Is someone interested in experimenting with a app that uses the AMD fma4 instruction set ? FWIW, i've been running it for a couple of weeks now at it works (valid results). If someone is interested i could upload it. Let me know. Join BOINC United now! |

Is someone interested in experimenting with a app that uses the AMD fma4 instruction set ? AAAH - noob alert! ;) currently i got no AMD-FX at hand, but would you throw in some performance-numbers? |

I wish i could throw in some numbers but unfortuantely, my cooling is not efficient enought.. (meaning my fx6100 keeps throttling down to 1.4 GHz)... So it's a guessing game. So, the only available option is testing it on some bullozers that can handle the heat ;) Join BOINC United now! |

Is someone interested in experimenting with a app that uses the AMD fma4 instruction set ? Did you recode the app or change compiler settings only? I have FMA2 app and not difference between AVX and FMA2. |

Is there any speedup over avx? AVX was always slower than the sse2 or sse3 app. Not even using the intel compiler could fix that. So i've switched to gcc 4.8.2 and recoded the parts of the app that could make use of amds fma4. The real question is, if the app is faster than the sse2 one (fastest of them all), however , as i've mentioned earlier, my cooling sucks and my fx 6100 keeps trottling so there's no way of me telling what the differece is.

Hi, I've added my A10-7700 https://asteroidsathome.net/boinc//show_host_detail.php?hostid=88982 which is fma able. Unfortunately BOINC does not say fma4, but since it is a brand new device I suggest it is. One info is still missing; your application, is it for Windows or Linux? If Windows is good I would be glad to test it! Alexander |

Last modified: 8 May 2014, 1:25:45 UTC The link is this: http://asteroidsathome.net/boinc/show_host_detail.php?hostid=88984 Yes, your AMD A10-7700K have FMA3 and FMA4 http://www.cpu-world.com/CPUs/Bulldozer/AMD-A10-Series%20A10-7700K.html Maximum operating temperature 72.4°C You can use TThrottle to control the temperature. You can also use SIV - System Information Viewer to find CPU Features for certain: http://rh-software.com/ http://rh-software.com/downloads/siv.zip Click on the right-bottom the button that say [MMX+ .....] - ALF - "Find out what you don't do well ..... then don't do it!" :) |

Last modified: 9 May 2014, 19:05:17 UTC I have tested the app but only ran 4 tasks with it. http://asteroidsathome.net/boinc/results.php?hostid=13438&offset=0&show_names=0&state=4&appid= Against an i7-4770, my A8-6500 3.5GHZ took 10,996.37 CPU time vs 9,167.34 CPU time on the i7. Against an i7-3770, mine took 9,752.09 CPU time vs 7,808.02 CPU time on the i7. Against an i5-4570, mine took 10,705.40 CPU time vs 7,551.07 CPU time on the i5. The other task was ran against a GPU. So, they take longer but the i7's and i5 have much larger Floating Point and Integer figures than mine. I don't even know what clock they are running. My A8-6500: Measured floating point speed 1523.05 million ops/sec Measured integer speed 6243.76 million ops/sec i5-4570: Measured floating point speed 3496.34 million ops/sec Measured integer speed 14860.04 million ops/sec i7-3770: Measured floating point speed 3688.48 million ops/sec Measured integer speed 13060.77 million ops/sec i7-4770: Measured floating point speed 3563.17 million ops/sec Measured integer speed 14800.09 million ops/sec I think this needs more testing. Hope the project scientists are interested in testing this. |

It is for Windows. I only have one A8-6500. I've sent a PM to Cruncher, let's wait for the answer. |
