Ubuntu - best way to force a switchover to GPU workunit?
(Message 1243476)
Posted 346 days ago by 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?) ===== details on my current setup ===== Fri 08 Jun 2012 01:44:03 AM EDT | | Starting BOINC client version 6.12.34 for x86_64-pc-linux-gnu Fri 08 Jun 2012 01:44:03 AM EDT | | Config: GUI RPC allowed from: Fri 08 Jun 2012 01:44:03 AM EDT | | log flags: file_xfer, task, file_xfer_debug, work_fetch_debug Fri 08 Jun 2012 01:44:03 AM EDT | | Libraries: libcurl/7.19.7 OpenSSL/0.9.8k zlib/1.2.3.3 libidn/1.15 Fri 08 Jun 2012 01:44:03 AM EDT | | Data directory: /var/lib/boinc-client Fri 08 Jun 2012 01:44:03 AM EDT | | Processor: 8 GenuineIntel Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz [Family 6 Model 26 Stepping 5] Fri 08 Jun 2012 01:44:03 AM EDT | | Processor: 8.00 MB cache Fri 08 Jun 2012 01:44:03 AM EDT | | Processor features: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts rep_good xtopology nonstop_tsc aperfmperf pni dtes64 monito Fri 08 Jun 2012 01:44:03 AM EDT | | OS: Linux: 2.6.32-33-generic Fri 08 Jun 2012 01:44:03 AM EDT | | Memory: 17.67 GB physical, 29.80 GB virtual Fri 08 Jun 2012 01:44:03 AM EDT | | Disk: 96.93 GB total, 80.49 GB free Fri 08 Jun 2012 01:44:03 AM EDT | | Local time is UTC -4 hours Fri 08 Jun 2012 01:44:03 AM EDT | | VirtualBox version: 3.1.6_OSEr59338 Fri 08 Jun 2012 01:44:03 AM EDT | | NVIDIA GPU 0: GeForce GTS 250 (driver version unknown, CUDA version 3000, compute capability 1.1, 511MB, 470 GFLOPS peak) Fri 08 Jun 2012 01:44:03 AM EDT | | A new version of BOINC is available. <a href=http://boinc.berkeley.edu/download.php>Download it.</a> == details on WU fetch attempts (cpu disabled hoping for GPU workunits) == Fri 08 Jun 2012 03:59:35 PM EDT | | [work_fetch] ------- start work fetch state ------- Fri 08 Jun 2012 03:59:35 PM EDT | | [work_fetch] target work buffer: 86400.00 + 864000.00 sec Fri 08 Jun 2012 03:59:35 PM EDT | | [work_fetch] CPU: shortfall 0.00 nidle 0.00 saturated 1299192.17 busy 155472.24 RS fetchable 0.00 runnable 900.00 Fri 08 Jun 2012 03:59:35 PM EDT | SETI@home | [work_fetch] CPU: fetch share 0.00 LTD 0.00 backoff dt 0.00 int 0.00 (blocked by prefs) Fri 08 Jun 2012 03:59:35 PM EDT | | [work_fetch] NVIDIA GPU: shortfall 950400.00 nidle 1.00 saturated 0.00 busy 0.00 RS fetchable 0.00 runnable 0.00 Fri 08 Jun 2012 03:59:35 PM EDT | SETI@home | [work_fetch] NVIDIA GPU: fetch share 0.00 LTD 0.00 backoff dt 0.00 int 0.00 Fri 08 Jun 2012 03:59:35 PM EDT | SETI@home | [work_fetch] overall LTD -46678.34 Fri 08 Jun 2012 03:59:35 PM EDT | | [work_fetch] ------- end work fetch state ------- Fri 08 Jun 2012 03:59:35 PM EDT | | [work_fetch] No project chosen for work fetch Fri 08 Jun 2012 04:00:35 PM EDT | | [work_fetch]: work fetch start Fri 08 Jun 2012 04:00:35 PM EDT | | [work_fetch] ------- start work fetch state ------- Fri 08 Jun 2012 04:00:35 PM EDT | | [work_fetch] target work buffer: 86400.00 + 864000.00 sec Fri 08 Jun 2012 04:00:35 PM EDT | | [work_fetch] CPU: shortfall 0.00 nidle 0.00 saturated 1299309.08 busy 155304.10 RS fetchable 0.00 runnable 900.00 Fri 08 Jun 2012 04:00:35 PM EDT | SETI@home | [work_fetch] CPU: fetch share 0.00 LTD 0.00 backoff dt 0.00 int 0.00 (blocked by prefs) Fri 08 Jun 2012 04:00:35 PM EDT | | [work_fetch] NVIDIA GPU: shortfall 950400.00 nidle 1.00 saturated 0.00 busy 0.00 RS fetchable 0.00 runnable 0.00 Fri 08 Jun 2012 04:00:35 PM EDT | SETI@home | [work_fetch] NVIDIA GPU: fetch share 0.00 LTD 0.00 backoff dt 0.00 int 0.00 Fri 08 Jun 2012 04:00:35 PM EDT | SETI@home | [work_fetch] overall LTD -46678.34 |

