    Abstract

    Due to inherent non-scalability of superscalar processors, processor manufacturers have switched to mul-ti-core or chip multiprocessor (CMP) engines utilizing the symmetrical multiprocessing (SMP) para-digm. Since it is expected that the number of cores per chip will fast increase to a level in which only a fraction of the total computational power can be allocated for a single computational task using SMP, better architectures and computing models with easy-to-use (parallel) programming languages and tools are required. In this presentation we will outline a scalable general purpose CMP architecture being de-veloped at VTT that allows a programmer to utilize fine-grained parallelism under a strong model of computing and to allocate the full computational power of the CMP to arbitrary workloads ranging from a single computational task to multiple independent parallel programs. We will focus on performance is-sues related on latest architectural additions including step cache-based support for concurrect read con-current write (CRCW) access and fast multioperations. According to our preliminary evaluation, good performance figures and scalability can be achieved with these techniques in executing parallel programs written with a high-level language and compiled with very early prototype tools.
