class dacapo(test.test):
This autotest module runs the dacapo benchmark suite.
This benchmark suite is intended as a tool for Java benchmarking by the
programming language, memory management and computer architecture
communities. It consists of a set of open source, real world applications
with non-trivial memory loads. The suite is the culmination of over five
years work at eight institutions, as part of the DaCapo research project,
which was funded by a National Science Foundation ITR Grant, CCR-0085792.
