Choose a directory to act as the root directory for your install. In this directory create a modules/ directory to contain your module file, coasted-gcc. Also create contrib/ and contrib/gcc/ directories to contain the compiled third party libraries.

Download the dependencies into the rCOASTEDoot directory

Copy the coasted-gcc file into the modules directory and edit it so that the lines defining COASTED_HOME, workDir and contribDir point to the directories coasted/, contrib/ and contrib/gcc/ respectively.

The directory tree should be:

[CoastED Root Directory]
   ├──  coasted/
   │  └──  [...Contents of Coasted Github repo...]
   ├──  contrib/
   │  └──  gcc/
   ├──  modules/
   │  └──  coasted-gcc
   ├──  ParMetis-3.2.0.tar.gz
   └──  petsc-3.6.4.tar.gz

Every time you use CoastED remember to use the coasted-gcc module:

$ module use /path/to/coasted/module/directory
$ module swap PrgEnv-cray coasted-gcc

You may wish to add the module use command into your .bashrc so that it is loaded at login.

Load the coasted-gcc module and (if you haven't already done so) extract Parmetis and cd into its directory.

Modify the Makefile.in so that CC and LD point to cc rather than mpicc. Then run make

Finally, copy libparmetis.a and libmetis.a to contrib/gcc/lib and copy parmetis.h to contrib/gcc/include.

Load coasted-gcc, extract PETSc into the root directory and cd into this. Copy build-petsc.sh into this directory and run it to compile PETSc (can take a while so get a cuppa 🍵 ☕). This should install PETSc to contrib/gcc/petsc/.

In the coasted directory, edit fldecomp/metis/Makefile to change CC=mpicc to CC=cc.

Copy coasted-build-gcc.sh into the coasted directory.

CoastED uses compile time optimisations. To that end we need to point a fluidity input file at the build script to successfully build CoastED. As an example we can use the one in channel-template in this repository.

./coasted-build-gcc.sh cto=/path/to/channel.flml

This should successfully build CoastED after an hour or so.

If the configuration step fails with Error. Currently, only optimisation for 2D is supported running dos2unix on the input file may help as Windows end of line characters confuse the build process.

It is advised to not use the coasted-gcc module for this, but instead use PrgEnv-gnu to prevent cmake from trying to link against PETSc libraries

Extract the tarball, cd into the newly extracted directory, and create a build/ directory. Move to this directory and run

$ cmake -DBLAS_LAPACK_LIBRARIES=/opt/cray/libsci/16.11.1/GNU/5.1/x86_64/lib/libsci_gnu.a -DCMAKE_INSTALL_PREFIX=/work/z01/z01/gpsgibb/coasted/contrib/gcc
$ make -j6
$ make install

(remembering to change the install prefix to your contrib/gcc/ directory) to build gmsh.
