Oh now it looks like georgem is crashing too with the same NFS errors. Ha ha. Happy Friday afternoon...

- Matt

Ouch, everything bad happens on Friday near quitting time. :(

In my extensive experience as an experimental physicist at various institutes around the world, everything bad happens on a Friday afternoon after the technicians have left, but before the scientists start knocking off for the weekend.

One Note, If when compiling the app, If it fails with an error, check the client sub-directory anyway for the compiled app, there are two Bugs with compiling seti_boinc from head,

If you use a more minimal configure, it fails with the following, but the app is still compiled:

In file included from <command-line>:0:0:

Claggy

You're right, the executable was there. Running now, tho' BOINC doesn't seem to be reliably able to determine the number of CPU cores -- sometimes it thinks 1, sometimes 2, finally settled on 4. I've never worked out how to use the fifth core in Ubuntu, but since it's less powerful and the "real" CPUs look like they'll take about 100,000 seconds per WU I doubt that it would bring me much anyhow.

Thanks for your answer!
In the meantime I installed the most Boinc packages, include boinc-dev. I think this is what you mean. Nothing happend, still "boinc not found".

You need to tell the ./configure where your BOINC headers are located. E.g.
[tegra-ubuntu:seti_boinc] > head -50 config.log This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake. It was created by setiathome_v7 configure 7.28, which was generated by GNU Autoconf 2.69.

24) Message boards : Number crunching : thinking about upgrading GPU's (Message 1651807)
Posted 11 Mar 2015 by Profile ivan
Okay i have been running GTX 570 in SLI for a few years now. I was thinking about moving up to the GTx 980 but one at time (might do SLI again later in the year).

so the Q: is the 980 that much better than the old 570's i have now.

SP GFlOpS Power (W) GFlOpS/W GTX 570 1405.4 219 6.41 GTX 980 4612 165 28.0

Multibeam support (at least) for that could be relatively quick, since it should I guess run Cuda natively (taking the specs at face value). Should manage OpenCL too, though I haven't read the Tegra SDK details on that. For My Nexus 9, I'm having to look at the viability of a Renderscript port as well, because Google decided to go with their own language instead of using Cuda and/or OpenCL.

Guess it's time to ask (again) if anyone's managed to get MB CPU tasks running on a Tegra TK1 Jetson. I got the CUDA version running relatively easily, and my digital hologram reconstruction, but when I tried the CPU version -- it runs fine manually, but crashes when run as a BOINC task. I should really look at it again but at the moment I'm up in my all in assigators trying to bridge the gap between xxxx IT and yyy scientists to get yyy@Home running for volunteer computing. (Of course, most of you know what xxxx and yyy are, but I'd better be circumspect.) With a little bit of luck, we'll have things ready for the public in late autumn; with a lot of luck, earlier!

I'm sure it will all be fine, in time for the next outage :-)
No tasks left to do now though. Fans are going at very low speed.

My temperatures at work have dropped from 75-80 C to 30 C. Apparently the CPU fan liked being warm, it's now making so much noise that I called the IT guy over and asked for a replacement!

It's working just fine.

No, it's not.
If it were we would have had a full Ready-to-send buffer by the end of the day of the weekly outage.

Grant, for the sake of your blood pressure -- don't look at the cricket graphs just now! :-/

They've just finished a lot of NBN work in Darwin and I'm wondering if they've pinched some of the bandwidth allocation from Alice Springs to boost the speeds up there.

Network speeds still suck up here.

I was shocked at the speeds my brother was getting in Byron Bay until I looked at his modem and found it was quoting over 10 Mbps achievable, but an actual rate of 1.5 Mbps. Seems that that is the plan he could afford years ago and he hasn't updated since. (And his ISP apparently hasn't told him that faster plans are now available.) Also his monthly limit of 3 GB peak and 5 GB off-peak would drive me doolally -- and I'm only getting 6 Mbps here (but unlimited data), I should change to fibre because it's strung to the telephone cabinet embedded in my front hedge!

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:

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 have none left in my cache.


6 of them sitting in my invalids.

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