Is this project designed for integer or floating point calculations? I ask this because: 1. I use R@H to burn in new servers 2. I use R@H to keep idle or old servers busy In the process I am starting to find that I can use R@H to benchmark my machines instead of using that electricity on synthetic tests that provide no value to anyone but my organization. All that being said I just want to know if I should consider this more of a Int or FP benchmark so I can better compare it to my production tasks. |

The purest integer project that I know of is Prime Grid. As far as I know all the rest are mixes. Were I to guess I would suggest that at best RaH is 60/40 FP/Int ... To go more to FP heavy you should opt for a project like Einstein or Milky Way. {edit-add} One advantage to MW is that the code has been published so you can do your own count/estimate ... same with SaH though I think their code is longer ... |

That's interesting. Based on some of the comparative numbers I am seeing between the CPU benchmark numbers and the actual work completed I was guessing it was more integer focused, 70%I/30%FP I was going to guess. Anyone else have a hypothesis? |
