Optimization manuals updated
Author: Agner Fog Date: 2009-09-27 11:24
My optimization manuals have now been updated.

I have included tests of the Intel Core i7 processor and the lightweight processors Intel Atom and VIA Nano. Furthermore, there are many small additions to all five manuals

Thank you Doktor Agner. I always follow you advice. Your manuals great for new to medium level programmr such as me. And some topics most important stuff like unions, enums, cpu dispatcing.


But i want to more cover on dynamic cache allocation( on msvc++ libs _alloca function ) and cache splits problem. Many software developers unable to cope with cache splitting.

Thanks. Good day.

You are right that cache use is difficult to optimize.
The _alloca method is described in chapter 8.6 "Dynamic memory allocation" of my C++ manual. I can recommend this method where it is possible. I have made some examples of container classes that use contiguous memory in order to optimize cache use. You can find them in www.agner.org/optimize/cppexamples.zip. These container classes are useful as an alternative to the standard template library (STL).

Hi,
Killer! thanks for the updates! those have been a refrenece for me for years.
can't think of an addition, dont have the enough expertise to suggest any frankly

p.s.: considering any "GPU" guide any time soon?

A GPU guide would be very useful since people are putting more and more work into graphics processing units (GPUs) instead of CPUs - even non-graphic calculations. However, I am not going to make a GPU guide. Somebody else will have to do that.

Hi Doctor Agner,

I've been reading your excellent optimization manuals for years, but I've just discovered your blog. I have a small request; every time you publish a new version of your manuals, I eagerly download them for reading, but it is hard to know what is new in every release: could you publish a small changelog in every manual so that one can directly go to new or changed sections?

Thanks,

-Giovanni Deretta

Several people have asked for this. However, a revision log would be very long because there are lots of small changes, such as a typo fixed, a number added to a table, adding small details, etc.

It might be possible to compare the files and track changes using Compare Suite but I have not tried it.

The most important additions in the latest version are:

  • New processors tested: VIA Nano, Intel Atom, Intel Core i7
  • More details about the forthcoming AVX instruction set
  • Discussion of hyperthreading
  • Metaprogramming

A new generation of the VIA Nano processor is going to be released soon. I have tested a prerelease sample of a VIA Nano L3050. The results are in my microarchitecture manual and in the instruction tables.

The chapter on CPU dispatching in the C++ manual has been rewritten and expanded.

There are minor changes in the other manuals.

The updated manuals are, as always, at www.agner.org/optimize/#manuals
