1) Message boards : Number crunching : NoContraintsWithDisk200 vs. south4s (or whatever) (Message 68547)
Posted 2 days ago by ProfileSaenger
Post:
Just a thought here: I suspect most (if not all) of the people having the "instant fail" trouble with the new work units might be running older versions of BOINC which have a maximum command line capability of about 1024 characters. There have been other tasks in the past that had lots of parameters and overflowed that limit, though I'm not sure it produced this error.

In particular, it appears the OP is using 7.2.42 (which certainly truncated command lines for one of the earlier groups of tasks with extra parameters!)

So if nothing else seems to work it might be worth trying a newer BOINC client if one is available for your distribution. I think 7.8 didn't have this problem, and I know 7.14.2 doesn't because that's what I use and it runs these new tasks quite happily.

But the names of the fine running WUs are considerably longer than the ones of the failing WUs.
Perhaps I'll try a new BOINC some time later.

Some reason your BOINC.exe can't create the slot directory for the WU?

No, as it's doing fine on the NoContraintsWithDisk200, just the south4s are crashing. And I don't care about linguistic sophistry, they fail, full stop.
Before everything was fine as well, so nothing here with me.

I got tons of invalid tasks in the last couple of days, and I don't have a clue why. I know the names of those who get crunched fine lately all include NoContraintsWithDisk200, while those without this, and currently south4s in its name, all crash asap. As I don't loose much crunchhtime due to their immediate crashing, I won't stop with MilkyWay, but...

I'd like to know how I can avoid DLing those WUs that won't run, or, even better, how to get them to run on my machine.

I'm getting credit, even for WUs that got crunched after the maintenance. And I have a bunch of _1 WUs an my machine. So they are probably getting things sorted by and by.

Not invalid, just not yet validated, because they are waiting for the wing-WU.
On one and the other of your computers.

Yep, all of my WUs are _0 as well, so it looks like _1 are kept behind for now. What went wrong after the restart of the machines?

I aborted all with 18 or 20 in the name, and without a fixed somewhere. All others run fine. Some seem to be resend until 5 are done, but they don't last long.

Hey

Add me pls to the List, same Errors here, over 90%. Same Batch of WUs
"de_modfit_fast_18_3s_146_bundle5_ModfitConstraintsWithDisk_Bouncy"

LG Sandra

Wrong;)
I've got some 20 in my list of errors as well, and some are called Random, some not. Looks a wee bit random to me ;)

P.S.: I just saw, you changed your post, so now it fits here as well ;)

Something's fishy, but they only take a second, so not much is lost in terms of crunch time ;)

N-Body does not use the GPU at this time, as the GPU code is still in development.

Jake


Then why do you send them out, and block the GPU from doing real work?

Please look in this thread in numbers as well, these WUs should probably not be sent to GPUs, as they just obviously waste their power.

I just looked those nvidia-nbodys up in my WU-list, and saw that they get extremely poor credits for a GPU-WU. Here's an example with paallel CPU-results (290919767):

They all took about the same amount of time on the CPU and on the clock, but mine probably used the GPU as well, 'though I can't say, as it crunched while I was away from the machine.

There are two possibilities:

    -> They really don't use the GPU, then they should never be sent as GPU-WUs
    -> They use the GPU, but are so poorly programmed, that they can't make any real use of it, which should not happen as well
    -> They use the GPU for crunching, and really do work on the GPU, so they should be awarded much more credits compared with CPU-only.



If all results of one WU should do the same work, the GPU-ones are a waste of ressources.

Post:
Is the thread in the polish forum the only support thread? Because most people will very probably have problems to register there...

Anyway, in hope it can be answered here, I copy here a question from the SETI forums:

When i open it, I have to configure it to a new host, and I have no clue as to how to do that. I was wondering if anyone here knows what to do?

It is asking for Host Nickname, Address and password, using port #31416


That's what BOINC always asks if you want to attach a new host to a new project.
If you chose "Existing Account" instead of "New Account" you just have to give your email and password.
If you use BAM! (or any other account manager), you can attach projects to your android there as well.

I have just finished my first 2 WUs on my Galaxy S2, not that bad for a mobile methinks.
