Finally we have a working GBT splitter. SETI@home v8 will process Arecibo and GBT data.

The code changes are pretty small, but the results are not compatible with SETI@home v7, so only process v8 data will v8 clients.

First release will be linux x86_64 only to begin with. We're hoping to have windows and macos graphical releases in another week or so.

None of the workunits shown are available yet. Jeff if still working out some splitter bugs. It's unlikely that there will be real work before Tuesday, so you may want to wait on using anonymous platform until then.

It was more to actually get some v8 Wu's for offline testing, then Jason and Raistmer will have results to work with.

Will v7 e going away? Will v8 be able to crunch data from all sources? Or will v7 stick around, in parallel?

Those who want to participate v8 -beta test, remember to enable SETI@home v8 application at Your S@H Beta preferences -page.

My setting was NO when I did check it.

Eric, last addition breaks compilation under VS2010:

1>..\analyzeFuncs.cpp(781): error C2146: syntax error : missing ')' before identifier 'PACKAGE_VERSION'
1>..\analyzeFuncs.cpp(781): error C2059: syntax error : ')'

Line affected:

    retval=outfile.printf("<setiathome_version>"PACKAGE_VERSION"</setiathome_version>\n");

Also, VS2010 x86 build path non-functional though such release config exists.
No FFTW x86 DLL/lib provided. Only x64 one.

why there isn't an option "automatically include me in future projects available"?
it has been done on WCG, so it's possible!

crossposting from main:

I did a circular to all volunteer devs known to me, to coordinate the public optimised app update effort. (Commonly known as Lunatics). If you didn't receive it but think you should be on my list, please provide email address by pm and planned area of involvement. I should have the core team, but may have missed a few of the more elusive contributors or gotten an email address wrong.


P.S. Eric, you didn't say which Tuesday ;)

First one done, 4 minutes to overflow :/

For the second initial estimate is about 1 day 18 hours. If that holds it would be about 7 times longer than Arecibo workunits.

There are no GPU apps for v8 yet, so they're restricting it to CPU only in effect, Ignore the spurious scheduler messages for now until:

1) there are v8 GPU apps,
2) they're been tested offline, preferably across some different driver versions,
3) v8 GPU apps are actually deployed.

Slight glitch: the task has validated, but according to the WU page none of the replications have been sent yet! Main project status page says the replica is still 9,000 seconds behind the master, so I'm assuming it will come clean sometime after I've gone to bed.

Got my first Seti v8 7.99 task, from the slot directory:

setiathome_v7 7.99 Revision: 3112 g++ (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4)
libboinc: BOINC 7.7.0

and it is using the ancient fftw-3.1.1a fftwf_wisdom, I'll compare my 7.99 app (offline) with fftw-3.4.4 fftwf_wisdom with the Stock 7.99 app over the next few days.

After getting my first v8 work units i've recognized that the setigraphics executable is not working.
After some closer look : It is not a binary executable, but looks like a local build-script. ouch.

Those values are from the last time configure was run. The linked FFTW is what's current on el6. Still ancient, but it's at least 3.2.1 .

I take that back. Apparently 3.1.1a still lived in /usr/local and got linked in. Will be fixed in next release.
