept getting throttled.  I just worked out the most CPU cores that would be needed for GPU work, and removed them permanently.

                  So... watch my back, I'm going in.

                  I just received (hopefully) the last lockdown buster from eBay today. A low power i7-8700 to run a new MSI mining board. The 12 core 8700s are going for just a little more than the 8 core 6700s, and the board is going for $60. I decided it would be worth it to be able to run 12 GPUs again. I was running 14 GPUs on a 6700 at SETI, but the SETi App is happy with just Half a CPU core, unlike this place. The afternoon test shows a big improvement on the Gravity App, not so much on the Gamma App. I was just testing with a single GTX970, I'm now going to swap out the new board with the one running the 8 higher end nVidias. Hopefully it will only take an hour or two...

                      I have sent my older gpu's to my teammates, I've also sold and given my pc's to teammates as well when they needed them.
