摘要:We consider the problem of minimizing, for a dataflow graph of kernel calls, the overall number of operand data transfers, and thus, the accumulated transfer startup overhead, in heterogeneous systems with non-shared memory. Our approach analyzes the kernel-operand dependence gra...

摘要:XPDL is a modular, extensible platform description language for heterogeneous multicore systems and clusters. XPDL models provide metadata about hardware and installed system software that are relevant for adaptive static and dynamic optimizations of application programs and syst...

摘要:We demonstrate how static, energy-efficient, compiler-generated schedules for independent, parallelizable tasks on parallel machines can be improved by modeling idle power. We assume that the static power consumption of a core comprises a notable fraction of the core's total powe...

摘要:Many modern parallel computing systems are heterogeneous at their node level. Such nodes may comprise general purpose CPUs and accelerators (such as, GPU, or Intel Xeon Phi) that provide high performance with suitable energy-consumption characteristics. However, exploiting the av...

摘要:We present VectorPU, a C++ based programming framework providing high-level and efficient unified memory access on heterogeneous systems, in particular GPU-based systems. VectorPU consists of a light-weight runtime library providing a generic, "smart" data-container abstract...

摘要:Exploiting effectively massively parallel architectures is a major challenge that stream programming can help to face. We investigate the problem of generating energy-optimal code for a collection of streaming tasks that include parallelizable or moldable tasks on a generic manyc...

摘要:We discuss three complementary approaches that can provide both portability and an increased level of abstraction for the programming of heterogeneous multicore systems. Together, these approaches also support performance portability, as currently investigated in the EU FP7 proje...

摘要:In contrast to standard compilers, generating code for DSPs can afford spending considerable resources in time and space on optimizations. Generating efficient code for irregular architectures requires an integrated method that optimizes simultaneously for instruction selection, ...
