Posted 8 Sep 2010 by Questor Post: Also, just for fun, I have a gtx470 running on a XP/32 AMD 2.61 GHz duo at 1089 Gflops but my gtx470 running on a W7/64 i7 930 2.8 GHz only gets 726 Gflops. WTF? 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. John. |

Experiencing randow stops, system doen't respond to anything.
(Message 1031572)
Posted 7 Sep 2010 by Questor Post: 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. http://setiathome.berkeley.edu/show_host_detail.php?hostid=4841051 Randomly freezing after months of working OK but with the screen still displaying. 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%. Set to 100% and hasnt locked up since. John. [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 ........... |

My Machine knida overheated..........
(Message 1027466)
Posted 22 Aug 2010 by Questor Post: I have it set to shut down when the cpu fan speed drops to save the hardware, I had stupidly left some cables tied up with a rubber band which of course dried oit perished and snapped. Totally my fault whoops! I did exactly the same thing on an i7 ASRock MB. I couldn't work out why the RAC of the machine was low and tasks taking forever to complete. I installed the ASROCK monitoring utility which showed the CPU speed was cycling from 0 to 2.67GHz and keeping the CPU temperature at a constant 90C. Then I looked closely at the CPU fan and it had a power lead jammed in it. Removed the lead, CPU dropped to about 50C and the speed remained constant at 2.67GHz. It had probably been like it for a couple of weeks......... oops! |

modem question
(Message 1026761)
Posted 20 Aug 2010 by Questor Post: It is a Belkin G Router wireless one which I have had for a few years I can sympathise but not help much. I had a similar problem suddenly started with a Netgear DG834V2. Tried swapping with another borrowed Netgear DG834 and exactly the same. I have a work ADSL as well as home and now have a 3COM and a Zyxel installed and have not had the problem since. (The modem seemed to be working Ok - and could be pinged remotely but just periodically/randomly stopped sending data in and out) A restart made it work for a while. I assume some change was made at the exchange which the old modems couldnt cope with (and no newer firmware for this version) but the likelyhood of getting my ISP to admit/sort anything out was highly unlikely so I took the risk and tried new hardware. My ADSL is pretty poor - lucky to get 2Mb/s as we are a long way from the exchange. |

Posted 8 Aug 2010 by Questor Post: The times I cleared my ghosts was on Friday mornings just after the project comes back up. Just set no new tasks, run down what you have left and detach/attach and redo your app_info. By then most of my work was done and I don't lose too much. It also gives me plenty of time to refill. Sorry you are waiting on my ghosts. The recent DCF ups and downs have meant I've ended up with way to many WUs after initially having too few. I'm therefore stuck with either keeping the ghost users waiting or if I drop my OK WUs setting a lot of other users back to another long wait for a new wingman.

Posted 8 Aug 2010 by Questor Post: Mine has not been working since the first 3 day outage. I was wondering if I was the only one affected. :-S Exactly the same as you have here. No truncation of data on the page - just no data at all , only the page header. Been like this for over a week now and pending was around the 800K mark. I 'assumed' that the increase in pendings because of larger caches and ghost units was becoming too big a hit on the database so they put in some sort of restriction. Also had a quick check on a couple of machines last night for ghosts for the first time. 1. Reschedule showed 857 tasks in progress - web site 2020 2. Reschedule showed 882 tasks in progress - web site 2380 3. Reschedule showed 2800 tasks in progress - web site 4420 I'm going to have to do something soon to fix this but am loathe to disconect/connect because of losing what WUs I have. John. |

Multiple Cuda tasks on one GPU? Broke it.
(Message 1019532)
Posted 25 Jul 2010 by Questor Post: though no doubt the newer WDDM drivers still have some room to mature until they reach similar efficiency to the XP ones, and under heavy loading cache effects will come into play as well. Have you been running 3 tasks with the downlaod quotas in place? Just wondered what that does to the number of tasks you can download and whether you run dry during the outage. As far as SETI/Boinc is concerned you only have one device but are effectively getting through up to 3 times as many tasks but the completion times are for a single task. That should nicely confuse things? John |

