# Baseline-MG

Baseline programs to invoke hypre's multigrids including SMG, PFMG, SysPFMG, and BoomerAMG to solve the same problems as StructMG.

- File base\_struct.c invokes SMG and PFMG through Struct interface.
- File base\_sstruct.c invokes SysPFMG through SStruct interface.
- File base\_IJ.c invokes BoomerAMG through IJ interface.

The specific parameters to invoke different multigrids for different problems could be found in these files with calls of HYPRE\_* functions.

Dependency: hypre (version 2.25.0) libraries of different precisions.

## Compile

Makefile specifies compile and link options for hypre libraries of different precisions on both ARM and X86 platforms.

## Run

Similar to StructMG (https://gitee.com/zongy17/smg/blob/master/README.md), tests of baseline programs could be run by the following example commands.

- SMG: salloc -N _Node_ --exclusive mpirun --mca io romio321 -rf _rankfile_ _executable_ _case\_name_ _cx_ _cy_ _cz_ _px_ _py_ _pz_ SMG
- PFMG: salloc -N _Node_ --exclusive mpirun --mca io romio321 -rf _rankfile_ _executable_ _case\_name_ _cx_ _cy_ _cz_ _px_ _py_ _pz_ PFMG
- BoomerAMG: salloc -N _Node_ --exclusive mpirun --mca io romio321 -rf _rankfile_ _executable_ _case\_name_ _cx_ _cy_ _cz_
- SysPFMG: salloc -N _Node_ --exclusive mpirun --mca io romio321 -rf _rankfile_ _executable_ _case\_name_ _cx_ _cy_ _cz_ _px_ _py_ _pz_ SysPFMG

where _Node_ is the number of computing nodes, and _rankfile_ is the MPI rankfiles to assign processes and threads' binding, and _cx_, _cy_, and _cz_ are case sizes of three dimensions in a test, and _px_, _py_, and _pz_ are process partisions in three dimensions.

These test configurations refer to test\_config.md in the repositories.

For both StructMG and baseline programs, processes partition a problem with strictly-balanced loads across them.
