[New release] BRP app v1.23/1.24 (OpenCL) feedback thread
(Message 112079)
Posted 13 May 2012 by terencewee* Post: First WU awaiting validation. Second WU completed & validated against a CUDA device. Good job! Processing third WU - no square dots on screen. Memory usage back to 369MB(dedicated), ~38MB(dynamic). Looks like there may be a problem with initial run. Scenario 1: Reboot > BOINC > run WU. Square dots on screen, no driver restart. Consecutive WU ran fine, with no square dots on screen, no driver restart. Scenario 2: Reboot > runs some apps > BOINC > run WU. Will report back tomorrow. |

[New release] BRP app v1.23/1.24 (OpenCL) feedback thread
(Message 112077)
Posted 13 May 2012 by terencewee* Post: v1.24 The app still corrupts the screen with square dots during the initial start-up. But there is not driver restart. Memory usage is 369MB(dedicated), ~39MB(dynamic). Seems faster. Will be running consecutive WUs this round using this host. 1st result reported. 2nd WU ran fine without any square dots on screen. Memory usage is higher. 475MB(dedicated), ~38MB(dynamic). |

Posted 1 May 2012 by terencewee* Post: Using this host. It's a mobile workstation, i7-820qm, FirePro Mobility 7820 (Juniper-based). Driver Package: 8.911.3.3-120309a-136336C Catalyst version: 11.11 I was running POEM++ OpenCL x3 WU on it. Pause all running WU. Exit BOINC. Re-launch BOINC. Select Albert WU. Resume @ ~0.018%, the screen starts to have multi-color square dots But it continue running. Pause Albert WU. Move mouse/window, dots disappear. Resume Albert WU. Driver restarts/recover @ ~0.320%. Pause Albert WU. Exit BOINC Restart machine. Login, launch BOINC. Resume Albert WU. No dots, continue run to completion (I hope). Hope this can be rectified before release. clinfo dump: Number of platforms: 1 Platform Profile: FULL_PROFILE Platform Version: OpenCL 1.1 AMD-APP (831.4) Platform Name: AMD Accelerated Parallel Processing Platform Vendor: Advanced Micro Devices, Inc.

Posted 11 Feb 2012 by terencewee* Post: @Mikie: Something to check to get BRP-OpenCL working for you: 0] Select all A@H tasks, suspend them. 1] Stop BOINC & don't run anything else 2] Check your environment variable TEMP (TMP), clean up that folder (sort by date, delete old files, etc.) 3] CHKDSK your HDD 4] Turn off Aero 5] Restart and run BOINC 6] Click on an A@H task that wasn't running previously, resume it (to ensure it's a fresh slot) I'm running Cat-12.1, 5850 (standard, 1GB), Win7-64, a free core dedicated to A@H running task. Hope it's working for you. -- terencewee* Sicituradastra. |

Posted 10 Feb 2012 by terencewee* Post: http://albert.phys.uwm.edu/results.php?userid=333612 All WUs validated. v1.19 and v1.20 - running on 5850 (Cypress) and M7820 (Juniper). Will continue test run again when finished with POEM++ OpenCL WUs. Good job! |
