1) Message boards : Number crunching : Recommendation needed: Linux proxy server application to defeat GPRS image compression (T-mobile) (Message 1435230)
Posted 29 Oct 2013 by Profile Ralph
I use a T-mobile data service from time to time, but they insist on compressing data that looks like images. This causes SETI@home workunit downloads to be compressed, which makes them unusable.

It would be nice if workunits were downloaded with a tamper-proof secure connection, such as HTTPS.

Is there a method I can use to set these HTTP request headers that the SETI apps make?

I could get a second GPU/graphics card, what's the sweet spot for price/performance these days?

Let's assume I'd rather spend <$200 on a graphics card, and not $300-400.

I'm assuming I should stick with nVidia, and I'd like to run multiple monitors on the original 2009-vintage 250GTS (and probably the new card, as well).

In 2013, I'm assuming I'm looking for a double-precision GPU with 2G VRAM, and hopefully 256 or 512 CUDA cores - so I can do Milkyway@home and other projects I've been locked out of since 2011.

Thanks for the tips!

This is likely a 2009-vintage card, 512M RAM is all I'm going to have with it.
I did find Version 294.75 on the NVidia site, under "old drivers", but 266.58 no longer seems to be available, so I'm trying 319.32 (the latest certified version) - the Ubuntu 10.04 official repositories don't seem to have anything newer than what I already have.

After months of not being able to to GPU processing on Linux, I found a post that noted a simple workaround, detach from the project and re-attach. This seemed to work fine, but I'm also getting some "pathological" work units that Astropulse 6 seems to chokes on:

(there are hundreds of these 'restarting/exited with zero status' sequences for the workunits that are 'bad')

My questions are:
1) Is this a GPU specific problem?

2) Where can I get more details on the problem?

Other posts seem to mention changing parameters for things like loop unrolling, but I'd hope that the science clients be able to automatically configure this if my GPU requires changes.
6) Message boards : Number crunching : Optimized client advice for BOINC 7 / Ubuntu 10.04 (Message 1267029)
Posted 3 Aug 2012 by Profile Ralph
I'm experimenting with BOINC 7, and looking for advice on these topics:


  • Finding accurate documentation on using BOINC 7 with optimized SETI clients (NVidia GPU, hoping to use an optimized OpenCL or nVidia client for x86_64)

  • Which optimized clients are compatible with Ubuntu 10.04.

  • Configuring application settings so that a missing client doesn't automatically cause workunits to be deleted.

    (I'd rather BOINC suspend work on them than delete them, to give me time to respond to a misconfiguration)



I tried the Lunatics x41g build, but it doesn't help as much as I thought it would. I get the impression that performance on SSE3-capable processors is also helped by using an OpenCL client. My GPU is an nVidia GTS 250

Here's what lspcishows:

02:00.0 VGA compatible controller: nVidia Corporation G92 [GeForce GTS 250] (rev a2)

www.streamcomputing.eu/blog/2011-12-29/opencl-hardware-support/ suggests that since I don't have the nVidia 260, I won't have the compute capability 1.3 support needed for OpenCL.

8) Message boards : Number crunching : Ubuntu - best way to force a switchover to GPU workunit? (Message 1243476)
Posted 8 Jun 2012 by Profile Ralph
I'm still running SETI@home on Ubuntu 10.04 LTS - 64bit.

After resolving my ISP issues that only affect the SETI@home Boinc client (by switching ISPs), I'm interesting in processing workunits on the GPU.

What are the first steps that are recommend? I was processing GPU workunits before, but I reinstalled so many times trying to fix the ISP problem that I don't think I have any optimized clients left...

Shall I jump right into BOINC 7 - install an optimized client (is that even necessary?)

Posted 1 Mar 2012 by Profile Ralph
I'm running BOINC on Ubuntu 10.04 LTS - haven't been able to download the new binaries or any SETI workunits via the "normal" mechanism since October 2011.
BOINC complains that it count download the files it needs to run the SETI science application.

I've even tried using a Windows XP vm image, and get identical failures.

Oddly, I can download the .PNG graphics files and SETI client using the Coral CDN (adding nyud.net to the end of a URL), so if I could find a proxy server JUST for SETI connections I'd probably be OK - does the BOINC client allow you to use a proxy for some projects and not others? For now, I'm only downloading Einstein, but even if any transient SETI server problems are fixed, I don't think SETI will ever work for me again. After over a month of trying stuff, it's very frustrating.

nyud.net isn't quite the kind of proxy server I can use to download workunits, but it got the job done for the application download on a different platform. And installing BOINC using the Ubuntu app store has always worked fine.


This PC was off for 4 months due to a move, in the new location it only has Internet access via a "tethered" mobile connection over the USB port, which works with every other BOINC project, and internet access sgenerally, just not Seti@home.

1) Can I force an HTTPS connection to the SETI at home server that bypasses any packet sniffing/reformatting my ISP might be doing?

2) Is there a "public VPN" provider I can use to jump over my wireless carriers presumed clueless mangling of packets? (I've tried turning "image verification" off, to no avail)

11) Questions and Answers : Unix/Linux : [linux] BOINCmgr hangs while connecting - suggestions? (Message 1200317)
Posted 27 Feb 2012 by Profile Ralph
I installed new BOINC client/manager apps, in an attempt to get S@H working.
(I get persistent HTTP download errors, and no workunits for SETI at home since Jan 2012. I run PrimeGrid and Einstein on my Box - which runs Ubuntu 10.04LTS with zero problems.)

I went from 6.10.45 to 6.12.34 (x86_64-pc-linux-gnu) and all seemed well until I stopped the science apps from the boinc_mgr gui, Upon reboot, nothing is working.

