You need to decompress this file into SETI project directory (when BOINC switched off of course) if you don't want process VLAR on CUDA.
That is, if VLAR task goes to CPU app - it will be processed. If it goes to CUDA app - task will be aborted with error (BAD_HEADER).
EDIT: There was wrong file name (.exe twice). Archive replaced, please, remove secondary .exe by renaming manually or download new archive.

Leopoldo,
if I get this correct, VLAR-killing should produce a different error (bad-header and not missing output file), so I'll hope Raistmer is right, and the problem is corrupted downloads.
Greatings to all Earthlings,
Andreas

Whenever there is an error (of any sort), no output file will be produced, and so BOINC will report that it is missing. If there were download iproblems, BOINC would be talking about missing input files.

VLAR-killed result is indicated as missing output file in BOINC Manager (the idea was to not pollute science database with incorrect results, so result file is deleted by mod).
Truth about result was VLAR-killed or not You can see in your result at SETI@Home Tasks page ("Your results" button in BOINC Manager) - there is leftmost link at line with every WU, which leads to page with result. Raistmer's VLAR-killing mod add info about killng.

You were completly right:
"stderr out
<core_client_version>6.4.5</core_client_version>
<![CDATA[
<message>
- exit code -6 (0xfffffffa)
</message>
<stderr_txt>
VLAR WU (AR: 0.008423 )detected... autokill initialised
SETI@home error -6 Bad workunit header
File: ..\seti_header.cpp
Line: 212
</stderr_txt>
]]>"
Thanks again,
Andreas

Hi all,
the following questions may sound stupid to some, but I couldn't find answers to them with google:
How can I recognice a VLAR WU in my BOINC manager? I want to assign them to cpu manually while gpu is bu{y.
And what does the "name" of a WU tell me?
Greetings,
Andreas
