According to https://en.wikipedia.org/wiki/X86-64 SSE2 are an arcitectural feature of the 64 bit compatible processors, meaning that all 64 bit processors does have it (if I'm reading it correctly).

So right now on the applications page, it says that "Microsoft Windows running on an AMD x86_64 or Intel EM64T CPU" with "no-tag" is using 494 GigaFLOPS and "Linux running on an AMD x86_64 or Intel EM64T CPU" with "no-tag" is using 40 GigaFLOPS.

These could be run much faster as SSE2 applications, hence a lot of wasted cycles, that could be avoided by removing the 64 bit version of the "no-tag" program and only let the SSE2, SSE3 and PNI versions remain on 64 bit. Then the 64 bit client would always choose a minimum of SSE2 and wouldn't have to waste cycles testing if the "no-tag" version is faster.

Do we need virtualbox for running LHC tasts? I know that some of the other programs need virtualbox in their current projekts (e.g. ATLAS).

I have gotten quite a few over the last days/weeks, looks like some work is being submitted atleast a couple of days per week. Just not so much at a time :)

By the way. This host is on the loose again making invalids (currently 6317 invalids):

Maybe you need to ban him for another 2 weeks :)

Jep. That was what I was thinking about. Same here, in it for the Science and not the credits. I just fear that if a task gets rejected it's lost work even though 2 computers came with the correct answer.

Trying out 3 rights sounds like a good plan to test. However, don't you still need to have a total of 5, like we used to have? Right now (if I understand it correctly) having a total of 3 means that if 1 fails, it will not send out new and noone will get credit? Or is it just me reading it wrong?

So it will be 3/5/3 (3 wrong, 5 total, 3 right). Then the least resource will be lost and it will still have a chance to validate even though 1 of the 3 are wrong.

Go to "your account", then press SIXTRACK-settings (translated from my danish version). There you should have a setting called: hould SIXTRACK show your computers on its web site? Choose "NO". Then it should not show your hosts.

The boinc client stopped downloading tasks because avast was blocking them, causing both my machines to run dry of work.
