About

This repo compile SPECCPU2006 (mostly) in parallel. This repo depends on official spec tools to preprocess Fortran files.

The global optimization flags are set in the root Makefile and Makefile.apps. The compatibility flags and including paths are set in each Makefile of benchmarks.

How to

• set SPEC2006 path in env vars

export SPEC=/spec2006_path

• source shrc

pushd $SPEC && source shrc && popd

• set SPEC_LITE env var to the path of this repo

export SPEC_LITE=$(pwd)

• copy source

bash scripts/src_copy.sh

• compile binarys

make ARCH=riscv64 \
     CROSS_COMPILE=riscv64-unknown-linux-gnu- \
     OPTIMIZE="-O3 -flto" \
     build-all -j `nproc`

• init data

make init

• collect result

bash scripts/collect.sh gcc

The gcc can be any name, only used as a suffix in the filename to tag the result.

With jemalloc

• compile jemalloc

export RISCV=/riscv_toolchain/top
git clone https://github.com/jemalloc/jemalloc.git
cd jemalloc
cp /path/to/jemalloc_cpp.patch ./ && git apply jemalloc_cpp.patch
CC=$RISCV/bin/riscv64-unknown-linux-gnu-gcc CXX=$RISCV/bin/riscv64-unknown-linux-gnu-c++ LD=$RISCV/bin/riscv64-unknown-linux-gnu-ld ./autogen.sh --prefix=$RISCV --host=x86_64-linux-gnu

make && make install

// prepare jemalloc compiled before
export RISCV=/riscv_toolchain/top
export LD_JEMALLOC=1
make ARCH=riscv64 \
     CROSS_COMPILE=riscv64-unknown-linux-gnu- \
     OPTIMIZE="-O3 -flto" \
     build-all -j `nproc`

Note for GCC >= 14

The old version of xerces-c in 483.xalancbmk contains a bug that will cause compile errors in GCC 14 and later. You may need to apply the following patch to SPEC CPU 2006 source code to get this fixed:

diff --git a/benchspec/CPU2006/483.xalancbmk/src/xercesc/util/NameIdPool.hpp b/benchspec/CPU2006/483.xalancbmk/src/xercesc/util/NameIdPool.hpp
