Pierre,

petec and slepc libraries are found in the spack directory, but libhpddm_petsc is not. So it is not built during the spack install process.

... ...
./opt/spack/linux-sles15-zen3/gcc-12.3.0/petsc-3.21.0-tdljbqbgvde4zv6jr6tf7bbpae3rfkyg/lib/libpetsc.so
./var/spack/environments/demo1/.spack-env/._view/6rqhi7tgwui4fjo74fgkkyq4lklghged/lib/libpetsc.so

... ...
./opt/spack/linux-sles15-zen3/gcc-12.3.0/slepc-3.21.0-qhuhkznl5rlhqknsdqervlevup6xiuyt/lib/libslepc.so
./var/spack/environments/demo1/.spack-env/._view/6rqhi7tgwui4fjo74fgkkyq4lklghged/lib/libslepc.so

Thanks,
Cho

I used spack to install petsc with hpddm as follows.

o spack install petsc+hpddm
o spack install slepc ^petsc+hpddm

I got the following runtime error of finding the library hpddm_petsc.

argv0 -ksp_converged_reason -ksp_view_final_residual -ksp_type gmres -pc_type hpddm -ksp_monitor -log_view -options_left -device_view
$$$$$$$$$$$$$$ buildmatrix petsc
[6]PETSC ERROR: --------------------- Error Message --------------------------------------------------------------
[6]PETSC ERROR: Petsc has generated inconsistent data
[6]PETSC ERROR: /global/cfs/cdirs/ace3p/software/spack/var/spack/environments/demo1/.spack-env/view/lib/libhpddm_petsc not found

Is there something wrong with the install procedure?

The command lines look OK to me (but I don’t know Spack).
I’m not sure where things are being installed.
Could you please send the path to:
1) libpetsc.so
2) libslepc.so
3) libhpddm_petsc.so
If there is a mismatch between some of these, you may want to set the environment variable SLEPC_DIR or the command line parameter -hpddm_dir.

Thanks,
Pierre

Thanks,
Cho
