Colloq: Abstract: 
The scale of current and future high end systems, as well as the increasing system software and architecture complexity, brings a new set of challenges for application developers. In order to achieve high performance on peta-scale systems, application developers need a programming environment that can address and hide the issues of scale and complexity of high end systems. Users must be supported by intelligent compilers, automatic performance analysis tools, adaptive libraries, and scalable software. In this talk I will present the Cray programming environment features that are being developed and deployed to improve user’s productivity on Cray Supercomputers. I will also discuss some of the challenges and open research problems that need to be addressed to build the system software for peta-scale systems.
