1) Message boards : Number crunching : Waiting for shared memory, Linux 64-bit, (Message 1463878)
Posted 93 days ago by Profile Questor
I don't know how it shows in Linux as I only run Windows at present but if you set the BOINC preference for memory usage too low you will get tasks waiting for memory to become free. Might you have accidentally changed that setting(or perhaps all your memory is not being recognised)?

You have a couple of missing lines in your file.

The structure is :-

<cc_config>
<log_flags>
[ ... ]
</log_flags>
<options>
[ ... ]
</options>
</cc_config>

So you should have :-

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

3) Message boards : Number crunching : Asking for efficiency advice (Message 1144764)
Posted 965 days ago by Profile Questor
I realize that there is a creditnew effect working its way through RAC figures these days, but my rigs are off about 40% from where they were about six months ago. While I have reduced WU per gpu down to one on several cards/machines,(because of heat) I can't imagine that it would make that much difference. I've even upgraded two machines recently. All machines have been running fairly steady (when WU availability allows) for several months. I run a stable 266.58, a stable Lunatics x0.37, and a stable BOINC 6.12.33, 24/7 on all machines. I was having a lot of invalids and errors months ago with newer drivers. I since rolled back, and that seems to have calmed down. As I look at my results, they seem to be OK time wise. I'm just concerned that I don't get near the RAC that I used to with better hardware. What am I missing? Where can I look to find any bottlenecks? Thanks for any advice.

Russ


280.26 has made a big difference to one of my machines and seems stable. The GTX570s were downclocking so that I was seeing GPU usage in the 80% range instead of 99% now - only seen on Vista64. XP 32 and 64 machines always show 99% with both drivers. (all cases with lunatics 38g)

That was starting to make a difference to RAC but at the moment it seems to be generally on the rise on all my machines for some other resaon.

Hi Sutaru

I have the tray icon and am using XP with 266.58 drivers.

If you do not have it, run the Nvidia Control Panel and go to the Desktop menu. Under there is an option to tick for 'Show notification tray icon'.

Hope that gives you what you are looking for.

6) Message boards : Number crunching : computer crashes when usb device plugged in (Message 1047024)
Posted 1255 days ago by Profile Questor
When you insert the USB device and the machine does not reboot - does the USB device actually work?

What I'm wondering is ususally the front panel sockets go to a header which plugs into the motherboard. If the header plug is misaligned on the motherboard connector it may be shorting something out / causing a reset when you insert your device.

The header sockets arent usually keyed in any way and it is possible to insert incorrectly when they are in an awkward position - I've done it myself.

Another thought - check for any small conducting foreign objects that might have found their way into the USB socket which may cause intermittent shorts when a device is inserted.

7) Message boards : Number crunching : Corrupt database? (Message 1044021)
Posted 1270 days ago by Profile Questor
My computer with ID 5455034 shouldn’t be at Rank 21, as I have RAC 47,504.20 .
It should be at Rank 16.
I think something is going on with the database.


I have noticed this before. I think those pages are based on some sort of static data which gets refreshed periodically (you can only view the first 10000 hosts). If the process doesnt get as far as updating everything some pages show old data. Page 1 had values less than yours a while back but it has now changed and you actually appear in pos 20 and 21 at the moment!.

Posted 1283 days ago by Profile Questor
Apparently it doesnt work on XP. http://support.microsoft.com/kb/262265

The work around is to change the IP address to a non working one for your router and then back to dhcp (or a working static address).

Disable
=======

netsh interface ip set address <interface name> static <ip address> <mask> <default gateway> <gateway interface metric>

e.g.
netsh interface ip set address "Local Area Connection" static 1.1.1.1 255.0.0.0 1.0.0.1 1

Enable
======

netsh interface ip set address "Local Area Connection" dhcp

Tried on XP and works OK.

Posted 1290 days ago by Profile Questor
Hmm..............

Last contacted SETI on 10 Sep 2010 22:17:04 UTC.

I would perform a project reset. More important to get the machine back online with SETI since the completed work is probably lost anyway.

Be advised that you will probably lose the optimized apps installation also so be prepared to reinstall the optimized apps again.

This is what I would do but it's your machine...............


That machine is a ghost machine created when a machine accidentally booted from the wrong disk which had an earlier copy of a SETI install on it. I can't merge the two machines. ID: 4650366 and ID: 5488329.

The machine which wouldnt report finally has with 211 tasks (ID: 5516356 ).

Is anyone else having problem reporting?

Most of my machines are reporting one or two tasks at a time OK.

However I have one which hasnt reported for a time and now has over 100 tasks to report.

When it reports I get

Hi Tim,

No, it's the same size as the normal client_state file. The other one there is client_state_old, but it is exactly that - 6 months old.

