Abstract
We are developing a compiler and runtime support system called
PASSION: Parallel And Scalable Software for
Input-Output. PASSION provides software support for I/O
intensive out-of-core loosely synchronous problems. This paper gives
an overview of the PASSION Runtime Library and describes two of the
optimizations incorporated in it, namely Data Prefetching and Data
Sieving. Performance improvements provided by these optimizations
on the Intel Touchstone Delta are discussed, together with an out-of-core
Median Filtering application.
