Hi,Mark,
When testing the heev interface using the test program, with 4 processes, dim=1000, and nb=384 as the test case parameters, the results were incorrect. Specific details are as follows:
[mshuangzd@b08r3n11 test]$ mpirun -n 4 ./tester --dim 1000 --nb 384 --ref y heev
% SLATE version 2023.11.05, id f1c8490
% input: ./tester --dim 1000 --nb 384 --ref y heev
% 2024-12-06 23:50:27, 4 MPI ranks, CPU-only MPI, 1 OpenMP threads, 4 GPU devices per MPI rank
type origin target eig A jobz uplo n nb ib p q la pt value err back err Z orth. time (s) ref time (s) status
d host task dc 1 novec lower 1000 384 32 2 2 1 1 3.61e-02 NA NA 2.913 0.326 FAILED
% Matrix kinds:
% 1: rand, cond unknown
% 1 tests FAILED: heev
--------------------------------------------------------------------------
Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.
--------------------------------------------------------------------------
--------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:
Process name: [[50583,1],0]
Exit code: 1
