1) Message boards : News : New Poll Regarding GPU Application of N-Body (Message 71003)
Posted 22 Jul 2021 by Profileadrianxw
Post:
If the GPU version is doing the same work as the CPU version in roughly the same time, then, no, don't distribute it. GPU versions have a habit of also needing some CPU, so the net result is some CPU plus a whole GPU for the same effect as a CPU. Waste of resources.

Post:
I've just aborted a work unit. 6+ hours CPU, only 8% complete, deadline later today. Your work units normally execute in a few minutes on here, (4GHz i7 + GPU). All other units aborted also before they start, NNT set. Something is wrong now.

Post:
In forums like this, it is typical to quote part of, or all perhaps, of the comment your post applies too. The reason is very simple, there can, and often will, be other posts between your post, and the post to which you refer, in other words, it is helpful. With regard to me leaving, I had, in fact, left, I'd got sufficiently irritated by the repeated database issue that I'd decided enough was enough, it was even possible that having one less person, may have saved just enough resources here to help with the problem, but within days of me doing so, the upgrade took place, so I restarted.

>>> All the questions here have answers in other threads.

What you say there is possibly true, but if, as I, you are connected to many projects, reading all threads on all forums at all projects would take more than a day per day.

The solution for me, is to reduce the number of projects I support, the ones I drop first are the ones that "irritate".

I have received credit for completed jobs today. The credit is a little odd, I would have to say, but it is there, examples:

This one:

https://milkyway.cs.rpi.edu/milkyway/result.php?resultid=174955615

... gets 227.13

whilst this one:

https://milkyway.cs.rpi.edu/milkyway/result.php?resultid=174954011

... gets 133.62.

... despite the first taking a little less time to run.

A lot of jobs finish as inconclusive, but later are accepted and credited, this is likely a different issue.

Post:
I see that a new server is to be installed this week, I might leave the project on for a few days and see if this fixes the problems I have seen, If it does, then maybe I'm not gone!

Post:
Unable to upload is an almost daily occurance here, it is something you very rarely see at other projects. It is not a new problem, it has been lurching along like this for ages. When the already downloaded tasks are finished, I'm gone.

Post:
Todays database unavailable was just about the last straw for me. I tried to post a message about why I was dropping the project, but couldn't because the database was unavailable. The recent invalids is another observed issue. No new tasks set.

Post:
Yes, seems a little odd, perhaps all of them JUST managed to upload before the outage started. Bit of a coincidence, but coincidences do happen. All running normally again now.

Post:
I had a bunch of work units waiting to report, but could not do so, they did, however, upload. Is the up/download server on a different supply?

It does not work anymore, it did when I posted it.

Post:
I saw this wu...

http://milkyway.cs.rpi.edu/milkyway/workunit.php?wuid=1559573628

on my system. Normally, the jobs here run to completion in 5-6 minutes, but this one was 56% complete, not increasing, and had over a day of crunching time logged. I suspended and released it, the percentage done dropped and it started again running to completion quickly. You can see by the sent/returned dates that something weird happened. I've not noticed this before here, but it has certainly worried me, as I have the project on here, a system I do not look at much, it is simply a number cruncher.
13) Message boards : News : Server Update (Message 66826)
Posted 1 Dec 2017 by Profileadrianxw
Post:
This morning, I had several complete jobs waiting, so I did a "Report", an hour later, they were still there so I did a "Report" again. After five-six tries over an hour, they did "Report" and cleared.

Something completely trivial and almost certainly unrelated, but you did ask.

I've also had a couple of unable to validates recently, a new aspect.

Post:
I am still receiving dodgy work units, this one...

http://milkyway.cs.rpi.edu/milkyway/result.php?resultid=2132050089

... arrived this morning, and did the 2 second fail effort.
15) Message boards : Number crunching : Errors (Message 66621)
Posted 16 Sep 2017 by Profileadrianxw
Post:
Looks like another bad batch of work units. All that have arrived today have quickly failed. No new tasks set for now.
16) Message boards : Number crunching : Percentage complete. (Message 66074)
Posted 3 Jan 2017 by Profileadrianxw
Post:
The current program SEEMS to be running okay, but I can see the percentage complete jumping up and down all over the place. Runs up to 20% drops to 5%, up to perhaps 35%, down again, sometimes many repetitions.
17) Message boards : Number crunching : Aborted by user. (Message 65105)
Posted 5 Sep 2016 by Profileadrianxw
Post:
I looked at my results page and was suprised to find over 700 work units flagged as "Aborted by user". As far as I know, I have not aborted any, let alone 700+.
18) Message boards : Number crunching : Fix For Truncated stderr.txt Files BOINC 7.6.6 (Message 63884)
Posted 18 Aug 2015 by Profileadrianxw
Post:
I have tried to download the newer BOINC version 3 times, each time, it failed with a generic failure message. I guess it will sort itself out after a while, I had not seen the problem anyway, so not a critical issue.
19) Message boards : Number crunching : Odd errors. (Message 63455)
Posted 23 Apr 2015 by Profileadrianxw
Post:
Three more errors today, (in the last 12 hours), no new tasks set. I think the failures are happening when the system is restarted, an inconvenient, but necessary action for me right now.

Post:
14 errors now. Some quick, others after considerable run time. Have not set no new tasks but will if this continues.
