Vast.ai - Using GPU and CPU at same time!

[Gyfer]

Show the magic command that will make it works! 

Tested in WSL2 with 20.04 Focal Fossa.
First, remove previous old POCL 1.4 OCD

Code:

sudo apt remove pocl-opencl-icd

Then, install necessary dependencies and packages. Set LLVM to version 12 (latest available in apt search)

Code:

export LLVM_VERSION=12
sudo apt-get install -y python3-dev libpython3-dev build-essential ocl-icd-libopencl1 \
    cmake git pkg-config libclang-${LLVM_VERSION}-dev clang \
    llvm-${LLVM_VERSION} make ninja-build ocl-icd-libopencl1 ocl-icd-dev \
    ocl-icd-opencl-dev libhwloc-dev zlib1g zlib1g-dev clinfo dialog apt-utils \
    libxml2-dev libclang-cpp${LLVM_VERSION}-dev libclang-cpp${LLVM_VERSION} \
    llvm-${LLVM_VERSION}-dev \
    clang-12 git

Clone the POCL from github

Code:

cd ~
git clone https://github.com/pocl/pocl/

Ready to build cmake

Code:

cd ~/pocl
mkdir build && cd build
cmake ..
make
sudo make install

Copy over  ICD to /etc/OpenCL/vendors

Code:

sudo cp /usr/local/etc/OpenCL/vendors/pocl.icd /etc/OpenCL/vendors/pocl.icd

See the result

Code:

clinfo

Many thanks to @chuckity . Couldn't have get pocl to work if he didn't pointed out to copy over the ICD file.