Multiple Cuda tasks on one GPU? Broke it.
(Message 1019415)
Posted 25 Jul 2010 by Questor Post: I could be wrong, but I thought multiple Cuda contexts on one GPU is only possible under the WDDM driver model (Vista / Win7) and maybe only with cuda 3.0 & 3.1 builds (even less certain of that) Tried this out this weekend. I am currently running 3 tasks on a GTX470. The machine is using the downloaded stock apps (CUDA3.0) and is running on Windows XP 64 bit. Havent done any benchmarking yet - just testing that it runs OK. This is on an i7 920 with 2 GPUS and I have set avg/max ncpus to 0.4 which leaves 2 out of 8 free threads to help feed the GPUs (probably overkill as no maxed out threads and load times of about 20 sec per task). This is with drivers 19775 and 25721. John. |

Upgrading Cuda App - BOINC Trashing Units
(Message 1018807)
Posted 23 Jul 2010 by Questor Post: Guys, pardon this old non-Fermi character butting in but I think I might see a problem or two. As long as the new fermi app is referenced in app_info.xml as 609 then it wont matter - the workunit details will match with existing 609 WUs. OTOH if he has put an entry as 610 for the fermi card in app_info and removed the 609 reference then all 609 WUs will be trashed because no apps match. Possibly post app_info.xml? - it will be easier to analyze what the problem might be. (an example <workunit> and <result> section for CPU and GPU would help as well). Also have to watch that platform entries match - especially between CPU and GPU for when rescheduling. You might need a couple of very similar looking entries in app_info to cope with the possble combinations especially during the transisiton between the cards. John. |

Posted 17 Jul 2010 by Questor Post: Yes, connectivity has been restored and the project is on line. I'm still not sure what the problem was. Someone at UCB or CENIC must have fixed something, perhaps completely independently of our symptoms. Pings and traceroutes that had been dead in the water suddenly started going through. Thank you for the update on the situation Jeff. (Don't you just love technology :-) ) My machines are starting to report tasks but getting a lot of the following at present :- 17/07/2010 02:44:34 Project communication failed: attempting access to reference site 17/07/2010 02:44:34 SETI@home Scheduler request failed: Couldn't connect to server 17/07/2010 02:44:35 Internet access OK - project servers may be temporarily down.

Windows LAN connections...?
(Message 1016146)
Posted 16 Jul 2010 by Questor Post: My mobo has 2 LAN ports...... Are they both picking up valid IP addresses for your network (DHCP or static assigned)? If a port can't assign an address it will default to a 169.254.x.y address which may not get through your router. However, see this note about Windows 2008 from http://en.wikipedia.org/wiki/Link_aggregation Use on network interface cards Network interface cards (NICs) trunked together can also provide network links beyond the throughput of any one single NIC. For example, this allows a central file server to establish an aggregate 2-gigabit connection using two 1-gigabit NICs trunked together. Note the data signaling rate will still be 1Gb/s, which can be misleading depending on methodologies used to test throughput after link aggregation is employed. Note that Microsoft Windows does not natively support link aggregation (at least up to Windows Server 2008).[7] However, some manufacturers provide software for aggregation on their multiport NICs at the device-driver layer. Intel, for example, has released a package for Windows called Advanced Networking Services (ANS) to bind Intel Fast Ethernet and Gigabit cards.[8] Nvidia also supports "teaming" with their Nvidia Network Access Manager/Firewall Tool. Most PCs now have gigabit NICs (1000Gbit/s) whereas my broadband router is only 100Mbit/sec so one NIC is 10 times faster than needed anyway so it never gets overloaded. Some software e.g. Bitorrent clients will allow you to define multiple NICs to use but I cant think of much else that does. [Edit: Oops must have been typing at same time as Tim and Mark were] |
