ABSTRACT:
X10 is a modern object-oriented programming language specifically designed to support productive programming of large-scale, high-performance parallel applications. X10 is a realization of the Asynchronous PGAS (Partitioned Global Address Space) programming model in a Java-like language. In this talk I will introduce the APGAS programming model and describe the key languages features of X10 (finish, async, at, Places) that support it. I will summarize the current implementation status of X10 and our experience in running X10 programs on petascale HPC systems. I will also discuss some of our current research and future plans for extending and enhancing X10 in support of exascale computing.
