+To use hpvm to compile benchmarks set environment variable `LLVM_SRC_ROOT` to llvm directory in your local repository
+```shell
+export LLVM_SRC_ROOT=<full path to hpvm>/llvm
+```
+
+### Benchmark Suites
+
+Benchmark suites have been migrated to the LLVM 4.0 build. They are located
+in [VISC](/llvm/test/VISC/parboil/benchmarks).

+### Running an example (sgemm in parboil)
+```shell
+cd llvm/test/VISC/parboil/benchmarks/sgemm
