Optionally enable parallelism inside gtestsuite so that we can
check BLIS functions perform correctly when nested parallelism
is in operation. Enable with:
cmake ... -DOPENMP_NESTED={0,1,2,1diff}
where in gtestsuite
- 0 is the default choice with no parallelism.
- 1 and 2 are simple nested parallelism.
- 1diff has one level of parallelism setting different numbers
of threads to be used by BLIS and reference library calls
from each gtestsuite thread.
Note: OMP_NUM_THREADS must be set appropriately to enable or
disable parallelism at each level in the test programs
as desired.
OMP_NUM_THREADS will also define the parallelism used
within the BLIS library (if it is multithreaded), unless
BLIS-specific ways of specifying parallelism have been
used. If a BLIS-specific parallelism option has been set,
the same mechanism will be used in the 1diff option to
vary the number of threads in BLIS per application thread.
