Hello all, If I want to modify the limitation of jobs per PCPUs in the source code, where should I do this? Regards. |

Hello all, You can set it in config.xml <max_wus_to_send> x </max_wus_to_send> |

Hello all, Thanks my friend,but I want to fetch more jobs per PCPUs now I have two Cores and the boinc has fetched only two WUs simultaneously. |

Use the <ncpus>N</ncpus> option in cc_config.xml This emulates that you have more cores than you actually have. A value of <ncpus>4</ncpus> will run 4 tasks at a time, even on a 2 core CPU. See http://boinc.berkeley.edu/wiki/Client_configuration for more information about the cc_config.xml file and its options and flags. |

Use the <ncpus>N</ncpus> option in cc_config.xml thanks, and I have read somewhere that there is a configuration that how much each task can used CPU time as I think,Is that true? for example if I want to adjust that each job utilize only 50% of each CPU time how can I do that? And one more thing, Is it possible to set the ncpu at the run time? |

thanks, and I have read somewhere that there is a configuration that how much each task can used CPU time as I think,Is that true? for example if I want to adjust that each job utilize only 50% of each CPU time how can I do that? Set it through a project's account->computing preferences->CPU time, or edit global_prefs.xml, value <cpu_usage_limit/> And one more thing, Is it possible to set the ncpu at the run time? When using <ncpus/> you need to exit & restart BOINC for it to use this value, so it's always used at the start of run time. Apropos, see this thread for a discussion on what's used best, global_prefs.xml or global_prefs_override.xml |
