Can HPcc Give High Performance if applied to each node of a parallel computer?
YES! If one uses the same separation between control and data transfer explained for metacomputing case
Build a “bridge” that accepts MPI HTTP or CORBA invocation but invokes either the powerful slow CORBA mechanism or the nifty optimized MPI
Why address nodes as CORBA? -- so you can build applications uniformly so they can access nodes and servers around the world in same message passing style
Why address nodes with MPI? -- so you can get code that executes very fast!
Why address nodes with HTTP? -- so you can get advantages of CORBA today as Web Servers dominate!
