I’m running GPUGrid & Milkyway on an E4600 Core2Due with a 9600GT (XPPro) and Boinc 6.45 Multi CPU is set to 100% using both cores I observed that v 6.55 cuda status shows: Running (0.04CPU’s, 1 Cuda) Win task man shows that acemd6.55 runs between 40 – 46% CPU and 45-50% milkyway. Boinc 6.45 runs only 1 x Milkyway (Priority Low) & 1 x GRUGRID (Priority BelowNormal) with the above CPU usage The other cuda versions of Boinc (6.3.21 – 6.4.1 & 6.5.0) run 3 apps: 2 x Milkyway & 1 GPUGRID Milkyway uses 50% + 50% (Priority BelowNormal) GPUGRID only 0 – 1% (Priority Normal). GPUGRID task runs very slowly because Milkyway uses all CPU. Only when I manually change the priority for GPUGRID to High or Real-time it then uses 4 -5 % like it should This works fine using 100% of the PC but every time a new work unit starts the priority change back to normal. Any suggestions how can I force acemd_6.55_wini86 to automatically run a higher priority |

Use Process Lasso (free for home use) Downloaded & installed program GPUGRID & Seti(cuda)exits with "Computation Error" when I used Process Lasso to set the priority to "High" in the config. Only after I disabled Lasso the apps run OK again |

Sorry to hear that; works ok for me (High priority for acem... CUDA) cpu 3-5% on Q6600@3.3Ghz same for me at VISTA 64 |

Ubuntu 8.10 with 4 Gb, 6.4.5 and good drivers noticed acemd was using 2.3 Gb RAM at 70% WU progress, with BM showing "waiting for memory..." However, standard setting for BOINC preferences limits RAM usage to 50%. Changed this to 90% all the time. BM now shows "Running (0.04 CPUs, 1 CUDA)#. Not sure what the effect on the total runtime could be, but it is probably worth to recommend verifying RAM usage. Kind regards Alain |

This was about WU 129474 that succesfully finished overnight in 19807s on a GTX260. My next WU is now over 90% and acemd.. now only uses 22 MB!? Still on CUDA driver 178. Alain |
