I wonder why the people who quit are not detaching from the project. What I have read from the scheduler source suggests that doing that would release all the work to be sent to others. Ghosts too.


. . That would make it a good practice but I am guessing no-one passed that knowledge on to the rank and file volunteers, I had certainly not heard it before though it does make perfect sense.

Yep, so far 2020 has been hell around here. First, my favorite Cat died in January. In mid-February my 90 year old Bed-bound Dad died of something that fit all the symptoms of the Chinese virus. Of course, back then they weren't testing anyone for the Virus, especially if you had been in Hospice for over a year and Bed-bound. Then in March SETI died. I'm dreading April. The only Good thing that happened was no one in direct contact with my Dad has turned up ill...that I know of, and I'm finally receiving Social Security checks. Big changes. I suddenly have this overwhelming sense of Freedom. I'm not quite sure what to do with it yet, maybe I'll come up with a plan once all the paranoia ends. I'm perfectly healthy, and apparently have stared the evil in it's eye and held it's hand. Now if I could just find some TP in one of the stores...


. . It has been a bi^&h of a year here too, drought, massive bushfires then flooding. My dad died years ago but it is a hard time to get through, and the adopted stray cat that I was feeding disappeared about the time of S@H ending. Can't say I am feeling much freedom though. But otherwise I can sympathise with the battle against the blue meanies.

Perhaps we should all set up a new team called Seti Orphans, and go invade another project.. ? :-)

I like such idea! Maybe on different projects but the same team, SETI Orphans :)
Would be the honour to participate !
P.S. my personal choice would be Einstein@home as closest in spirit one.
Will see if it can feed all my different devices. Not compatible ones will search for new targets...


. . It would be an honour to follow :)

The trick to managing work at E@H is to set a really, really small cache. Like 0.1days. Then you basically run on a "turn one in - get one" schedule.

. . I set their resource share to 0% and get one for one without changing cache settings.

Hi,
Einstein seems to have open source code and it uses 45-88% GPU on my system.
Seems like it could need some optimizing. But but,... if it is OpenCL then I'd have to turn it to CUDA first ...

Hi petri, keep in mind they have two different types of tasks there, the low GPU utilized tasks must be the Gravity Wave task. it requires a lot of spare CPU support. I've seen 150% CPU thread per GPU. The Gamma Ray tasks pull only 100% CPU thread and have good 98% GPU utilization.
I would love to see if optimizations are possible there! tilt the scales back towards the nvidia cards :). as it stands, the project heavily favors AMD cards.


. . Hey, if this happens I might turn my 2 * GTX970 and 2 * GTX1060 rigs back on :) Those rigs have enough CPU threads to support both GPUs.

Einstein will do the same if you give it a small resource share, because it has a 7 day deadline. It insists on filling up to your cache size, then doesn't run for 5 days or so then panics and has to do more work than the resource share allows. Then come the Seti outrage and it would refill the cache, wash, rinse, repeat.


. . I am getting 14 day deadlines at E@H, 7 days I think at WCG and 72 hours at Rosetta. But as a backup I ran/run E@H with 0% resource share and I get 1 task at time so I have one waiting to report and one running. This works pretty well for me.

Personally I was just pondering what I was going to do for this years WOW event. Whether in fact I would enter at all as it struck me last year as not very environmentally friendly.
Seems the decision has been taken out of my hands. I will crunch on my 4 main machines until there is nothing left to crunch, then I will be left with 5 750 Ti's, 2 1050's, 2 1060, and a 970 with nothing to do.
Whether I will crunch for another project remains to be seen, SETI was really the only one that ever interested me.


. . I thought you had a 1660ti as well? But I feel much like you. I have left three machines on E@H because it was my 'backup' project but I only do their tasks on the GPUs. To utilise the CPU I have tried Rosetta but had several issues there so I moved to WCG where I am not experiencing problems. But I do not feel the connection with either project (however worthwhile) that I have enjoyed with S@H.

I'll go to a project that has an open source code for Nvidia GPUS and an off-line test suite similar to Seti@home.


. . Hey there Petri, nice to see you here.

. . Let us know if/where you set up shop, I for one will probably join you :)

I've been wondering what effect this news will have on the rest of the scientific community?

Will they ...
... see lots of skilled users with powerful computers, ready to take on a new area of science?
... mis-understand and read it (wrongly) as the beginning of the end of the BOINC platform as a whole?