Normally, my init scripts restart BOINC, but now I have no running science apps, and boincmgr can't connect to the client, as if it's not able to complete its startup and start listening.

Here's what "ps" shows:

boinc 12996 0.0 0.0 94096 17608 ? SN 06:39 0:00 /usr/bin/boinc --check_all_logins --redirectio --dir /var/lib/boinc-client
ralphw 13280 98.4 0.1 333656 24080 ? Rl 06:41 2:15 /usr/bin/boincmgr

1) boinc should be running as the "boinc" user
2) The boincmgr application runs as whoever is logged in

So why can't they connect? If there's a permission problem, what else do I need to clean up? (I may have run boinc as root during my earlier testing of the new BOINC binaries. Shouldn't rebooting clean things up, or is there some manual step I must run)

12) Questions and Answers : Unix/Linux : Help needed - SETI@home communication non-responsive, Einsteim@home is OK (Message 1195988)
Posted 16 Feb 2012 by Profile Ralph
Need help understanding why SETI@home still not sending workunits.
I had connectivity problems in January, but those were resolved when my wireless provider dropped the bandwidth limiter in Feb.

einstein@home workunits are humming along, but I've never ever been able to connect successfully to the seti@home servers to download workunits since I reconnected my SETI rig to the Internet after being offline for 4 months.

What settings can I change to reliably diagnose and fix the problem?

I've tried turning off image verification (no change). In the past, I had HTTP 502 errors, so I manually grabed the client programs & supporting image files, using the Coral CDN (add .nyud.net to the end of the host part of the URL), but that doesn't work for workunits.

When I reset the project, it tried reconnecting normally to re-download the client, but kept failing with truncated files. Are there still problems in reliably connecting through the network at Berkeley? Do I really need a proxy server? The problem I have now seems more fundamental, if the error messages are to be believed.

Is the "not reporting or requesting tasks" a message from the seti@home server, or from my client?

Is there a reason this is so difficult?

I was able to download the executables and most of the support files using the nyud.net hack (listed above).

This does not work for workunits, since the BOINC setup must do that.

How can I convince the SETI@home server boinc2.ssl.berkeley.edu to let me have those? Everything I try to download directly from it suffer the same 502 fate.

It seems like a bad proxy should affect ALL projects, but einstein at home and others are working fine.

OK, downloading using those link do NOT work.

(It seems identical to the link that the BOINC client is using.)

How can I obtain the binaries? I tried these three types of link:
Main address:
http://boinc2.ssl.berkeley.edu/sah/download_fanout/setiathome-5.28.x86_64-pc-linux-gnu
Server 1: http://208.68.240.18/sah/download_fanout/setiathome-5.28.x86_64-pc-linux-gnu
Server 2: http://208.68.240.13/sah/download_fanout/setiathome-5.28.x86_64-pc-linux-gnu

I have connectivity, ping to 208.26.240.18 returns a response, no dropped packets.

What seems to work is using the Coral CDN, bypassing the SETI@home site altogether. So http://boinc2.ssl.berkeley.edu.nyud.net/sah/download_fanout/setiathome-5.28.x86_64-pc-linux-gnu downloads OK

My theories are:
1) My ISP is putting some half-assed, broken proxy server between myself and the servers at Berkeley.

2) SETI's network infrastructure has blacklisted my computer somehow.

The problem is, once I download the binaries, how can I be sure that workunits will download properly? Can I force HTTPS connections or otherwise work around my ISP's brain-dead proxy?[/b]

After Feb 3rd, my cell phone's ISP relaxed the bandwidth restriction.
I can download and completed Einstein@home workunits, but SETI@home still has a problem, I've been unable to download a workunit (or the SETI client in that whole time.

I turned off GPU processing, turned off astropulse, but even small workunits aren't being downloaded, so I'm not sure what to try next. I've tried resetting the project, detaching and reattaching.

It seems that I'm stuck trying to download the SETI client itself. I've alternatively hit the .13 and .18 servers, with no change in results.

HTTP 502 errors are noted whether I use wget or the BOINC setup:

I've tried manual download as well, and it returns a 502 HTTP error.
Einstein at home is running fine, but the BOINC/SETI@home combo can't
download:
    .png files
    workunits
    updated binaries and the files with names ending in _COPYING, etc.



What should I try next?

Also, based on advice in other threads in 2011, I've done a "reset project", which force a new download of .png files.

Are there any SETI Server problems that would cause this? Should I try downloading the files manually with wget? It seems like the problems are BOINC communicated with the SETI project servers.

After my mobile ISP lifted my data rate caps, I can now download Einstein@home workunits.

However, SETI is still stuck in "HTTP error land" - this has been going on for nearly two weeks now... I set my BOINC download rate to 200 kbps , and Einstein at home cruƈches just fine.

Is there a way to force download of a CPU-only SETI@home client? Seems prudent to rule out all the other possible issues....

Thanks!

The BOINC client I run on Ubuntu Linux is trying to download several things:
    climateprediction workunits
    seti@home workunits
    a new seti@home application


None of it seems to be working properly

I've enabled additional debug logging by changing a few zeros to ones, but don't see any extra output. Is there a log file/directory I should be looking for on Linux, that shows the BOINC manager and BOINC Apps starting up?

The BOINC client tried downloading some .vlar (smaller SETI@home) workunits.

I seem to be getting consistent HTTP Errors, but it seems unlikely that I'd be getting this many actually network errors, unless something is seriously wrong..

Web browsing works without a hitch, so I'm not sure what the problem could be.
Is there a manually downloadable workunit I can try running, even if I don't get credit for it? I want to isolate where the error is actually occurring.

Suggestions welcome,
Thanks!
