Does this help? (I have not tried it yet.)I will have a look soon. What I would really like is something that shows cache usage by application in much the same way that top shows cpu usage. Thanks. I think that is a good first indication. It is not surprising that they use a lot of cache. I had assumed the slow down was the writing to swap file because of lack of RAM. |

I had assumed the slow down was the writing to swap file because of lack of RAM. With my 64 GBytes of RAM, I seldom use the swap file at all. Now with the OpenIFS stuff, if it ever gets into production, it may use more of course. That link I showed is not very useful, at least as far as I can tell. I found another way to get at this. Right now I have my main machine running (the one with 65GBytes RAM and 16384+512K bytes memory cache). It is running four N216 CPDN tasks and Four WCG tasks (two ARP1's and two CPN1's). I found something I downloaded, the perf command, and ran it for while. It looks like one can learn a lot with it. The manual page helps and running perf --help should help too. Running two N216, 5 WCG, and one rosetta localhost:root[/home/jeandavid8]# perf stat -aB -e cache-references,cache-misses ^C Performance counter stats for 'system wide': 12,019,648,573 cache-references 6,494,633,179 cache-misses # 54.033 % of all cache refs 23.651410187 seconds time elapsed Running no CPDN, but some WCG localhost:root[/home/jeandavid8]# perf stat -aB -e cache-references,cache-misses ^C Performance counter stats for 'system wide': 3,727,867,972 cache-references 1,368,824,386 cache-misses # 36.719 % of all cache refs 14.735167255 seconds time elapsed Running only boinc client, no tasks: localhost:root[/home/jeandavid8]# perf stat -aB -e cache-references,cache-misses ^C Performance counter stats for 'system wide': 128,714,374 cache-references 5,195,723 cache-misses # 4.037 % of all cache refs 25.357159122 seconds time elapsed |

Yeah, Checked some out and I've seen some trickling. Jumped the gun with the e-mail, and my errors on the two I downloaded were segmentation faults instead of namelist errors. And the hadcm3s has historically had a relatively high failure rate with segmentation faults. |

I'm using Ubuntu 20.04 Server 64bit with the 32bit libraries as mentioned in the other thread. Six of these running OK here so far four have produced trickles and uploaded zips. Off to work soon, when I get back will poke around to see if I can find any common factors in the machines with failures and or those that are getting far enough to produce trickles.

Off to work soon, when I get back will poke around to see if I can find any common factors in the machines with failures and or those that are getting far enough to produce trickles. So far, error types are missing libraries, seg fault, process creation error (computers with this seem to be crashing everything as they do with missing libraries) and bad cpu type error (all on machines running Darwin. As to spotting any pattern, nothing has emerged from the noise yet. |

Oh good! It is not just me. A long way from being just you. Sadly I am not finding enough data to work out whether it is just some work units that have the problem or whether there is anything about the computers involved. So far I have seen that both Intel and AMD machines are implicated in the seg fault violations but both also have some machines like my own that have produced trickles. This is true across both Darwin and Linux computers and certainly both Ubuntu and Debian have tasks sending trickles and failures of this type. Yours in the only Red Hat machine I have looked at so a lack of data there. I don't know if there is anyone out there who could write a script to search for patterns but my brain is failing to spot anything useful. |

Yours in the only Red Hat machine I have looked at so a lack of data there. The CentOS Linux 8 machines should be the same as mine... Of course, there may not be (m)any of those either. Red Hat must be paid for, bur IIRC, CentOS is free,. |

I notice my machine completed about dozen hadcm3s work units in March and April successfully. |

So far seg faults make up about 25% of the failures, while with the hadam4h, they usually make up <5%. |

Could this excerpt from the Boinc Manager Event log be any use? Itis from one of my failed tasks. They all seem to look like this.

Jean-David, That's just the listing of files that should have been produced if it had run to the end. These used to be written to stderr.txt which is what is displayed on the task webpages when they finish, but now are just listed in the message log at the end of failures when one or more files that should have been produced in a successful run, wasn't. |

So far, error types are missing libraries, seg fault, process creation error (computers with this seem to be crashing everything as they do with missing libraries) and bad cpu type error (all on machines running Darwin. As to spotting any pattern, nothing has emerged from the noise yet. You guys have my sympathy. I looked at all 6 of the tasks I tried to run that failed to see if others had trouble too. IIRC, Some had trouble. Some have not been retried. Two had missing 32-bit libraries They had a variety of operating systems. Even FreeBSD One failed with this; I have no idea how this happened. Process creation (../../projects/climateprediction.net/hadcm3s_8.36_i686-pc-linux-gnu) failed: Error -1, errno=2 execv: No such file or directory |
