The runtime works on all our supported platforms.

The runtime distribution includes the GASNet portable networking library--if you wish to download GASNet separately, you can get it from the GASNet website.

Our UPC-to-C translator is based on the Open64 open source compiler. Unfortunately, due to C++ portability issues the translator does not build on as many systems as our runtime.

If you cannot build the translator on your target architecture, you still have the option of using your own translator: just build it on a different, supported machine, and then have your runtime access it via either HTTP or SSH. This is mainly useful if you have a private subnet that is not connected to the Internet. Instructions for setting up HTTP/SSH access are in the runtime's INSTALL file.

The only system configurations that have been extensively tested for hosting the translator are:

Linux x86

Linux Itanium

Linux Opteron (32- or 64-bit)

Linux PowerPC (64-bit only)

Compaq/HP Tru64/Alpha

IBM AIX 5.2+ PowerPC (32-bit only)

Apple OS X 10.3+ PowerPC (32-bit only)

Apple OS X 10.4+ Intel x86

On all of these platforms, 'g++' version 3.4 or above was used. Success has been reported using older versions of g++, but this is not regularly tested.

You must have GNU 'make' on your system, and depending on your version of 'yacc', you may also need GNU 'bison'.

Instructions on how to build the translator are contained in the README file in the top-level directory.

If you're simply curious in seeing how our source-to-source translation works, you can inspect the generated C code using the upcc -trans option, or try our Online UPC-to-C translation utility.
