Unix/Linux :
fedora 30 64 bit
(Message 62071)
Posted 3 Feb 2020 by nairb Post: An update on using fedora linux I finally grabbed some w/u’s. So I suspended them before they could start and did the following to try and find out which libs the climate app used. Here is the linux that I am using. Fedora 30 workstation, 64 bit uname -mr 5.4.12-100.fc30.x86_64 x86_64 The following is the output from ldd ldd hadam4_8.52_i686-pc-linux-gnu linux-gate.so.1 (0xf7efa000) libpthread.so.0 => /lib/libpthread.so.0 (0xf7ea7000) libdl.so.2 => /lib/libdl.so.2 (0xf7ea1000) libstdc++.so.6 => not found libm.so.6 => /lib/libm.so.6 (0xf7dcf000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xf7db1000) libc.so.6 => /lib/libc.so.6 (0xf7c0a000) /lib/ld-linux.so.2 (0xf7efb000) SO, it looked like the libstdc++.so.6 is missing. So I installed it And another way of finding (some?) of the libs (Part) of the output of readelf -d hadam4_8.52_i686-pc-linux-gnu 0x00000001 (NEEDED) Shared library: [libpthread.so.0] 0x00000001 (NEEDED) Shared library: [libdl.so.2] 0x00000001 (NEEDED) Shared library: [libstdc++.so.6] 0x00000001 (NEEDED) Shared library: [libm.so.6] 0x00000001 (NEEDED) Shared library: [libgcc_s.so.1] 0x00000001 (NEEDED) Shared library: [libc.so.6] It looked like I had all the libs installed (hopefully). I un-suspended one of the tasks And…. So far its done almost 1% without falling over. Its a simple and cheap upgrade to an I5 processor or even one of the I7 ones and a bit more ram. If this test with fedora works then a better desktop is the way forward. |

Posted 29 Jan 2020 by nairb Post: Has anybody tried using fedora 30 workstation for climate w/u. Its running on an intel i3 processor. Does the download of new w/u automatically select 64bit models or will I need to get some of those 32bit libs? Thats assuming there are some 64bit linux to be had. ta Nairb |

Posted 25 Apr 2019 by nairb Post: Well I have just grabbed 4 more w/u. 2 are safra/790. I checked their history to find they have both failed on other computers with "computing error". I'm not too keen to let them run for 3-4 days to have another "computing error". I would rather let the 2 sam50's have a go. Is it fair game to abort the safra ones??. |

Posted 21 Mar 2019 by nairb Post: I thought I would give it another go and have a safr50 791 & sam50 804 running for a whole 24 hrs and still not had a fit.(:Segment violation) they are at about 13%. I dont have that warm feeling of confidence. |

Posted 8 Mar 2019 by nairb Post: I was finding that the Intel I5 win10 laptop was having many, many wireless dropouts while doing the w/u. Now they have all died the machine seems to be fine again. A coincidence maybe. It was fine with other climate w/u. Once, back in the depths of time I had what was called a "farm" of some 55-60 computers doing several projects. Before the arrival of the mighty pentium4 and a pentium Pro was still good enough for seti work. Rising eleccy prices means I usually only use 1 laptop nowadays. With other machines joining in occasionally. I have not found many aliens yet. |

Posted 8 Mar 2019 by nairb Post: It seems that all 3 w/u have failed with :Segment violation. I have one left to do but may as well abort it. 3 out of 3 fail is not encouraging for the 4th w/u which is a 789 I think. |

Posted 8 Mar 2019 by nairb Post: [Nairb wrote]... My question is, are these models restartable. In other words if I get 25 days into a model and there is a power cut... One of the w/u has crashed with Signal 11 received: Segment violation. It did manage 3 days before having a fit. No restart during that time.... Wonder how the others will do!! Edit: 2nd one failed with "Signal 11 received: Segment violation"... maybe a memory issue?? |

Posted 4 Mar 2019 by nairb Post: Just managed to get 4 new tasks. They are the Wah2_safr50-... Its says they have a runtime of approx 30days. My question is, are these models restartable. In other words if I get 25 days into a model and there is a power cut... And I lose the 4 models its a waste of effort. ta Nairb |

Posted 22 Jan 2019 by nairb Post: Yup, I had 5 of these drop thru. So just it case I have suspended 4 of them and the one thats running is 16hr and still OK. But then the 781's ran fine almost to completion. RIP 871's |

Error while computing???
(Message 59473)
Posted 20 Jan 2019 by nairb Post: Well its not a huge success.... I have completed 2 w/u since rejoining. Both have crashed with Model crashed: REPLANCA: PP HEADERS ON ANCILLARY FILE DO NOT MATCH Both at the end of their runs.. a total of 10.5 days of processing/science wasted. Not a big deal in the world of climate prediction but not very encouraging to get more work. Time to wander off for a while I think. |

(Message 59386)
Posted 10 Jan 2019 by nairb Post: Thanks for the info. So the zip files are the science bit. So if a w/u fails at some point and the zip files are still waiting to get uploaded then the science is lost also?. Are partial completed w/u still of value to the project?. Its frustrating seeing 5 days of processing going to waste.... I will give it another go when the zip upload issues go away. |

(Message 59379)
Posted 10 Jan 2019 by nairb Post: The w/u ran to 100% and then gave "computing error" with msg of Model crashed: REPLANCA: PP HEADERS ON ANCILLARY FILE DO NOT MATCH The job had 7 trickles waiting to upload.... when it reported the end of job the trickles were aborted (They disappeared anyway). So I guess its a loss all round. I dont seem to do to well with Climate w/u with almost a 50% fail rate. |
