• Scalable Many-to-Many (neighborhood) gather-scatter collectives
• Robust GLL interpolation on hexahedral spectral element meshes

The build system relies on GNU Make with the make command. To compile gslib just run:

make CC=mpicc

Different make options are available (see Makefile).

[2] CEED: Co-design center for Efficient Exascale Discretizations.

[3] Nektar++: Nektar++ open-source spectral/hp element code.

[4] Libparanumal: Accelerated finite element flow solvers .
