Researchers from both academia and industry are invited to share their latest research findings in the area of EPIC architectures and compiler technology. The EPIC style of architecture was developed to enable new levels of instruction-level parallelism not achieved with traditional architectures. By allowing the compiler to express program parallelism and other relevant information directly to the processor, EPIC architectures can overcome hardware complexity issues that limit performance in traditional microprocessors. The major challenge in realizing the full potential of EPIC architectures is developing compiler and runtime optimization technologies that effectively deploy explicitly defined hardware mechanisms, and deliver performance for both commercial and scientific applications. This workshop will focus on promising research concepts that enable the EPIC architecture model. |
