Hi, Please give it a try, http://www.cct.lsu.edu/~jtao/cct/xirel/einsteintoolkit/BENCHMARKS.tgz BENCHMARK should be under your Cactus directory. After you cd BENCHMARK, run ./xirelbench.sh To avoid any errors, you must have the whole set of einsteintoolkit downloaded and simfactory correctly configured. Regards, Jian
