This portion of the X10 svn repository contains various benchmark programs written in X10. Our active benchmark development is currently mostly happening in the PERCS subdirectory. This includes the codes used for the X10 2012 HPCC submission. Please look in PERCS first for the latest versions of high performance X10 code. The OBSOLETE portion of the repository contains X10 benchmark programs that are not being actively maintained. Typically these programs are written in X10 2.1 or X10 2.2. The VERY_OLD portion of the repository contains benchmark programs written in very old versions of X10 (eg pre X10 2.0) that would take significant work to port forward to X10 2.3. All of the other top level directories contain benchmarks that should work with the current version of X10. If you find some program that is not under OBSOLETE or VERY_OLD doesn't work, then please let us know by opening a JIRA: http://jira.codehaus.org/browse/XTENLANG. We would be very happy to accept contributions of additional benchmark programs (or ports of existing code in OBSOLETE or VERY_OLD to the current version of X10). If you want to undertake such an effort, please let us know so we can coordinate community efforts.
