Number crunching :
Separate work for GPU and CPU?
(Message 1296119)
Posted 219 days ago by S@NL - eFMer - www.efmer.eu/boinc
I've noticed that 7.0.28 will keep asking for GPU work until it gets to about 1.25 days more than my min + additional setting, and even at that level it will ask for a few thousand seconds of GPU work. I use local preferences of 6 and .01. I don't get much CPU work until it gets to 7.25 days of GPU work per BOINCTasks' sum of estimated times. You can intervene and temporarily turn off GPU fetch in the SETI@Home project preferences (website). I have do this about once a week to rebalance the cache. Of course, that would affect all of your hosts unless you are using venues (home, school, etc). That's what I've been trying to automate. That's when you don't get any work at all. No CPU that way. But I expect you get no problems if you have one GPU. |

And set at least the <sched_op_debug> logging flag in cc_config.xml so that you can see exactly what's going on when work is requested/received. Done: 68079 SETI@home 17-10-2012 12:19 [sched_op] estimated total NVIDIA task duration: 7555 seconds 68078 SETI@home 17-10-2012 12:19 [sched_op] estimated total CPU task duration: 0 seconds 68077 SETI@home 17-10-2012 12:19 Project requested delay of 303 seconds 68076 SETI@home 17-10-2012 12:19 [sched_op] Server version 701 68075 SETI@home 17-10-2012 12:19 Scheduler request completed: got 22 new tasks 68074 SETI@home 17-10-2012 12:18 [sched_op] NVIDIA work request: 6868.66 seconds; 0.00 devices 68073 SETI@home 17-10-2012 12:18 [sched_op] CPU work request: 2080512.00 seconds; 8.00 devices BOINC request work and gets GPU work just above the value needed. Gets 7555 needed 6868. But there I expect it goes wrong. 687 is 76 for GPU to handle. So it gets just about the GPU it needs and hoovers just below the threshold. Is should get at least number of GPU * scheduler interval. + something extra. 9 * 6 * 60 = 3240 it gets 687. I see this line: 68074 SETI@home 17-10-2012 12:18 [sched_op] NVIDIA work request: 6868.66 seconds; 0.00 devices Does it know how many GPU tasks are running ????? |

After correction that problem in BoincTasks, the results are still the same. No GPU work. After changing the buffer from 2 -> 3 I got way over 1000 WU in a singe hour. All GPU of course. Now at 3 days. 67320 SETI@home 17-10-2012 10:56 Scheduler request completed: got 0 new tasks 67319 SETI@home 17-10-2012 10:56 Reporting 1 completed tasks, requesting new tasks for CPU 67318 SETI@home 17-10-2012 10:56 Sending scheduler request: Requested by user. It is getting no CPU work. The 6.12.33 has plenty of CPU work and gets is regularly. |

But I think I see what's going wrong. Maybe that is.... V7 reused Connect every Additional work buffer -> Minimum work buffer. Additional work buffer. So I set the Additional work buffer as in V6, but I probably have to use: Minimum work buffer in V7. |

And what do you see in message log? Does BOINC client asks for CPU work and doesn't get it or it doesn't ask for CPU work? As you can see, it asks for CPU work only. I was building an additional in BoincTasks. If GPU work > 2 day and CPU work < 0.5 day set buffer to 2 days. That's when I noticed the buffer staying on 2 days for a couple of days and no CPU work except for some AP work. |

I've notices the CPU is not getting any work at all. I know the GPU gets work first. But I set a Buffer for 5 days, no CPU work, but the buffer is filled to 5 days. Next I dropped the buffer to 2 days. BOINC is requesting CPU work. Stayed there for a couple of days. The buffer fills to 2 days and stays there. Now I set the buffer back to 3 days and I immediately get new work. And a lot of it, of course all GPU. This happens with 7.0.28 and 7.0.31. At 2 days 64836 SETI@home 17-10-2012 09:03 Scheduler request completed: got 0 new tasks 64835 SETI@home 17-10-2012 09:03 Reporting 5 completed tasks, requesting new tasks for CPU 64834 SETI@home 17-10-2012 09:03 Sending scheduler request: Requested by user. 64874 SETI@home 17-10-2012 09:13 Scheduler request completed: got 42 new tasks 64873 SETI@home 17-10-2012 09:13 Requesting new tasks for CPU and NVIDIA 64872 SETI@home 17-10-2012 09:13 Sending scheduler request: Requested by user. 64977 SETI@home 17-10-2012 09:18 Scheduler request completed: got 72 new tasks 64972 SETI@home 17-10-2012 09:18 Reporting 3 completed tasks, requesting new tasks for CPU and NVIDIA 64971 SETI@home 17-10-2012 09:18 Sending scheduler request: To fetch work. |

V 1.6 with some minor fixes. http://www.efmer.eu/forum_tt/index.php?topic=974.0 According to the developer, the AP application can't give a progress.... But I made some changes anyway. |

It may be a system glitch. I've seen above 100 on all my systems, 360 on one I believe. 1.5 GByte download in one day on a single machine. |

The client went wild.... 1000 WU in a single hour, going over 7800 WU's, way over the set value. Another computer got 550, 800 and 900 in 4 hours. And after that of course all the work is gone. |

V 1.5 http://www.efmer.eu/forum_tt/index.php?topic=974.msg5946#msg5946 1) If you can send me the file every time it's update I can check what's going on. All files that appear while processing. 2) OK. |

The problem is in the inconsistencies. \n is sometimes a new line \r\n is the Windows way. But writing it to file gets \r\r\n the \n -> \r\n I now remove all \r before writing, produces \r\n. |

What I see so far is that the 6xx series is actually slower on the g. It has more cuda cores but they are less capable. The Beta Z series suggest that the 6xx series will be a bit faster with that program version. |

Are you using 1.4 ? Simply unpack the zip in a folder and run it. Sometimes something unexpected happens. Use explorer and try to open this folder: C:\videocardtest\SetiPerformance_32_64_1_4\zip\x41g\ Try opening C:\Users\Jim\AppData\Roaming\eFMer\SetiPerformance and check what is in slot0. Helping me solve this will help others and will make a better V 1.5 |

This has me confused.. Just for fun I tried this on two computers both with GTX 260's and both comp's came back at .5 as the optimal setting.. So I decided to actually try it on one comp and so far it is a tiny bit faster running at .5.. I'm lucky in that I have a group of work units that are all the same day and angle.. It crunched 8, two at a time, at 6:35 each.. And so far it's crunched 4 or 5 more, 1 at a time, at 3:44 each.. Normally it's even slower running more than 1. My guess it got something to do with feeding the GPU. Maybe the CPU doesn't got the time to feed the GPU properly. And with 2 CPU tasks it may get more time allocated. This means leaving a CPU core dedicated to the GPU feeding may help. Or set a higher priority on the feeder task. You can try this program: http://www.efmer.eu/forum_tt/index.php?topic=198.0 and set the priority higher. |

OK: Added the progress on state.sah and I will add the pulse as well. The window position is now stored. A file log is created: result.log, SetiPerformance.log logs the startup process. The GPU activity is only shown on NVIDIA GPU's. Check out TThrottle 6.10 and check if the activity indicator (G) right one is moving according to the GPU use. If that works and you want it, I will add it to this program. |

Doesn't write anything. stderr.txt and result.sah are not updated. Is there a parameter to force check pointing? |
