"Processor features" are truncated in Ubuntu 16.04.3
« on: January 21, 2018, 03:32:45 pm »
I am trying to use BOINC 7.8.3 to run a AVX project (LHC/SixTrack) on an Ubuntu 16.04.3 machine running on an i7-4770.  I am fairly sure that AVX works properly on this machine, but BoincTasks (running on a Win7 64-bit machine over the LAN) does not list it on startup.

Code: [Select]

Can you look into this?

You made room for the whole text?
It might be a BOINC client problem if it uses a fixed string length.
I put it on my list, but it will take a couple of months before I'm able to look at this more closely.

Yes, that is everything I see.  It is only truncated for BOINC running on the Ubuntu machines (I have five of them) viewed over the LAN.  BoincTasks shows all the extensions correctly for BOINC running on the same Windows 7 machine.

Thanks for looking into it.

That points to a problem with the Linux Boinc client, that's often much older than the Windows version.

I am running BOINC 7.8.3 on both my Windows and Ubuntu machines (except 7.6.31 and 7.8.4 on one Ubuntu machine each).  But 7.8.3 is in the Ubuntu (i.e., Debian) repository now.

You say the problem is only with the Linux machines, so my guess is still that this is a BOINC client issue.
