1) Message boards : Number crunching : Sixtrack (notag/sse2/pni/sse3) (Message 27838) Posted 6 Nov 2016 by Uffe F Post: 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.
2) Message boards : News : LHC@home consolidation (Message 27835) Posted 3 Nov 2016 by Uffe F Post: 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).
3) Message boards : News : BOINC Server up (Message 27655) Posted 10 Dec 2015 by Uffe F Post: Thats strange. When I use the link it goes to the right forum page. Well, use the link below and go in via the message boards (Lower left side) and choose the right board http://lhcathomeclassic.cern.ch/sixtrack/index.php

5) Message boards : Number crunching : Available work? (Message 27615) Posted 19 Oct 2015 by Uffe F Post: 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 :)
6) Message boards : Number crunching : Host messing up tons of results (Message 27318) Posted 7 Apr 2015 by Uffe F Post: That sounds great. That will give a more steady throughput of full results you can use.
7) Message boards : Number crunching : Host messing up tons of results (Message 27297) Posted 7 Apr 2015 by Uffe F Post: Double post...
8) Message boards : Number crunching : Host messing up tons of results (Message 27296) Posted 7 Apr 2015 by Uffe F Post: By the way. This host is on the loose again making invalids (currently 6317 invalids): http://lhcathomeclassic.cern.ch/sixtrack/show_host_detail.php?hostid=9996388 Maybe you need to ban him for another 2 weeks :)
9) Message boards : Number crunching : Available work? (Message 27278) Posted 4 Apr 2015 by Uffe F Post: 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.
10) Message boards : Number crunching : Available work? (Message 27269) Posted 3 Apr 2015 by Uffe F Post: 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.
11) Message boards : Number crunching : Retrospect: June, July, August 2013 WU? (Message 27209) Posted 7 Mar 2015 by Uffe F Post: Jep, still got 36 tasks from 2013 :)
12) Message boards : Number crunching : Host messing up tons of results (Message 27183) Posted 26 Feb 2015 by Uffe F Post: This host has a lot of invalid (4876) and a lot of inconclusives (1748) and errors (269). Maybe it needs to be looked at. http://lhcathomeclassic.cern.ch/sixtrack/show_host_detail.php?hostid=9996388

14) Message boards : LHC@home Science : Hide host info (Message 27125) Posted 8 Feb 2015 by Uffe F Post: 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.
15) Message boards : Number crunching : Error reported by file upload server: Server is out of disk space !? (Message 27112) Posted 29 Jan 2015 by Uffe F Post: Errors started here again also. But it makes sense if there is no jobs being validated at the moment. Then it gets full. I have multiple jobs not validated yet that have 2 answers.
16) Message boards : Number crunching : Error reported by file upload server: Server is out of disk space !? (Message 27107) Posted 29 Jan 2015 by Uffe F Post: I got a lot of long ones that are resends, so that will atleast clear some up.

18) Message boards : Number crunching : Avast antivirus - false positive (Message 27075) Posted 21 Jan 2015 by Uffe F Post: making an exception in avast helped me also. Lost 19 WU's on it though, as I wasn't home all day. Atleast it wont be a problem the next time now :)
19) Message boards : Number crunching : Avast antivirus - false positive (Message 27072) Posted 21 Jan 2015 by Uffe F Post: Have the same problem. The boinc client stopped downloading tasks because avast was blocking them, causing both my machines to run dry of work.
20) Message boards : Number crunching : Where did all the work go? (Message 27057) Posted 14 Jan 2015 by Uffe F Post: Yeah it's great with work, and currently there is 190K ready to send and almost all I have are the long ones. So there is hope that we will have work for the next week already uploaded :)

Next 20
