When it comes to the compiler the general expectation is to kick off a compile job and get the executable fast that is functional and is highly tuned for the target hardware. Like any other tool, compilers can be tuned to suit the application. That's where this session is going to help.
In this session we answer some of the most common questions asked when using compilers, such as: What does ARCH(n)/TUNE(n) do for/to my compiled code? What can HGPR, FLOAT( AFP ), COMPACT do to improve the code generated by the compiler? What coding techniques can benefit from higher arch levels? What happens to my code when I turn optimization on? What optimization level can get me the sweet spot between compile time and run time performance? What other options can affect application performance?
This session contains new content beyond what was presented in San Francisco.
