I've read that while you process more WUs in linux, you get less points for them. In the end, you actually get less points overall while contributing more. Seems really silly.
Also, thanks guys. |

Really, twiddle... opinions, including mine can and will substantially differ. My FAHV fetch 60-100% more per computing hour [since tasks are variable length, a 'per-task' grant comparison is quite incorrect]. This higher hourly credit is concomitant to the higher speed on Linux for FAHV [all VINA sciences] of 65-70%. CEP2 definitely rewards richer, compensating for the lesser efficiency, by about 5-10% greater Elapsed-CPU time gap on Linux, which hopefully improves when the CEP2v2 app, better Q-Chem, goes to production... next year is me feel].
(Now how did we get onto the bleeding credits again  ... the issue 'lives' , knreed  ) |

That's not what I see on my end. I've seen approximately a 30-40% decrease in WU run time, depending on the project. Which means I'm cranking through more WU's and getting more points per hour, again depending on the project(Again, depending on what percentage of certain projects I"m crunching, I see an increase in points per rig of around 30-45%).. This held true even for the HCC GPU WU's on my Linux box using a piddly HD6670. Average run time went from 18+ minutes per WU down to 11 minutes per WU. So yeah, that bit about Linux is horse hockey, to paraphrase Colonel Sherman T. Potter.  |

From that, you do indeed do far more work units, like I said, but you get less points for them - So much so that you actually end up getting more total points in windows. At least when it comes to HCC. I'll probably still run linux because I hate inefficiency, which is also why it's annoying the WCG source code isn't available to optimize. |

The code you are running for the research is not WCG code. It is the code of the researchers. Cheers

WCG will -Never- allow programs to be optimized by users, which would simply introduce another vector to make quorums fail [have we not that very issue now?]... understand this is searching for cures, not primes or aliens.

Looking to build a crunching machine - Workhorse?
----------------------------------------Here's my approach:
Define requirements (max output, GPU? etc) Research options for components (no reference to costs at this point) Shortlist components keep to 2 or 3 of each type MB, CPU, RAM etc (still no reference to costs) Thin out short list to 2 options Select best set of components based on suitability to meet requirements within budget constraints order selected components Build when they arrive! The other option is to forget the budget and by the best (or close to) available at the time, without breaking the bank or credit card! lol BTW - I usually start with the former approach and end up with the latter!
Mamajuanauk is the Name! Crunching is the Game!
