Sequoia is a programming language that is designed to facilitate the development of memory hierarchy aware parallel programs that remain portable across modern machines with different memory hierarchy configurations. Sequoia abstractly exposes hierarchical memory in the programming model and provides language mechanisms to describe communication vertically through the machine and to localize computation to particular memory locations within the machine.
A complete Sequoia programming system has been implemented, including a compiler and runtime systems for both Cell processors and distributed memory clusters, that delivers efficient performance running Sequoia programs on both of these platforms. An alpha version of this programming system will soon be made public.
The first draft of Sequoia's documentation  is now available online, along with some example programs .
