6 months ago The default size (256MB) to use GPU memory exceeded. You can increase it to something a lot larger by setting the environment variable: export SUPERLU_MAX_BUFFER_SIZE=1024000000
This paper describes the user-tunable parameters, esp. for GPU: https://dl.acm.org/doi/full/10.1145/3577197
When i run audikw_1.mtx on superlu_dist with 32 rank, i get an assert : pdgstrf: Assertion `nbrow*(st_col+num_col_stream) < buffer_size' failed. what is this mean ang how can i fix it
