This set of instructions is intended for 64-bit Linux computers. MacOS support is in the works.
Make sure your system has the basics to build software.
On Debian derivatives (Ubuntu and many more), installing
build-essentialshould do the trick.
Everywhere else, just making sure you have the
g++package should be enough.
curl -L -O https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-$(uname)-$(uname -m).sh # then run bash ./Miniforge3-*.sh
If you accepted the default location, this should work:
$CONDA/bin/conda create -n dgfem
source $CONDA/bin/activate dgfem
conda install git pip pocl islpy pyopencl
Type the following command:
hash -r; for i in pymbolic cgen genpy modepy pyvisfile loopy arraycontext meshmode dagrt leap grudge; do python -m pip install --editable "git+https://github.com/inducer/$i.git#egg=$i"; done
In each case, you may leave out the
--editable flag if you would not like
an editable copy of the source code checked out in a subfolder.
Next time you want to use grudge, just run the following command:
source /WHERE/YOU/INSTALLED/miniforge3/bin/activate dgfem
You may also like to add this to a startup file (like
$HOME/.bashrc) or create an alias for it.
Troubleshooting the Installation#
/usr/bin/ld: cannot find -lstdc++#
sudo apt-get install libstdc++-6-dev
to install the missing C++ development package.
No CL platforms found/unknown error -1001#
If you get:
pyopencl.cffi_cl.LogicError: clGetPlatformIDs failed: <unknown error -1001>
conda update ocl-icd pocl
(This indicates that the OpenCL driver loader didn’t find any drivers, or the drivers were themselves missing dependencies.)
Assertion ‘error == 0’#
If you get:
/opt/conda/conda-bld/home_1484016200338/work/pocl-0.13/lib/CL/devices/common.c:108: llvm_codegen: Assertion 'error == 0 ' failed. Aborted (core dumped)
then you’re likely out of memory.
