Here I see some tasks based on SSE, others on AVX. Why this is so ?
My processors are all new ("Haswell" or newer), support SSE4.x, AVX2, and FMA.

When you first join the server will send you a mix of tasks using different optimisations and work out which is the quickest for each machine. It will then send you that type of task exclusively.
I understand that it will recheck occasionally but I’ve never noticed it doing so on my machines.

You can see your current performanche here http://gene.disi.unitn.it/test/show_host_detail.php?hostid=62240
click near by "Application details" it will show this page http://gene.disi.unitn.it/test/host_app_versions.php?hostid=62240
as you can see, FMA is currently faster on your pc

I suggest to download ALL 3 binaries, and a mini-benchmark (mini workload for a few minutes of your actual application). Then use whatever binary that delivers the best results.

Don't worry. after somme wu completed and validated, the server select automatically the best version

Yes, and avx on my other machine with a near identical spec :-

This is the way I restrict all WUs to FMA:
http://gene.disi.unitn.it/test/forum_thread.php?id=304&postid=2209#2209
You need to save a copy of the FMA executable that you can copy to all your computers:
/var/lib/boinc-client/projects/gene.disi.unitn.it_test/gene_pcim_v1.10_linux64__fma
Beware that when you install this and then click "Read config files" BOINC will wipe out all your WUs in the TN-Grid project folder so you might as well Abort them first.
Also, if you're new to BOINC you may benefit from a couple of tweaks to your cc_config.xml file.
I also recommend using BoincTasks to manage so many computers.

Why restrict it? Easier to let the system choose the fastest and you’ll get more work done.

Right you are, just my idiosyncrasy.

Fair enough, we all have our own ways :-)
