X10 won the HPC Challenge "Best Performance" Award in the Class II competition at SC'12. The X10 submission (paper, presentation, code) was based on X10 code for Global HPL, Global Random Access and Global FFT and Unbalanced Tree Search (UTS) benchmarks and performance runs on the PERCS machine. All benchmarks were run at 32K cores, some also at 55K cores. We showed good scaling and good to outstanding absolute performance on all benchmarks. More details are available at the HPC Challenge 2012 Awards page.
We're very happy to announce that X10 and X10DT 2.3.0 are now available for download! This is a major release of X10 and includes significant enhancements to X10/Java interoperability. To download the release, please see the X10 Release 2.3.0 page.
The ScaleGraph project has made an initial open source release of ScaleGraph version 1.0. ScaleGraph is an X10 library that provides support for both managing and analyzing large graphs in a scalable fashion. More details are available at ScaleGraph.org and in an X10'12 workshop paper by the ScaleGraph team.
