Hello, I was just wondering how people compile Nektar++ from source on the IC cluster these days and if there are any recommended adjustments compared with that this link says https://www.nektar.info/nektar-cx1/ It is 4 years old but the instructions still work, it seems I'm able to compile Nektar++ with module load mpi/intel-2019.6.166 module load intel-suite/2017.6 module load fftw/3.3.3-double module load flex/2.6.4 module load scotch/6.0.4 module load boost/1.66.0 CC=mpicc CXX=mpicxx cmake -DNEKTAR_USE_FFTW=ON -DNEKTAR_USE_MKL=ON DNEKTAR_USE_MPI=ON -DNEKTAR_USE_SYSTEM_BLAS_LAPACK=OFF -DNEKTAR_TEST_FORCEMPIEXEC=ON -DCMAKE_CXX_FLAGS="-std=c++11 -O3 -xSSE4.2 -axAVX,CORE-AVX-I,CORE-AVX2" -DCMAKE_C_FLAGS="-O3 -xSSE4.2 -axAVX,CORE-AVX-I,CORE-AVX2" .. Would you recommend any change with respect to newer packages or better practice for efficiency? Thanks for the support, Thibaut
