The size of the key is limited (see documentation). The given value is copied by LIBXSMM and can be initialized prior to registration or whenever queried. Registered data is released when the program terminates but can be also released if needed (libxsmm_xrelease), .e.g., in case of a larger value reusing the same key.

public pure subroutine libxsmm_matdiff(info, datatype, m, n, ref, tst, ldref, ldtst)

Utility function to calculate a collection of scalar differences between two matrices (libxsmm_matdiff_info). The location (m, n) of the largest difference (linf_abs) is recorded (also if NaN). In case of NaN, differences are set to infinity. If no difference is discovered, the location (m, n) is negative (OOB).
