21) Message boards : Number crunching : Strange PC hang, using Nvidia GPU (optimized) (Message 1242654)
Posted 7 Jun 2012 by Profile Francesco Forti
Or it could be just a tired power supply or graphics card getting close to failure.

Ok, I was thinking the same thing.
But later I have noticed that "black screen and restart" is appening every time I suspend work using Boinc icon in the appliction bar (suspend all or suspend GPU). As I restart, after some seconds I get the problem. Some times even if I exit from boinc and restart it. Seconds, I think, are the ones necessary to prepare the data for GPU and send data to it.
I stop GPU because when I use my PC with a VOIP application, sound is not good (I listen good but my interlocutor doesn't) and I have seen that if I stop BOINC (or olny GPU) the sond is good. As I restart the GPU task, I get the "black screen and restart". And at restart I get a new stop. I never have this in orher situations. I see that if PC is autorestartng (after maintenance) I don't have problems.
So I think that can be something in the suspend/restart in the 7.0.25 version

Happy end? I hope.
Everything is running fine. CPU and GPU too.
Maybe it was something about task "01jl10ac.26305.8251.13.10.90" and "295.73 drivers" with optimized apps.

I don't know if someone is able to replicate what happening (same card, same driver, same pgms, same task) but if someone is having similar problems, he can try to updaate NVIDIA Drivers.

0) I'm running seti@home since 2000, as you can see
1) it's the firts time I see what I' tryng to explain now

I'he got an infinite loop of "black screen and restart".
I have seen that PC hang and restart happens some minutes after restart.
So I had some time to try something.
I have tried to stop boinc (exiting as soon as it starts)
This is working.
PC continue to work and doesn't restart any more.
So this was a strong suggestion to someting connecterd with seti (the only one project I run)
As I see boinc running, I have to wait some seconds in orded to see next hang, so my olny two neurons told me that may be it was something about GPU.
In this moment Boinc is stopped so I can write you.
later I will do some test but I prefere to wrte someting now, just to help you in helping me (and perhaps also other cruncers).

host is http://setiathome.berkeley.edu/show_host_detail.php?hostid=2693912

4 CPU + 1 NVIDIA GeForce GTS 250 (1023MB) driver: 295.73
Microsoft Windows XP
Home x86 Edition, Service Pack 3, (05.01.2600.00)

I'm running the latest lunatics optimized application (Lunatics_Win32_v0.40_setup.exe)

Next try is to update NVIDIA drivers and I will try to determinate the exact GPU Task involved

News at next boot
======
Update: now "I am NVIDIA GeForce GTS 250 (1023MB) driver: 301.42"
Boing is runnig fine but I have suspended GPU.

Task suspended seems to be
Computer: Juppiter Project SETI@home Name 01jl10ac.26305.8251.13.10.90_0 Application setiathome_enhanced 6.10 (cuda_fermi) Workunit name 01jl10ac.26305.8251.13.10.90 State Waiting to run Received 27.05.2012 01:32:32 Report deadline 12.07.2012 13:01:32 Estimated app speed 2.81 GFLOPs/sec Estimated task size 3'301 GFLOPs Resources 0.04 CPUs + 1 NVIDIA GPU CPU time at last checkpoint 00:00:38 CPU time 00:00:39 Elapsed time 00:04:07 Estimated time remaining 00:14:57 Fraction done 21.439% Virtual memory size 79.12 MB Working set size 78.07 MB Directory slots/2 Process ID 2820


I will try to resume task and see if pc is still hanging
24) Message boards : Number crunching : "Lost Task" (Message 1235741)
Posted 24 May 2012 by Profile Francesco Forti
In theese days I see a lot of

Of course I see 20 lost task resent followed by 20 Already have task
This mainly on two hosts. [Edit_ now three].
25) Questions and Answers : Preferences : Not uploading completed WUs (Message 1231976)
Posted 14 May 2012 by Profile Francesco Forti
Completed work is reported at the first of:

1) 24 hours before deadline.
2) Connect Every X before deadline.
3) 24 hours after task completion.
4) Immediately if the upload completes later than either 1, 2, or 3 upon completion of the task.
5) On a trickle up message.
6) On a trickle down request.
7) On a server scheduled connection. Used, but I am not certain by which project.
8) On a request for new work.
9) When the user pushes the update button.
10) On a request from an account manager.
11) Report immediately every task, if "No new Task" is set.
12) Report immediately if CPU or network time-of-day override starts in the next 30 minutes. (BOINC 7.0)
13) When minimum work buffer is reached. (BOINC 7.0)


I think that an other point can be as soon as a "high task priority" is uploaded.

27) Message boards : Number crunching : Communication problem (Message 1201632)
Posted 2 Mar 2012 by Profile Francesco Forti
I don't know if someone in Berleley have closed (a little) some tap but what I see now is that:
1) data comm graph isn't allways at max speed
2) there are 256,832 results ready to send
3) my hosts have the max of results to crunch
4) I don't have any transfer pending

So this is the ideal condition. :-)
Of course if it is so for everyone!

Is it so?

