Free Software Linux

The Chiphipper program is an interesting program where IBM gives its ISV partners access to a toolset that allowed them to validate their x86 Linux applications for Linux on POWER and z mainframe platforms. It may seem trivial, but ask any developer and the challenge of moving from one architecture to another without tools can be a pain. With Chiphopper, the process becomes fairly automated in discovering what needs changed before starting a port and makes it fairly easy to offer an application on multiple platforms. Developers use these tools on their x86 code so you don’t even need access to Power or mainframe hardware to use them.  You can even use the tools with open source applications.

Internally within IBM we get to see a number of great adoption statistics for technologies and IBM products. One that has been increasing over time is the usage of Linux virtualized on Power Systems (e.g. POWER6 processor based servers). These systems were always considered “UNIX servers” and that was true in the old days. Today, with virtualization, how do you count a system that has 30% of its capacity dedicated to Linux partitions and 70% to AIX? How about 90% Linux, 10% AIX?  The same trend for adoption of Linux on scalable systems is true for Mainframes as well. These systems offer customers a significant amount of flexibility to match workloads and applications to the best hardware without disrupting the OS, tools, etc.
