Edit:Six completed now, the new ones since yesterday are two xp and one win7 so still no 10s. One out of ten completed is Win 10 but given the preponderance of Win10 computers compared to 7's the evidence is stacking up. |

I would certainly say that the minimum memory should be 2GB/core these days. The new RAM arrived. These numbers are not typical, because I just booted the machine. $ free I have not noticed the need for it with CPDN, but some WCG tasks were using over 8% of the RAM (each) and there are other tasks in there too. It used to be my machine ran with about 10% of RAM used for processes, 5% for (output) buffers and 80% for (input) cache. The cache stores recently read stuff and often some disk read-ahead. It seems as though nothing has swapped yet. ;-) ![]() |

My figures with 2 tasks running on a dual core machine, only other things running are browser (just one tab open) and email. I have 4GB of ram on this machine but some is used by video. Uptime is a couple of weeks. total used free shared buff/cache available Mem: 4029908 3076436 129192 370284 824280 353820 Swap: 5859324 1277884 4581440 |

My figures with 2 tasks running on a dual core machine, only other things running are browser (just one tab open) and email. I have 4GB of ram on this machine but some is used by video. Uptime is a couple of weeks. After running for a bit more than a day, my memory usage is now: $ free total used free shared buffers cached Mem: 16254616 10984588 5270028 53092 707676 6477604 -/+ buffers/cache: 3799308 12455308 Swap: 4095996 6152 4089844 It has used a little bit of the swap space. Early this morning, about 15 GBytes of RAM were being used. This was almost certainly because a fairly complete backup runs every morning around 3AM when I am asleep. The space used as buffers must be written out before it can be re-used. The space used as (input) cache does not have to be written out ever, so can be re-used with no IO at all. And if input is requested from a disk drive, but is already in the cache, likewise, no IO is required, just resetting some memory-mapping registers. ![]() |

My Win7 64-bit machine is still going strong on three 797's and two 798's after 4 to 9 days, with no failures on either. I don't think that is a coincidence. #797 is now showing 43 tasks completed of these just 10 are with Windows10. I checked on a similar number of machines to get an estimate of how many are running Win10 and of those I looked at it was a little over half so Win10 having a problem with these tasks is looking significant statistically. It would be interesting to know what if anything is different about the win10 machines that are succeeding v those that are crashing these tasks. I don't know how many if any of these win10 machines are really Linux ones in disguise. My most advanced task doing this is just over 40% complete. |

I don't know how many if any of these win10 machines are really Linux ones in disguise. My most advanced task doing this is just over 40% complete. One way to possibly determine Windows vs. Linux with Wine is the benchmark scores. The Floating Point scores in particular are way low in Wine compared to actual performance and capability of the CPU. So a Haswell 46xx might have a floating point score of 1100 where it should be in the 4000s (or something like that) in Windows. I'll modify the floating point score in client_state so that task estimated times are better, but I can't imagine there are many people doing that. |

#797 is now showing 43 tasks completed of these just 10 are with Windows10. I just completed a 798 on Win7, and another one will complete in five hours (with no failures). I didn't get any on my Win10 machines, but they are probably the same as the 797s. |

So a Haswell 46xx might have a floating point score of 1100 where it should be in the 4000s (or something like that) Thanks George, I will have to compile a table based on Linux machines so I know the ball park figure to expect and if out by a factor of >3 for instance assume an imposter. (Some of my recent tasks, the time is out by a factor of more than ten! I know I don't have the fastest machines but estimates of 186 days when worked out using percentage completed against time taken makes it under 15 days is pythonesque (and I am not referring to the programming language!)) |

Would you be able to get a guess on the OS from the sec/ts data? One of the 797's that I got and failed was averaging 5.95sec/ts and got to the 2nd trickle on my faster i5 under Win10 before failing. |

There is negligible difference in speed between a PC running cpdn natively in Windows vs. the same PC running cpdn in Wine under Linux. At least that's what I've seen. It's just the benchmark that's screwed up for some reason. |

and like buses, #809 brings us another 8190 tasks, again part of the same work. |

Boooo another "Signal 11 received: Segment violation" on a "wah2_safr50_a0vl_201612_24_790_011752393_0" I thought these were ok. |

It's partly the model, and partly the computer. |

Four of my boxes are upchucking on downloads of SAM50 tasks of different flavors. One wonders when those 'scientists' will get their act together ... "We have met the enemy and he is us." -- Pogo Greetings from coastal Washington state, the scenic US Pacific Northwest. |

Batches 810 and 811 bring over 11,000 new SAM50 tasks into the hoppers. |

Boooo another "Signal 11 received: Segment violation" Another safra/790 with Segment violation. Pleased I have run out of these now.. Are the sam50's OK? |

Are the sam50's OK? I have 4 sam50 errors and 19 completed. That is better than the safr50's, though I have not counted them all. |