Posted 28 Feb 2012 by Profile Francesco Forti
From yesterday, 27 feb, the speed of my connection is 3 times faster.
I didn't make any change here and the green line in Graphs for gigabitethernet2_3 was allways at max level.

It's just like someone closed a litte bit the tap :-) optimizing the data flux

Posted 26 Feb 2012 by Profile Francesco Forti
Thanks for the C10K info.
Avery client host can handle two DL in parallel and I use to see from 5 to 20Kb/s speed each, if good, but sometime less than 1.
With BoincTasks I can see all the DL/UL job of my 8 hosts here (other are far)
When berkeley is out of work and the green cricket line is falling down, I see that my DL are 150 to 200 Kb each and so I thing that if you at Berkeley make some filter in order to have only 10'000 clients for each of your DL server, bay be the queue will be used better.
I don't know if you have some "tap" in your communication equipment but if you have, try to set at ~10'000 connection.

Is it possible?

Posted 26 Feb 2012 by Profile Francesco Forti
As we can see here when everything is working at max speed in berkeley, we reach the maximum (Avg: 93.49 Mbits/se) and the green graph is flat.

But I can see also that my DL is very very slow.
In theory I can DL at 100Mb, but I see I DL at 30~50Kb

Result is a lot of DL open (hundreds), going slow.

When for any reason Berleley is out of work, I see that suddenly all my pending DL run fast at maximum speed.

So I think that must be someting wrong in how the commnication line is used.
We are too much, trying to pass a little door as in a cinema when someone is shouting "fire!".

Maybe a better usage can see anyone wait for a tiket and then pass data at maximum speed.
Or any other algorithm that can handle better the queue.

Some weeks ago I have seen some posts here about proxy setting. I have tried and for some day I had a good speed. Is this option still valid?

Bye
Franz

Posted 26 Feb 2012 by Profile Francesco Forti
I had a lot of computational errors with 295.73 driver but only in one Win7(32) host.
No problems wih 295.73 driver on XP hosts.
I have installed Lunatics v0.39 everywhere and now I don't see errors in the Win7(32) too.

35) Questions and Answers : Wish list : Proxy configuration using BOINC account preferences (Message 1173446)
Posted 24 Nov 2011 by Profile Francesco Forti
Often the proxy settings are required to get to the internet at all, and in those cases, BOINC cannot get to a central location to get the proxy information without the proxy information already input in the first place.

Yes, I understand.
In this moment the problem mentioned here http://setiathome.berkeley.ed/forum_thread.php?id=66119 can have a solution using proxies because we have only some (or a lot of) packet loss but some communication can be established.
So it's possibile to move the information "use this proxy" (the proxy that I choose) from central server to clients. Of cours if that proxy goes down forever, I will change data ony locally, on clients.

This will probably not happen.
Maintaining list of proxies is beyond what BOINC could (or will and should) manage.


Wy?
We (users) have to set proxy data, as we can do locally just now.

Francesco,
The Proxy is not just for SETI. In 2009, after the Iranian elections, the regime there cut off internet access through many routes. In order to get around this the people used many proxies in many different countries to get their message out. As fast as the regime would block one IP the people would switch to another proxy and would be good to go again for another little while.

If, for some reason, you are trying to reach a website in another country and find a bad or blocked router in the path your IP uses then you can go to a proxy in another location to get around that bad router.

Ok, thank (I know it).
I was only asking why to select a particular country.
By the way, I have written a post in "wish list" to suggest a proxy configuration for all our hosts in boinc preference (in web account configuration).
See: http://setiathome.berkeley.edu/forum_thread.php?id=66175#1172447
Of course this neeed a change in web pages, central database and local client (boinc manager)
It's not necessary if someone have only one host, near him, but can be good if someone have 20 hosts far and unattedend.

Refferring to this thread: http://setiathome.berkeley.ed/forum_thread.php?id=66119
and having the need to change proxy data in all my host (near and far) I think that could be usefull to have the possibility to set proxy data in on central point (BOINC preferences, in the communication part) so that this is applied to all our hosts, at first contact.
I know that "These apply to all BOINC projects in which you participate" and I don't know if this can be a problem or not but can be usefull to bypass actual problems (packet loss) communicating with berkeley.

Posted 18 Nov 2011 by Profile Francesco Forti
I have used various proxies which I got from http://www.xroxy.com/proxylist.htm. You can filter by country and other items to find the one that works best for you.

Ok, it's clear .. but what is the meaning of the "country" selection?
The proxy we are speaking of (69.163.96.2:8080) is in California, so I'm sure to bypass the problem in between. Why should I use a Swiss, Austrian, German, Frenc or Italian proxy?
40) Message boards : Number crunching : More HE Problems ???? (Message 1171936)
Posted 18 Nov 2011 by Profile Francesco Forti
Here from Switzerland, I had a strong slow down of seti communication and a lot of packet loss pinging seti server.
5 minutes ago I have seen this thread and I decide to use 69.163.96.2 HTTP proxy.
Now I'm downloading ad full speed from all my PC's.

Can I use it always?