. .Many are running out of work repeatedly because they are unaccustomed to such large numbers of volunteers :)

. . Hi,

. . I think this tells a story of what we are up against. This user looks like they did 'the right thing', when deciding to quit S@H on 19th March they aborted all their work, somewhere between 240 and 300 tasks I am guessing, maybe more because there are still 240 showing. But they seem to have 17,500 (roughly) ghosted tasks. Since they are no longer reporting to the servers the auto-ghost resend mechanism will not work. A shame they had not checked their stats earlier than their decision to leave, it might have taken just one ghost recovery attempt, because most of their ghosts would have simply 'expired'.

If a task is already on your valid list, then it won't be resent when its remaining wingman's task expires. When it expires, The WU will get assimilated and purged.


. . Provided it was not one with multipled group resends that still has one or more other wingman/men to wait on.

Parkes would have been the preferred radio telescope for Sgr A*.

and any space based array would be the more optimal solution again.


. . The things about looking towards the centre of the Galaxy is that there is a lot more of the Galaxy to be seen than out here on the fringe. There is a helluva lot of real estate to monitor between here and the actual Galactic centre. I guess if YOU were on a mission at the edge of the Arctic ice cap wanting to communicate with other people you would aim your dish at the North pole rather than say, London?

. . Oh, and one other very critical fact. We HAVE Parkes and have had for many decades. So when are you going to build these off world radio telescopes?

There is still the Southern Hemisphere yet to be checked with existing radio telescopes. And the more data from the north, the more points of reference for that area.

I'm not sure that we can interrogate that much more in the universe by using sites in the southern hemisphere. We have a pretty good idea what surrounds us in all directions. I think any amount of data we can get from that would be minimal. We are at the point that basing more telescopes off world are far more interesting.


. . Ohhhh ssooooo wrong, the truly Southern observatories can add so much more observing time on our own Milky Way galaxy which is where the best hope of getting a signal lies. Observing other galaxies (the main gain from off-world telescopes) is a worthwhile goal for astro-physics, but not so much for finding ET.

Again...very speculative on the return of SETI. I'm not feeling good about that prospect coming up.


. . Sadly nor am I. It might have a slim chance if there are people with serious clout pushing for it and someone/s with serious cash willing to sponsor it. So far there have apparently been no other projects looking to take advantage of the hardware and volunteer resources S@H has developed over 2 decades. <sigh>

projects who employ short deadlines don't have to deal with the bloat on their servers that comes from users like that.
I'm really enjoying GPUGRID for these reasons. 5 day deadlines FTW


. . Rosetta = 72 hours (wouldn't people complain here), E@H = 14 days. Both manage to function but I wouldn't recommend trying Rosetta on a really low end or very old system, it needs at least 8GB ram, it might work with only 4GB but I'm not willing to try it.

They might decide to cancel Tasks in the next week or so if they get a Canonical Result, which might upset a few people who have cached thousands of WUs :) but it might upset some very slow crunchers too.
Are people like the "1337" guy, and a few others; here to get the science completed as quickly as possible, or are they just here for the BOINC credits ?


. . Juan's proposal was that machines which have NOT contacted the servers since the official end of splitting have their outstanding tasks annulled. Other machines, fast or slow, that are regularly returning results would not be affected. But it is merely hypothetical anyway.

. . As for second guessing the motivation for the massive bunkers being reported, the inference would be the latter option. But a third option occurs to me. Perhaps they anticipated, like most of us, that the clean up stage would last for months, and they wanted enough work to keep their machines occupied for that time. I can understand the desire to keep a machine busy to justify the power used to run it 24/7, this is why I am running E@H, but I chose a method which would not contribute to slowing the whole clean up process.

At the current rate of return on the SSP, most of the results should be back in about 17 days.


. . True of those that are actually being crunched, even by slow machines. But the unfortunately large number sitting in limbo assigned to defunct rigs will be there till the last deadline passes.

Maybe a wise thing to do is abort and resend with a small dateline all the WU from hosts who last contact was before april 1.
If a host has not contact with the servers in the last 15 days is highly probable is a powered down host.
Just a suggestion.

If the Project Staff were in the lab, and not working from home, then it might be worthwhile.
.CA is still on lockdown as far as I know https://covid19.ca.gov/ so they may want to wait until they are back.


. . The way things are the deadlines will come first :)
