Linda implemented TupleSpace for parallel and distributed computing. Linda (and TupleSpace) was an invention of the YaleLindaGroup led by DavidGelernter.
A commercial implementation is available from ScientificComputingAssociates?: http://www.sca.com/site/products/linda.html
They should not be confused with the other Scientific Computing Associates at http://www.scausa.com.
See: Sun's JavaSpaces and IBM's TSpaces (http://www.almaden.ibm.com/cs/TSpaces/)
Is TSpaces really related to Linda? It's hard to see from the IBM commercial overtalk.
