SPEC Releases Free SPECjvm2008 Benchmark
The Standard Performance Evaluation Corp. (SPEC) has released SPECjvm2008, a new Java virtual machine benchmark with multithreaded workloads that represent a broad range of application areas. SPECjvm2008 is available for free downloading on the SPEC website: www.spec.org/jvm2008/.
The new benchmark, which replaces SPECjvm98, enables performance comparisons for systems running the Java Runtime Environment (JRE). Metrics are influenced by the performance of the just-in-time (JIT) compiler, memory management, and other aspects of the system, including the processor, cache and memory bus.
New evaluation tools in SPECjvm2008 include a plug-in analysis framework that gathers information on factors such as heap usage during testing, and a reporter that displays a summary graph of all test runs. CPU2000, since new benchmarks have been added and existing ones changed.
SPECjvm2008 allows testing under both base and peak rules. Base testing simulates environments in which users do not tune systems for increased performance. Peak results show how tuning can be used to drive maximum Java throughput. Anyone submitting a peak result for publication on the SPEC web site must also submit a base result.
SPEC members participating in the development of SPECjvm2008 include AMD, BEA, HP, IBM, Intel and Sun.
SPEC expects that the free software will be valuable to four key groups within the IT community:
- IT managers looking to improve JVM performance for specific applications.
- Researchers who investigate new algorithms for garbage collection or code generation.
- Engineers who create and enhance JVM products and conduct performance testing.
- Marketers who want to call attention to JVM performance of new products.
