Compiling Gurus: need advice

[Edsel Apostol]

Hi Ron,

Thanks.

I've grown accustomed already to Dev C++ but I will try Code Blocks for a change.

For PGO you must have the professional edition. There was also a professional edition 2008 Beta 2.

Hi Thomas,

Thanks for the tip. I will try to download that one. Do yuo have any idea when will they stop supporting downloads for these betas?

Anyway, I and most of the programmers out there are awaiting the release of the latest Toga. I am planning to add SMP to my engine and I hope that I can learn something from Toga implementation.

Hi Edsel,
i think you can´t download the beta anymore. But you can download a 90 day trial version:

In the case of a good SMP implementation you can´t learn from toga because my SMP implementation is only a simple shared hashtable. Use Glaurung 2 to learn how to implement a very good smp algorithm (YBWC). And Tord has implemented this algorithm really great. Fast and readable. the best what i have ever seen.

Yes, Thomas is right. You can also download trial professional versions of ICC compiler at Intel site. I guess you already know the other Microsoft SDK requirements for such compilers.

Just pm me dre, if you need some assistance. Remember, we live in the same archipelago

Scorpio's threading is also easy to understand.

[Edsel Apostol]

What SMP algorithm does Scorpio support? Is it efficient? It seems to be an iterative search instead of a recursive search.

[Dann Corbit]

From Search.cpp, line 630:
PARALLEL search=> YBWC

Real nice paper on parallel search:

Thanks Dann.

I will be waiting for the release of ZCT by Zach Wegner. He says he will release it after CCT and it has an iterative search with DTS support.

Is DTS the most efficient SMP algorithm? Based on what I read that is the algorithm used by Zappa and Chess64.