Looks like I'm gonna have to get a new machine id, and try to get some more work.

The machine hasn't changed, so I should be able to merge it with the old one, but I will lose about 800 tasks.

Damn! This was just starting to rip through a good few wu's too. Now it's sitting on 800 tasks it can't work on, and I can't seem to get any new ones either.

regards, Giz.


So annoying when that happens. Assuming your 6 month old file has the same host cpid value as you were currently using you could use this to start Boinc and detach/reattach which will release those orphaned 800 tasks.

13) Message boards : Number crunching : BOINC not downloading GPU WUs (Message 1033501)
Posted 1307 days ago by Profile Questor
There was a server side change made a while ago which means that VLAR tasks that dont run as well on a GPU are only allocated to CPU. You may be experiencing that. Otherwise the MB tasks run on CPU or GPU.

Do your CPU tasks have a name something like xxxxxxxxxxx.vlar_y - those a VLARs which wont get assigned to your GPU.

With a lot of users currently requesting new work you may just have been unlucky and got 0 allocated on that request.

If you have surplus of CPU tasks you could look at Freds Reschedule app which allows you to move tasks from CPU<_> GPU.

Note: The other scheduler app on Lunatics does not work well with Fermi cards.

Posted 1312 days ago by Profile Questor
Hi all, one of my hosts seems to be getting a lot of errors in the last few hours since the servers came back online Host ID: 879910 I have another three WU's that are yet to report and I noticed the run time is identical when they exit at 01:51:44 I am running AK's optimised app and they are non Cuda WU's, anyone having similar problems?
One of them link below

EXIT STATUS -177 (0xffffffffffffff4f)

http://setiathome.berkeley.edu/result.php?resultid=1698440392


There are a few threads with explanations as to the cause of these errors but as a quick fix you can download the new Reschedule tool by Fred which has an option to fix the problem. (The -177 happens when a task exits because it has reached a maximum timeout value)

New Reschedule tool

Getting this on all machines, and the cricket graphs are dying.

T.A.


Getting it on all my machines as well. At first fails to upload because of space but then succeeds.

It is hard to believe the SETI folks wouldnt have spotted the disks were full (unless nothing could be done about it) - I wonder if it is a deliberate mechanism to control the upload storm by limiting the amount of disk space available? However, I did wonder if the increasing pendings and ghosts were eventually going to cause a problem.

that would involve w*rk on my part!!!

Sorry, says I dont have enough credits to write in the forum.

Does the IP address of your computer affect Boinc from connecting? I travel for work, so the ip address is never the same, and online it says my ip is the same as when I am at home, not the new one on the road. My laptop continually says Retrieving Current Status. My Server continually says Processing Suspended: User Active.

The website wont even update the computer info on any of my computers running Boinc.

Thanks for a reply (if you want to).
Peranha


Sounds like two problems on 2 machines? The server has "Do work when computer is in use" set to No (unticked) and on the laptop boincmgr cannot connect to boinc.exe perhaps because of firewall blocking app connection via port 31416?
I have two routers at home (work and home) which give PCs different IP addresses and I connect via both at different times without problems.

Welcome back, Mark!

I'm trying to get the full total from reading the thread. It's easier than figuring it out from the database since there's no way to separate these donations from others (Other than the $1000 donations). I think that it's $9000 including the donations of less than $1000. Can anyone check my math?

Where it ends up will set the amount of RAM that comes with it.

Thanks for all your donations!

Eric


Eric,

Your math looks good to me! $9K exactly.

I see Mark's original $1K offer + 6 extra $1K (62466, 62467, 62468, 62470, 62472, 62764) + soft^spirit cheque for $1K + $200 + $400 *2 (62603, 62695, 62698).

Have you tried downlaoding something like EVGAPrecision or MSI Afterburner

They will show you how your GPU is performing and allow you to overclock/underclock control fan speeds etc.

I've had a few recurring random lock ups varying from a few mins to half a day over the last couple of weeks myself.

I havent 100% tracked down the causes but these were the fixes.

http://setiathome.berkeley.edu/show_host_detail.php?hostid=5516356
Randomly freezing after months of working OK but with the screen still displaying. Tried various things, swapped GPUs and tried variouds combinations of the memory, upgraded video driver but still did it. Went in to BIOS and fixed the memory speed to match the RAMs spec and hasnt locked up since. I think the Auto overclock was pushing the memory too far.

Swapped GPUs (GTX470), upgrtaded video drivers and still the same. Checked and the fan speed on the GPUS had reverted to AUTO - I normally have it set to 100%.

[Edit] Forgot a third one that happened yesterday. One machine repeatedly locked up (clock stopped) but then unfroze after a few minutes - keyboard and mouse not active so couldn't find out what was happening. Rebooted and been OK since.

I suspect the gremlins are at work ...........
