64GB of memory on Windows XP Home?
He must mean drive space then.

Ivan, if you are getting any error messages from BOINC (in the Messages window in BOINC Manager), could you please post them here then? Else please explain what you mean and if possible do that either in English or in German.

Or in your native language, if necessary, I'll translate it here. (I've notified him per PM too. This seems to be his first forum message BOINC-wide.)

"Ivan, ak dostavas nejake chybove spravy (BOINC Manager), mohol by si ich sem skopirovat? Alebo skus vysvetlit, co si tym myslel, podla moznosti po anglicky alebo nemecky.

Mozes napisat aj vo vlastnom jazyku, postaram sa o preklad."

"I've approx. 64GB free. Boinc man. is working on just one project,it is possible to participate on multiple projects simultaneously, with this I've meant to utilize these 64 Gb

(as I'm still a bit confused, I'm continuing per PM in Slovak language)

BOINC can run multiple tasks at once when there are multiple CPUs or cores in the system. You only have one CPU, so you can only run one task at a time.

You can still attach to multiple projects, get work from them. Then BOINC will switch between the tasks of each project for the amount of time you set in your preferences. Default switch time is 60 minutes.

Now, at this moment you are returning quite a lot of errors.

Nespr�vn� funkce. (0x1) - exit code 1 (0x1)

Mark, does that sound as a familiar error that your application will throw?
Sounds like the application here isn't compatible with BOINC 6.2.18

Hard to believe 6.2.x would be the reason, I'm using 6.2.x and 6.3.x nearly half year long. But... well, looking at my logs, I've never (at least since 19.3.2008) got an error, until I've installed BOINC 6.2.1 on 14.5.2008, I've got some 18 errors (to 48 successful tasks) since (and failed to report them, my fault)-:

trajtou-pt111 5.37: 5 x OK, on 5.10.45, 1 x error 1, 0:02 sec, on 6.2.1,

BTW, Mark, is it worth to repeatedly report such errors?

Message 2272 - Posted 23 Sep 2008 21:29:18 UTC

I got a reply from Mark on this "problem". He thinks it is a strange trajectory taken by the trajtou calculation. It's a known problem and it happens with about 3% of the tasks. Probably caused by sloppy coding by the original scientist who wrote the f77 code.

I'm just finding it weird that it happens more on 6.2.18 than on older versions, hence why I flagged it. Especially if you look at Chrastek's tasks that crash with the error, then look at others who crunched it without a problem through 5.10 and older 6.2 versions.

Peter, you do know that the "unrecognized" and "skipping" lines in the stderr.txt are benign and not actually of influence on running the task? They just say that the application wasn't compiled against a BOINC 6.2 API.

True. And similar with my task.

I did not know the exact reason, but I've thought of it being unimportant. Therefore I've disarded them from my reply, but... the lovely akismet disarded my reply.

I've forgot to repeat it the same in my second reply version.

Message 2284 - Posted 30 Sep 2008 7:20:37 UTC

The Pt111 code runs trajectories based on the random seed derived from the WU name. The combination of the initial random seed and the spefici hardware you run the WU on, the trajectory sometimes goed haywire. Tests on my machine here with many many seeds shows that about 3% of the trajectories do this. Reproducing such a trajectory of a client with having the exact same hardware is nearly impossible making it realy hard to fix this. When I have some extra spare time on my hand, I'll investigate this a bit more and seem if I can fix this...

This is what causes the original file IO error:

"Nesprávná funkce. (0x1) - exit code 1 (0x1)
endfile: truncation failed in endfile
apparent state: unit 1 (unnamed)
last format: list io
lately writing direct formatted external IO"

However, the XML parsing messages are new to me and unrelated to our apps I think...

They are caused by your applications. It's just BOINC telling you that you neglected to compile the applications against the newer BOINC 6 API. It won't hurt the running of the tasks, though.

Message 2292 - Posted 2 Oct 2008 7:44:27 UTC

Yes well, that is true we still use BOINC 5.10 cause it is very hard to run a project with multiple applications for multiple systems and keep up with every change of BOINC (both the API and the server side).

The real PITA is often an 'update' on a running project means bug-hunting for three full days before the project is up and runnning again... I understand BOINC continues to develop and change, but using it in production is a different story alltogether. Especially if the project is a one-man-show who also has other stuff to do ;-). You just don't want to mess up 10000+ hosts and have a downtime for more than an hour or so... For production stability is a must!
