Looking over my task list almost ALL (18 of 19 so far) of the UV reionization tasks HAVE FAILED that I have received and by MULTIPLE wing-persons.

Looking at your computers shows that only one computer of three have those errors. I strongly suspect that is something wrong with your configuration (but, I haven't any machine with win8.1 for tests).

THAT PC HAS NO PROBLEMS WITH ANY OTHER Universe task or ANY OTHER PROJECTS TASKS - ONLY the UV reionization tasks.

PROBLEMS IS NOT WIN 8.1 If you re-read what I said the tasks are FAILING FOR EVERYONE CRUNCHING THEM!

While I can't see the problems that Dr Who Fan is seeing (and I am using Linux at the moment as my Windows machine is doing other stuff), I do have one task that is invalid that all others have also failed on WU 6749023 for some reason it can't be validated.

No problems with other tasks except for the 'error' counter which are not errors but server cancellations and nothing to do with me.
State: All (466) · In progress (10) · Validation pending (13) · Validation inconclusive (0) · Valid (405) · Invalid (1) · Error (37)

Sorry Dr Who Fan but I have no access to the link you provided to see if it is the same problem that my Invalid work unit has suffered.

Also seeing a high failure rate with associated UV application errors on my Windows Based AMD system. BOINC Event Log mentions "missing results"

Reset my Universe@Home and turned off that Application in Preferences for now.

Not really...
Fail rate for this application in fact is quite high on Windows machines (about 14-15%) but errors happens nearly always at start crunching, so it not takes CPU power at all.
On Linux machines errors rate on 0.5% level.

This is exactly same source code on both (in fact in all) operating systems and architectures.

Let's put aside the differing rates of failure for now. Do we know the cause of the failures? Is anything being done to fix the problem?

Nothing on my side. That error not exists on any computer where I have access.
Of course, I can compile app with full debug options but this will produce tens of gigabytes info stored on server and seriously slow it and I'm afraid didn't send anything usefully as only on some configurations this error exists.

Edit:
It looks like the problem exists on some low end CPU's but I'm not quite sure about this.

The code (0xc000001d) as in (unknown error)- exit code - 1073741795 - (0xc000001d)
indicates an illegal instruction has been attempted (as per information from the internet).

So it needs to be found what instruction the work unit is trying to do that is failing, as BHSpin v2 work units run fine on this same computer.

And this same source code, difference is in input parameters, so it is not easy to find.

Edit:
Fail rate for Windows drops to 10%...

I had updated Windows applications yesterday to version with debug flags enabled.
Please let me know if this helps (on host where I get access it is helped).
New version is 0.03.

It's difficult to help you, if we can't download wus.... :-(

I got just one Universe Ultraviolet reionization v0.02 today.
It had a very low estimated time on it. I was curious so I ran it by itself. It failed immediately.

universe_uv_160803_4_4_2000_1-999999_22300_3
stderr reads: (unknown error) - exit code -1073741795 (0xc000001d)

it failed all three times and has been sent out again to a forth user.

I'll keep trying to test them when sent.
