Dear Friends, The MCPlots project is currently completing an upgrade of its event generator codes and we plan to introduce this revised code into mcplots tasks for BOINC production very soon. From this point on, it will unfortunately not be possible to support 32bit environments and we plan to remove the 32bit option from the Theory application. To remind you, 32bit platforms are not officially supported by CERN for new installations of HEP codes since a few years already. So it has been more and more difficult to keep Theory compatible for 32bits even in "degraded" mode using only old versions of event generators. Currently the 32bit application contributes only 1-2% of total Theory computing power - see https://lhcathome.cern.ch/lhcathome/apps.php - so the phaseout will be practically invisible. Nevertheless this marks a milestone for the Theory project, and it’s time to thank again our early volunteers who have continued to support us with 32bit systems during the general move to 64bits. We recommend anyone who still runs on 32 bit systems to switch to Sixtrack which will support these for a while longer. Regards, Anton for the Theory team |

Good idea, is there a time when tasks be stopped for Theory(32bit)? |

It also looks like VirtualBox is dropping support for 32bit hosts. "Please also use version 5.2 if you still need support for 32-bit hosts, as this has been discontinued in 6.0. Version 5.2 will remain supported until July 2020."[/quote] |

https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=10447575 Sometime it's time to say goodbye. ;-) The performance in the x64 is much better. |

Today the new configuration without 32 bits support is subscribed for the production at BOINC. The 32 bits version of LHC@Home Theory application will be removed soon. Enjoy the progress of new configuration (revision 2362) at: http://mcplots-dev.cern.ch/production.php?view=control Thank you for your 32 bits contributions, and Happy New 64 bits Year! |

https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=10447575 Well you know I would like to run it as long as possible so I'll let it run any Sixtracks it can get (it still has the old GeForce 550Ti running Einstein GPU's) And you know I have a X64 disk to eventually update it so it will finally *see* that it has 8GB of the old DDR2 Ram instead of just 4GB I did that years ago on its twin pc so it runs the 8GB Ram (all 4 slots full) so it runs here and over at -dev but the GeForce 560Ti finally died so one of these days when it is not running for a few minutes I might have to plug in a 650Ti I have in my stash. (wish I could get some Theory tasks here right now since for some strange reason my satellite ip is running 10X faster than usual) |
