- If you need more than 4 links per node in your hypercube, you can use
- more than a single transputer per node. E.g., two transputers connected
- by one link have 6 links free, so allow for a 64 node hypercube consisting
- of 128 transputers.
-
- The 93.1 release of our PACT Parallel C compiler features virtual
- channels, removing the logical restriction of 4 outgoing (and incoming)
- channels per processor. With virtual channels, arbitrary logical networks
- can be implemented on arbitrary hardware, with multiplexer and router
- processes automatically inserted where necessary to allow any task to
- connect to any other task in the entire system. The upcoming T9000
- provides hardware support for this, of course.
