       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
       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?
