MP-MPICH differs from the current MPICH in the following aspects.
It is a single source tree which compiles under Unix and Windows NT and includes special communication devices and a remote-execution tool for Windows NT.
MP-MPICH is a superset of SCI-MPICH which allows inter-process communication directly via a fast SCI-interconnect. This results in message latencies of less than 7 us between distinct nodes. SCI-MPICH is usable with PCI-SCI-adapters of Dolphin.
