"Processor features" are truncated in Ubuntu 16.04.3

[Jim1348]

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.

Can you look into this?

[fred]

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.

[Jim1348]

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.

Here is the discussion on the BOINC forum where the experts there thought it was a problem with BoincTasks. 
http://boinc.berkeley.edu/dev/forum_thread.php?id=12255

I have confirmed that the relevant BOINC files include the missing flags, and apparently they get transmitted to the BOINC project servers.  It is just a question of where they get dropped going to the Messages tab.  I can't say beyond that.

[fred]

I put it on my todo list, but that may take a while.

[Jim1348]

No problem at all.  I now know where to look for the values, it just threw me for a loop when I first ran into it.  You will save some people problems though by fixing it.  Thanks.

In 1.77:
Changed: Messages: If the text is > 180 character, the remaining text is moved to the second line.✓

[Jim1348]

I installed 1.77 and rebooted both the Windows 7 64-bit machine on which it is installed, and Ubuntu 16.04 and 18.04 machines that are connected over the LAN.  But I still don't see avx and avx2.

Are there any checks I should do?

EDIT: I have no problem with a Windows 7 64-bit machine that I connect over the LAN.  It is an i7-3770, and avx shows properly there.

Yep something is still not right.
Check the Computer tab and click with the right mouse button on a computer and select computer properties.
Next with the right mouse key, copy all to clipboard.

Are these all right?

[Jim1348]

This is for the i7-8700 (Ubuntu 18.04).  The avx and avx2 are OK there..

OK Thanks, I will take a look.

[fred]

I checked.
Not much I can do, the data is from the BOINC client and it is as it's send back to BoincTasks.
The message buffer is truncated at 256 bytes at the client side, not much I can do about that.
