IBM has launched a beta program for a new compiler for Linux on System z. If you’ve been working with IBM platforms you may already know the xlc compiler. This compiler is now also available as a beta for Linux on System z as well.
Interested customers and software vendors should register for it at this registration link (free IBM ID required).
The key difference to the gcc included in the distributions is that this compiler is independent of the distribution. So as a software developer you can use this compiler and more important the generated binaries on all the supported Linux distribution. By that you can get improvements like zEC12 exploitation earlier than waiting for the next gcc in a distribution.
And my personal hope is that the performance will also be good as well. We will know this when the compiler is generally available.
