I might have not completely understood your proposal but it seems to
me that those mini-threads do not solve the issue. In the Cell
architecture, the SPU are *independent* processors. They access the
main memory through DMA like operations and do not have cache. In
other words, for you mini-threads to work on the SPU, you need to fit
the mini-thread s' data, code and environment (e.g. GC) in 256 KB of
memory. As Xavier said, it seems quite difficult if not impossible.

Yours,
david
