Because of my Messsage 64935... I have inter alia four AMD Radeon R9 Fury X VGA cards and it's still not possible to get work, if the project is 'stock'. I need to use (the following entries and apps are correct?) an app_info.xml file. [Windows 64Bit, (N-Body Sim. non-MultiThread (Single-Thread) CPU app)] <app_info> <app> <name>milkyway_nbody</name> <user_friendly_name>Milkyway N-Body Sim.</user_friendly_name> </app> <file_info> <name>milkyway_nbody_1.62_windows_x86_64.exe</name> <executable/> </file_info> <app_version> <app_name>milkyway_nbody</app_name> <version_num>162</version_num> <platform>windows_x86_64</platform> <file_ref> <file_name>milkyway_nbody_1.62_windows_x86_64.exe</file_name> <main_program/> </file_ref> </app_version> <app> <name>milkyway</name> <user_friendly_name>Milkyway</user_friendly_name> </app> <file_info> <name>milkyway_1.36_windows_x86_64.exe</name> <executable/> </file_info> <app_version> <app_name>milkyway</app_name> <version_num>136</version_num> <platform>windows_x86_64</platform> <file_ref> <file_name>milkyway_1.36_windows_x86_64.exe</file_name> <main_program/> </file_ref> </app_version> <app> <name>milkyway</name> </app> <file_info> <name>milkyway_1.36_windows_x86_64__opencl_ati_101.exe</name> <executable/> </file_info> <app_version> <app_name>milkyway</app_name> <version_num>136</version_num> <platform>windows_x86_64</platform> <avg_ncpus>1</avg_ncpus> <max_ncpus>1</max_ncpus> <plan_class>opencl_ati_101</plan_class> <cmdline></cmdline> <coproc> <type>ATI</type> <count>1</count> </coproc> <file_ref> <file_name>milkyway_1.36_windows_x86_64__opencl_ati_101.exe</file_name> <main_program/> </file_ref> </app_version> <app> <name>milkyway_separation__modified_fit</name> <user_friendly_name>Milkyway Sep.

Is the milkyway_separation__modified_fit part superfluous now, so I could delete this part in red (and this two apps)? - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - I made a forum search because of the project prefs point: Frequency (in Hz) that should try to complete individual work chunks. Higher numbers may run slower but will provide a more responsive system. Lower may be faster but more laggy. default 60 (corresponds to 60 fps) It looks like just the outdated Milkyway 1.20 ATI app used this settings. The currently Milkyway 1.36 ATI app don't use it. I set '1' (one) but the app use/show: Using a target frequency of 60.0 Is this OK, or a bug? - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - I'm a bit disappointed that a project task last ~ 16 seconds with the Milkyway 1.36 ATI app on one FuryX VGA card (1 WU/GPU). I looked to other PCs, e.g. hostid=590597 with 'R9 200 Series - Hawaii' VGA cards. This VGA card have just 44 ComputeUnits (CUs) A task last ~ 15 seconds. The/my FuryX have 64 CUs. But a task last ~ 16 seconds. Is there something wrong - possibilities to optimize/fine tune? Thanks. ![]() |

Take a look at memory speed and whether the R9 280 has 128bit, 256 bit or 384 bit thruput speeds, the faster the memory and the faster the bits get transferred at one time, the faster the card crunches. It's not JUST the CU's anymore. |

Don't you know that Fury X beats R9 290x memory bandwidth by 1.6 (512gb/s vs 320) |

I read a lot in the forum and found that the GPU apps can be fine tuned. I found:

It's not just memory speed here. Since MW use double precision calculations (DP) the card's DP compute capability is the real driver. R9 280 series DP = 1/4 SP R9 290 series DP = 1/8 SP R9 Fury X series DP = 1/16 SP The R9 280 series may not be the fastest single precision performer but the 1/4 DP to SP ratio makes it the leader in double precision for the $.

Hi Jojez J. Have a look there https://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=3987&postid=64975 Cheers |

I don't know if this ratios are correct... If I look online the 1.39 app say in the <stderr_txt>: (...) Estimated AMD GPU GFLOP/s: 672 SP GFLOP/s, 134 DP FLOP/s (...) This would be a 5:1 ratio for the R9 Fury X. ![]() |

Unfortunately this is expected with modern consumer cards. This project is all about double precision compute capability. The trend for both Nvidia and AMD over the last several years has been to significantly reduce the double precision compute capability on consumer/gaming cards in favor of single precision and other features. Wikipedia has good tables for comparing the stats across generation and model. My 6970 has more double precision compute than the fury x. My new card, the 7970, will have almost twice the double precision capability. https://en.wikipedia.org/wiki/AMD_Radeon_Rx_300_series https://en.wikipedia.org/wiki/Radeon_HD_7000_Series |
