  2. Back End Compiler Panel – WHY? • Focusing on the code generation aspects of advanced high performance computing compilers • Interested in how the generated code can work with run time support to adapt across the spectrum of architectures • Like to understand how unchanged applications can run optimally on powerful vector processors as well as cluster based machines with high counts of relatively low performance processors • Not concentrating on compiler language characteristics, although there may be some specific directives that come to light as enablers • Interested in exploring a way to provide higher levels of productivity for application writers • The multi-core direction has the potential to make the next generation of computers significantly harder to program than anything we've seen to date

  3. Back End Compiler Panel Questions • 1) Are compiler code generation techniques going to transition along with the hardware transition from multi-core to many-core and hybrid systems and at what speed? • 2) What information do you need from a Compiler Intermediate Format to efficiently utilize multi-core, many-core and hybrid systems that is not available from traditional languages like C, C++, or F90? Are you looking at directive-based or library-based approaches or is there another approach that you like? • 3) Is embedded global memory addressing (like Co-Array Fortran) to be widely available and supported even on distributed memory systems? • 4) What kind of hybrid systems or processor extensions are going to be supported by your compiler's code generation suite? • 5) What new run-time libraries will be available to utilize multi-core, many-core, and hybrid systems and will they work seamlessly through dynamic linking?