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.

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) |

Problem was resolved after two more reboots, as well as changing permissions on files in /var/boinc-client. The getaddrinfo failure still seems odd, I've never seen that fail before. |

Posted 449 days ago by 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 ?

Help needed - SETI@home communication non-responsive, Einsteim@home is OK
(Message 1195988)
Posted 460 days ago by 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?

502 Errors downloading SETI artifacts
(Message 1192351)
Posted 468 days ago by Ralph
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. |

Posted 468 days ago by Ralph
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.

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. Sun 05 Feb 2012 11:22:33 PM EST SETI@home Resetting project |

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 cruňches 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....

Posted 480 days ago by Ralph
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!

Are SETI@home workunits actually transmitted as .JPEG files? I'm really confused, I would think they would be sent as another MIME type, something more like "binary data", since they would have a different kind of file format? I've seen notes on various cell phone discussion about disabling caching and proxy server settings to enable that, but nothing is being discussed on the message boards about which ISP/carriers are trying to compress workunits and causing failures. I can run the boinc command line, but need a better idea about what commands to run to test things one command at a time.... |

After 4 months of bring offline, I'm trying to reconnect. I have a an 8-core i7 box with Nvidia GPU I manually aborted several workunits, then triggered the "1 workunit max per day" mode. Things still don't seem happy, I'm getting to the Internet through a tethered cell phone via T-mobile, and browsing and web surfing are all OK (but slowed to 10KBytes/sec while I'm over my wireless "quota") Here are the representative SETI messages: What log files or debugging can I enable to figure out why tasks are getting hosed on download? The only hardware thing I've done to the machine recently is add 12G of RAM, bring the total to 18G. My GPU is a 250-series, so I only have single-precision GPU, so Milkyway@home doesn't like me anymore.

Very strange. I'm seeing checksum errors, multiple times, for downloads. There is no "turbo mode" switch on my phone.but if they are trying to recompressing "image files", then I'm suspicious about that. What data type/mime type are the workunits sent as?

On a hunch, I also check "disable image file verification", on a chance that my ISP (T-mobile) is modifying image files. I hope this isn't the case, since I expect my ISP to transmit the data as it is, no matter whether it thinks it can optimize the data... |

Downloads appear to be running to completion now, but I'm still experiencing sporadic "download error" messages with actual work units, and they never show up in the "tasks" page. I was able to download the smaller files that apparently come with a new setiathome executable. Wed 25 Jan 2012 03:21:05 AM EST SETI@home Temporarily failed download of setiathome_6.03_i686-pc-linux-gnu: HTTP error Even when no download errors are reported, the tasks never show up in the tasks list of the client. Downloads for both Astropulse and "classic" S@H seem to be hampered. Wed 25 Jan 2012 03:38:30 AM EST SETI@home Started download of 23oc11af.5719.19672.4.10.159 |
