Settings

Legate Sparse has runtime settings that can be configured through environment variables.

fast-spgemm

Type:

bool (“0” or “1”)

Env var:

LEGATE_SPARSE_FAST_SPGEMM

Default:

False

Switch to faster CUSPARSE_SPGEMM_ALG1, which, however, use significantly more FB memory. It will be used by default when cusparse<12.1, where memory-restricted SpGEMM was introduced.
