摘要：

We describe recent development work on the core-collapse supernova code CHIMERA. CHIMERA has consumed more than 100 million cpu-hours on Oak Ridge Leadership Computing Facility (OLCF) platforms in the past 3 years, ranking it among the most important applications at the OLCF (1). Most of the work described has been focused on exploiting the multicore nature of the current platform (Jaguar) via, e. g., multithreading using OpenMP. In addition, we have begun a major effort to marshal the computational power of GPUs with CHIMERA. The impending upgrade of Jaguar to Titan - a 20+ PF machine with an NVIDIA GPU on many nodes - makes this work essential.
