ABSTRACT: In recent years, heterogeneous computing platforms "in a box" have quickly moved from being the exception to being the norm in high-performance computing (HPC). Examples of supercomputers that are based on such heterogeneous computing platforms now exist everywhere --- from the "AMD Opteron CPU + Cell Broadband Engine" heterogeneous combination found in LANL's Roadrunner (1.76 petaflops) to the myriad of emerging "CPU+GPU" heterogeneous combinations, such as in NSCS's Nebulae (1.27 petaflops). Another combination that is seeing increasing attention is the
This panel seeks to address arguably the three biggest problems in heterogeneous computing on the road to exascale: performance, power, and programmability.
