Issue with deal.ii installation on Cori

[Vishwas Goel]

Hi, 

I am trying to install deal.ii on Cori using the following commands. However, the overall installation files run over 40 Gbs. Can you please let me know what could be the issue? I suspect I might be installing everything in deal.ii, which I might not even need.

$ wget https://dealii.43-1.org/downloads/dealii-9.2.0.tar.gz

$ tar xvzf dealii-9.2.0.tar.gz

$ cd dealii-9.2.0

$ mkdir build-executable

$ cd build-executable

$ cmake ..

$ make expand_instantiations_exe

$ export PATH="$PWD/bin:$PATH"

$ cd

$ mkdir dealii_install

$ mkdir build 

$ cd build

$ cmake -DCMAKE_INSTALL_PREFIX=~/dealii_install \

-DCMAKE_PREFIX_PATH=/opt/cray/pe/lib64 \

-DWITH_MPI=ON \

                -DMPI_DIR=/opt/cray/pe/mpt/default/gni/mpich-gnu/5.1/ \

                -DMPI_CXX_INCLUDE_PATH=/opt/cray/pe/mpt/default/gni/mpich-gnu/5.1/include/ \

                -DCMAKE_CXX_COMPILER=/opt/cray/pe/craype/2.6.2/bin/CC \

                -DCMAKE_C_COMPILER=/opt/cray/pe/craype/2.6.2/bin/cc \

                -DCMAKE_Fortran_COMPILER=/opt/cray/pe/craype/2.6.2/bin/ftn \

-DWITH_P4EST=ON -DP4EST_DIR=~/p4est_install/ \

        -DCMAKE_SYSTEM_NAME=CrayLinuxEnvironment \

~/dealii-9.2.0 

$ make -j 64 install

Vishwas,

A deal.II installation should not use that much disk space or are you talking about the memory being used while compiling? Every compilation unit uses a couple GB so running with 64 threads might be too much.

If it's the disk space, do you have any idea which directories are particularly large? Maybe, try only building in Release mode via CMAKE_BUILD_TYPE=Release.

Best,

Daniel

Dear Daniel,

Thanks for the quick response. I am talking about storage; since my storage allocation is only 40GBs, the installation aborts when it runs out of disk space. 

Yes! The bin directory under the build directory takes most of the space, about 32GBs. I can try that, but just to be sure, do you mean I should add this flag when I use the cmake command to create the make file?
