✦ Synopsis

HDF is a library and file format for storing and exchanging scientific data. In the absence of a Java (TM) implementation of the HDF library, Java applications that need to directly access data in HDF files require a Java interface to the native code HDF library. This document describes the design of the Java interface for the HDF library and one prototype applicationthe Java HDF Viewer (JHV).

Performance issues discussed in this paper appear to be inevitable consequences of the technologies that provide the portability and security of Java. The performance penalties are not significant for many applications, but become very significant for data-intensive computing. Just-in-time compiler technology will probably have little impact on the data copying and memory management issues described in this paper.
