Sugar 2.0g x64 vs. Fried Shark 14110921 x64 - SF Clones One On One Rematch

The last encounter with Sugar 2.0f and Fried Shark 141107 was a lopsided win by Shark which maybe attributed to bad compile of Sugar 2.0f. This time, Sugar 2.0g version does better but still lost to Fried Shark 14110921 in the SF Clones One On One Rematch.

Here is the updated result:

Sugar 2.0f x64 vs. Fried Shark 14110921 x64 - 100R 1M1S

  1. Hi there
    Could you make a SSE 4.2 or some version for modern computers with your impressive Fried Shark ?
    Low end versions simply don't cut it.

    1. There is a post by Lucas Braesch in one of the releases that SSE4.2 is a misnomer. The equivalent compile is called "modern" which includes popcnt and prefetch. If the "sse4.2" option is used in the compile under MINGW, it does not run in my computer, so I refrain from doing it. In my test releases, I will just try to include a "modern" compile for those who demands the strongest.

      There is a "bmi2" option which is for the later Haswell computers but I don't do a compile because I have no way of testing whether it works or not.

    2. Hi
      Do the BMI2 compile please !
      I'm using a Haswell and will check it out and let you know.
      Also, please include Syzygy support if you can.
      Thank You

  2. I will provide bmi2 versions in my next tests but may not make a Syzygy version for personal preference. You may use the compiles of Marco Zerbinati like the Sugar and SFMZ series.

  3. OK, BMI2 is just fine, even if no Syzygy support.
    I'm really eager to try out a BMI2 version of you impressive Fried Shark !
    Thank you

  4. para cuando subiras tu version friedshark del la ultima stockfish del 12 de noviembre?

  5. Todavía estoy tratando de precisar la regresión que mostrar en mis pruebas y publicaré cuando el tiburón está correctamente frito.
