Hope this will answer some of your messages.

We still have some 34,000 WUs NOT being taken. We have apparently
almost 6000 in progress.

We introduced SixTrack Version 4.5.03 on Wednesday 22nd
January after extensive testing on boinctest and at CERN.
Unluckily Yuri flooded us with work at the same time
and AFS blew up leading to a huge backlog of over 16,000
results to be downloaded.

1. Results Validation;seems to be OK. I summarise that,
countimg from 0-59 we do NOT CHECK Words 51, 59? and 60
in fort.10.

The validator log shows many many "cannot open" supposedly
existing results for comparison. They were probably lost
somehow.

2. Assimilation; the log shows
"Herror too many total results" !!!
There are about 2000 (1979) unique messages and cases/WUs.
I suspect we may nedd to clean the database and remove results
(with clients losing credit I am afraid, but they will probably never
get credit for these anyway).
I could delete them from upload but that would probably be worse.

3. Scheduler log: there are about 2.4 million messages of which
there are 1.64M unrecognised messages, multiple messages per WU.
This is perhaps significant!
previously these messages existed only for Macs as far as I can see.
here is one case:

I am not an expert but it seems to me it might explain work not being taken.......
(but never saw this with boinctest!).

Other issue; one client reports "Cannot Create Process" mon Windows 7.
May or may not be significant.

Are executables 'signed" OK?

So all a bit complicated but hope to sort it (very) soon.
Eric.

P.S. The "unrecognized" messages wre for only Mac systems in the past.

take a note on ratio valid:inconclusive:invalid:error
is has significantly shifted recently from
Validation inconclusive (614) · Invalid (63) · Error (197)
to
Validation inconclusive (1036) · Invalid (233) · Error (211)

and now this

In progress (42) · Validation pending (389) · Validation inconclusive (6842) · Valid (3265) · Invalid (1887) · Error (218)

Have fun. I am standing by. :)

3. Scheduler log: there are about 2.4 million messages of which
there are 1.64M unrecognised messages, multiple messages per WU.

That looks like the server is trying, but failing, to parse an <opencl_cpu_prop> block in the user's sched_request file.

OpenCL on CPUs is a very recent addition to BOINC (previously OpenCL was only supported on GPUs), and the user is requesting using BOINC v7.2.33, which is indeed the newest 'recommended' client version - deployed 26 Nov 2013.

If you haven't updated the server code since November, it might be wise to do so (though I haven't heard of the new section causing any problems at other projects). Else, you might need to consult David Anderson.

Thanks a lot Richard. This almost certainly explains
the not getting work issue. My colleagues built
the Windows execs using a very recent BIOINC version
I suppose and our server BOINC is older. Eric

---

We have restored old executables and seem to be back in business.
Need to clean up, clear up and the post mortem news will follow.
Eric.

Eric please note aloso this Thread: http://lhcathomeclassic.cern.ch/sixtrack/forum_thread.php?id=3799
there are problems with Winxp and the new Version.
In the Thread a Solution ist described.

regardes Franz

Thanks for that.....many thanks. Don't know how I/we missed it.
The inquest continues. Eric.
