Description

maxM

Input

Maximum value of singleCoreM. The default value is -1. The value -1 indicates that the maximum value of singleCoreM is not set. Instead, it is calculated by the tiling function.

maxN

Input

Maximum value of singleCoreN. The default value is -1. The value -1 indicates that the maximum value of singleCoreN is not set. Instead, it is calculated by the tiling function.

maxK

Input

Maximum value of singleCoreK. The default value is -1. The value -1 indicates that the maximum value of singleCoreK is not set. Instead, it is calculated by the tiling function.

minM

Input

Minimum singleCoreM value. The default value is -1. The value -1 indicates that the minimum value of singleCoreM is not set. Instead, it is calculated by the tiling function.

minN

Input

Minimum singleCoreN value. The default value is -1. The value -1 indicates that the minimum value of singleCoreN is not set. Instead, it is calculated by the tiling function.

minK

Input

Minimum singleCoreK value. The default value is -1. The value -1 indicates that the minimum value of singleCoreK is not set. Instead, it is calculated by the tiling function.

Returns

-1: setting failed; 0: setting succeeded.
