Abstract : To achieve good I/O performance on irregular, loosely synchronous problems it is necessary to work both at the application and the system support level. The first section describes our effort at developing an efficient out-of-core parallel sparse cholesky solver as an example of an irregular, loosely synchronous application and the second section describes the Jovian parallel I/O library which provides support for collective I/O operations.
