CLAMH Introduction
April 2021

The Cross-Language Microbenchmark Harness (CLAMH) provides a unique environment for running software benchmarks. It is unique in that it allows comparison across different platforms and across different languages. For example, it allows the comparison of clang, gcc, llvm, and GraalVM Sulong on the same benchmark, and can also be used to compare the Java counterparts of the same benchmark running on any JVM. CLAMH allows users to verify vendor benchmark performance claims, baseline benchmark performance in their own compute environment, compare with other compute environments, and, by so doing, identify areas where performance can be improved. CLAMH has been released Open Source in the GraalVM repository -
