Hi, all my Gaia_8 WU's error similar to this one below. I notice that sometimes my Linux wingman also fails the same . The same machine runs WU's for milkyway & spacious@home fine

It's running on a standard Debian 12 machine, GenuineIntel

I would guess the application requires some instructions that your CPU doesnt support, like SSE4 or AVX.

Did you install libquadmath0 ?

Did you install libquadmath0 ?

that is not necessary with this new application. that was only needed on previous gaia apps. the new app is doing completely different research.

also, when you didnt have it (with the OLD app), the error message specifically told you that was the problem.

Ok - i stand corrected.
Thnx for info.

Thanks, that could be it, it had similar problems with Gaia_4 too BTW

If so It would be good if the apps section indicated that was a requirement , as this machine does meet the Linux running on an AMD x86_64 or Intel EM64T CPU requirement, and is able to run all work units from asteroids, milkyway,spacious, Rosetta, WCG and einstein without issue

The machine needs a refresh so am putting Debian 13 on it tomorrow, I'll see if that helps

Updated to debian 13 and boinc 8.20, but still errors. I suspect the project needs to feature of the CPU, which while understandable, should really be made clear, or coded around
