Profile Guided Optimization, or PGO, is an approach to optimization where the compiler uses profile information to make better optimization decisions for the program. Profiling is the process of gathering information of how the program is used during runtime. In a nutshell, PGO is optimizations based on user scenarios whereas static optimizations rely on the source file structure. VC++ has supported this approach to measurement-based code optimization since VC2005. In this episode of GoingNative, we are going to dig into VC++'s implementation of PGO with some of the folks who make it: Program Manager Amit Mohindra and Development Lead Ten Tzen. Tune in.

[00:00] GoingNative();\\ Charles and Ale discuss C++ at Build 2012 and introduce Profile Guided Optimization.
[04:09] Charles interviews VC++ back end compiler team members Ten Tzen (lead developer) and Amit Mohindra (PM) about VC++'s implementation of PGO. Whiteboarding included. This is a long interview, so make some time.
[01:04:15] ~GoingNative(); // Charles and Ale reflect on PGO, Charles answers Herb Sutter's question (that Herb asked Charles during his Build 2012 C++ session (in his intro remarks). Hi Herb!
