Abstract
In this document we make a brief review of memory management and DMA considerations in case of common SCI hardware and the
Virtual Interface Architecture. On this basis we expose our ideas for an improved memory management of a hardware combining
the positive characteristics of both basic technologies in order to get one completely new design rather than simply adding
one to the other. The described memory management concept provides the opportunity of a real zero-copy transfer for Send-Receive
operations by keeping full flexibility and efficiency of a nodes’ local memory management system. From the resulting hardware
we expect a very good system throughput for message passing applications even if they are using a wide range of message sizes.
