Version 2.0.2 of X10 is now available for download.  See the Release Notes for details on what is new in X10 2.0.2.  Included at the top-level of the X10 release is a directory of sample programs.


  • Source Distribution of X10 2.0.2 Use this if you want to build X10 yourself, modify the X10 implementation, or need X10 for a platform that is not one of the ones for which we provide pre-built binaries.


  • Download the X10 2.0.2 distribution for your platform.
  • Untar it.
  • See the INSTALL file in the X10 2.0.2 directory tree for additional instructions.

Binary builds of the Common PGAS runtime that match the X10 2.0.2 release are available as separate binary downloads. Under most circumstances, you should not need to manually download the Common PGAS runtime yourself. It is included in the binary X10 releases and will be automatically downloaded by the X10 build process if you are building from source.

This can be resolved by running as root:

echo `hostname` >> /etc/hosts
