I've learned over the years to "NEVER" let Microsoft upgrade your video drivers. Most other drivers update fine but I've always had problems with their graphics drivers. Check and see if there are in your recent Microsoft update history.

Just slipped past Questor to become the top cruncher in the UK. :-)

That was nice -- I had a PM from Questor congratulating me on overtaking him. Thanks!

Never seen these messages before, interesting ...
2015-02-17 6:18:59 PM | SETI@home | Fetching scheduler list
2015-02-17 6:19:00 PM | SETI@home | Master file download succeeded
AFAIK, if BOINC want contact to the server, and get 5 or 6 times no well answer back, then master file will be downloaded. (for to download the 'new' server URLs).
Just to be clear "master file" is master_setiathome.berkeley.edu.xml:
<scheduler>http://setiboinc.ssl.berkeley.edu/sah_cgi/cgi</scheduler> <link rel="boinc_scheduler" href="http://setiboinc.ssl.berkeley.edu/sah_cgi/cgi">

Ah, thanks. I thought it might have been something like that, but I hadn't got around to go looking for it.

About time they got around to releasing the v3 for the E7's. All we had to drool over before were the E5's with their 18, 16, & 14 cores on 2 sockets. Now we can have 18c/36t with 8 sockets @ 2.5GHz

I must contact Boston/Viglen -- the in-socket Xeon Phi should be imminent. I couldn't see how to make the co-processor version do S@H but once it has access to all system memory...

You still don't see it do you? Here Look VERY closely;
#include "timecvt.h"
#include "db/db_table.h"
#include "db/schema_master.h"
#undef USE_MYSQL

I'll give you a Hint, the db/ part shouldn't be at the beginning.
When yo enclose it, it is seen as a different file.
"db/db_table.h"
Is Not;
"db_table.h"

That depends entirely on what you have your include paths (-I flags in gcc) set to. If an include path is "<blah>/include/db" (for example) then you don't need the "db/" but if it's "<blah>/include" then you do need it.

Both my systems now have some GPU work.
Most requests for work result in "Project has no tasks available" messages. Given the length of the outage & the lack of any AP work I think that will be the case for a fair while yet as the feeder struggles to meet the demand.

My colleagues at Imperial (ic-hep) are ramping down a bit now (500K RAC, they were at 1 M last month) so they may not catch up for a long while. Their story was that since we weren't running many LHC jobs at present (we're just coming to the end of a very long shutdown) they had to run SETI@Home "to keep the machine room warm"!
I'm currently working towards bringing CMS@Home online but it's several months away from going public.

Phew! Made it to 150M at last. The last bit has been a bit of a slog, with the recent problems, failures in my machines, and trying to (mis)manage it all for a month from the other side of the world, but I made it in the end!
Oh, and I see my team has made it to 200M.

Just check your folder for those tasks.

I've got 14 in invalids and another four in inconclusive.
This one has been out to eight hosts already.

I badly needed some WUs here. Its -20C outside.

It's +30 C outside here [28.641° S, 153.608° E] -- at 2330 local! Meanwhile, back home in London it's -5 C. Supposed to be warmer (~7 C) when I get back Friday night. Hope the warmth from my three home servers has kept Jack Frost at bay -- at the moment they are all still running and reporting results.

14) Message boards : Number crunching : No GPU Units Under Linux (Message 1619749)

The only GPU app currently for Linux is Astropulse,..."


Is there a technical reason that prevents the development or porting of a GPU app for MB WUs under Linux, or is it a case of no one taking or having the time to do it?

Various of us have our own ports, but it's hard to make a "standard" version due to the large variability between different versions, distributions and libraries. Also, you really need to have a compatible version of BOINC and even that is hard to compile, especially if you want the graphical boincmgr (the standard distribution doesn't work on most of my Linux systems, due to its requiring specific libraries).

Fun fact: the default Intel CPU fan for socket 1156 CPUs has no rubber plug underneath the sticker.

Probably the case for a lot of smaller computer fans these days.
The fans on my GTX 560Ti were the same- it was a case of carefully (and quite forcefully) levering the fan blade assembly out of the motor assembly.

16) Message boards : Number crunching : Problem with BOINC right click (Message 1618711)
Posted 25 Dec 2014 by Profile ivan
Whenever I right click the BOINC taskbar icon it opens the notices tab instead of the menu so I can snooze BOINC. It happened after I upgraded from 6.10.60 to 7.2.42, did try running the installer to repair and it worked, but next time it opened the notice tab again. Installing 7.4.36 didn't help. Any ideas?

Have you tried double-(left-)clicking the icon?

I had to take the thing apart a moment ago anyway, as the AMD HD6850 in it ran 52C at idle, a tad too much. So after cleaning that out and cleaning the CPU heat sink, I took my spray can of WD40, put the straw in, wrapped the CPU fan up in a paper towel and sprayed the tiniest bit of WD40 in the opening between the fan head and the spindle. Turned the fan a couple of times, repeated the oiling, then put the system together again.

Immediately upon starting up the difference was noticeable. The whole system starts up ultra quiet now. So thanks to you, unknown person, for telling on these forums that you would oil your fan(s) regularly as well. You made me a believer. :)

Just remember that WD40 is not a lubricant, it is a Water Displacer (not surprisingly, the 40th formulation the US Navy tested...). Don't rely on it for long-term service, though it usually works as a short-term solution. [When you're in an aged Mini, coming back from London, Ont., to catch a flight from Toronto back to Switzerland, in a streaming sleet-storm, you tend to be very glad that the service-station you limped into on less than three cylinders has WD40 for sale, to spray on your spark-plug caps, leads, and the distributor.

It's easy

If it doesn't move and it should you need a hammer

If it does move and it shouldn't use duct tape

If non of the above then it's an electrical problem and you need an electrician

I'm also interested.

Faster graphics cards would of course be better. I know nothing about rack cases. Do they make them taller so you could put full height cards in them?

Yeah, there are a number of different configurations. One of my Supermicros is only 1U high but it has a C1060 and a GTX460 (sans fan!) in it -- they lie flat so height isn't really an issue. Similarly with my latest 2U chassis -- it has two slide-in dual-Xeon systems, each of which can take a full-size PCI-e card; we have the same chasses in our Grid cluster with four smaller slide-in dual-Xeons, but they can only take low-profile cards (like the GT640 with appropriate hardware). One of the other groups in our Department tested an Intel system a while ago that could take eight (IIRC) PCI-e cards, standing up, but I don't remember the chassis size or whether they were full-height or low-profile slots.
