People in Stanford's graphics lab are doing promising
work making the Cell easier to program.
They have been busy creating a programming language
called Sequoia that focuses on memory hierarchies. A
programmer defines a task that recursively decomposes
the input data until it reaches the bottom of the memory
hierarchy, where it runs an optimized kernel. The runtime
environment uses a specification of the memory hierarchy
for the generic PC cluster, Cell Blade Server, etc. In the
case of a cluster, the runtime is built on top of MPI. In the
case of a Cell Blade Server, the runtime manages task
overlays and asynchronous DMA transfers of the data.
They have a paper that explains it well and has some
And the public release of their compiler and runtime
system should be publically available soon. The site
does have some more documentation of Sequoia.
