[petsc-dev] Statistics on the popularity of PETSc

[Barry Smith]

  Jacob,

    Cool feature,

$ brew info openmpi
open-mpi: stable 4.0.5 (bottled), HEAD
High performance message passing library
https://www.open-mpi.org/
Conflicts with:
  mpich (because both install MPI compiler wrappers)
Not installed
From: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/open-mpi.rb

Required: gcc ✔, hwloc ✘, libevent ✔

install: 24,409 (30 days), 72,362 (90 days), 205,281 (365 days)
install-on-request: 6,116 (30 days), 17,393 (90 days), 49,467 (365 days)
build-error: 0 (30 days)

  So we could say roughly 3% of brew OpenMPI users use PETSc ?  Pretty low. But I'm not surprised, my impression is that the huge bulk of MPI users don't really use MPI based libraries.

  For hypre it is 381/49467 < 1%

  For scalapack 1,455/49467 remarkably close to PETSc's number.

 I could not find superlu_dist, trilinos or MUMPs.

 We should push harder on making PETSc available through packaging systems, we can discuss this once we have our Community engagement group going.

  Barry
