The following improvements have been implemented:
- Option to stop in xerbla on error. This is controlled by
setting the environment variable BLIS_STOP_ON_ERROR=1
- Option to disable printing of error message from BLIS. This
is controlled by setting the environment variable
BLIS_PRINT_ON_ERROR=0
- Added a function to return the value of INFO passed to xerbla,
assuming xerbla was not set to stop on error. Example call is
info = bli_info_get_info_value();
The default behaviour remains to print but don't stop on error,
i.e. the equivalent to
export BLIS_PRINT_ON_ERROR=1 BLIS_STOP_ON_ERROR=0
Implementation details:
- Values of the environment variables are stored and retrieved
from global_rntm.
- Info value is stored and retrieved from tl_rntm. It is set
to 0 during initialization for all calls and updated by xerbla
if an error has occurred.
- Call to bli_init_auto before calling PASTEBLACHK macro (which
calls xerbla) will reinitialize info_value to 0 via call to
bli_thread_update_rntm_from_env
