|
### Install development tools
|
|
$ sudo apt-get install build-essential
|
|
$ sudo apt-get install git
|
|
### Install Vortex codebase
|
|
$ git clone --recursive https://github.com/vortexgpgpu/vortex.git
|
|
$ cd Vortex
|
|
### Install prebuilt toolchain
|
|
$ ./ci/toolchain_install.sh --all
|
|
|
|
By default, the toolchain will install to /opt folder.
|
|
You can install the toolchain to a different directory by overiding DESTDIR.
|
|
|
|
$ DESTDIR=$TOOLDIR ./ci/toolchain_install.sh --all
|
|
$ export VORTEX_HOME=$TOOLDIR/vortex
|
|
$ export LLVM_VORTEX=$TOOLDIR/llvm-vortex
|
|
$ export LLVM_POCL=$TOOLDIR/llvm-pocl
|
|
$ export RISCV_TOOLCHAIN_PATH=$TOOLDIR/riscv-gnu-toolchain
|
|
$ export VERILATOR_ROOT=$TOOLDIR/verilator
|
|
$ export PATH=$VERILATOR_ROOT/bin:$PATH
|
|
### Build Vortex sources
|
|
$ make -s
|
|
### Quick demo running vecadd OpenCL kernel on 2 cores
|
|
$ ./ci/blackbox.sh --cores=2 --app=vecadd
