[petsc-users] PETSc 2023 User Meeting and New Release 3.18

[Barry Smith]

We are pleased to announce the

 - next PETSc users meeting, June 5-7, 2023, in Chicago on the campus of IIT (mark your calendars, further information will be forthcoming soon) and the

 - release of PETSc version 3.18.0 at https://petsc.org/release/install/download/ <https://petsc.org/release/install/download/>.  This release includes

     + far more extensive solvers on GPUs, including an efficient MatSetValuesCOO() for setting matrix values directly on the GPU

     + improved interfaces to Kokkos, so user GPU code can now be written in Kokkos, CUDA, or HIP.

     + vastly improved documentation at petsc.org with a more comprehensive user manual and better search capabilities (due to Patrick Sanan)

We recommend upgrading to PETSc 3.18.0 soon. As always, please report problems to  petsc-maint at mcs.anl.gov <mailto:petsc-maint at mcs.anl.gov> and ask questions at petsc-users at mcs.anl.gov <mailto:petsc-users at mcs.anl.gov>

A list of the major changes and updates can be found at https://petsc.org/release/docs/changes/318 <https://petsc.org/release/docs/changes/318>
