Environment variables

This topic lists the environment variables that enable testing, debugging, and experimental features for Tensile clients and applications.

Environment variable	Value
TENSILE_DB Enables debugging features based on the supplied value. Bit field options can be set individually or combined.	Hexadecimal bit field values: 0x2 or 0x4: Solution selection process information 0x8: Hardware selection process information 0x10: Predicate evaluation debug information 0x20: Code object library loading status 0x40: Kernel launch arguments and parameters 0x80: Allocated tensor sizes 0x100: Convolution reference calculation debug info 0x200: Detailed convolution reference calculations 0x1000: Library loading information (YAML/MessagePack) 0x4000: Solution lookup efficiency 0x8000: Selected kernel names 0x80000: Detailed kernel parameters (Matrix Instruction, MacroTile, etc.) 0xFFFF: Enable all debug output
TENSILE_DB2 Enables extended debugging features. Skips kernel launches but continues kernel selection and data allocation.	1: Enable extended debugging 2: Disable extended debugging
TENSILE_NAIVE_SEARCH Performs naive search for matching kernels instead of optimized search.	1: Enable naive search 2: Disable naive search
TENSILE_TAM_SELECTION_ENABLE Enables tile aware solution selection.	1: Enable tile aware selection 2: Disable tile aware selection
TENSILE_SOLUTION_INDEX Prints the index of the selected solution.	1: Enable solution index printing 2: Disable solution index printing
TENSILE_METRIC Overrides the default distance matrix for solution selection.	“Euclidean”: Euclidean distance metric “JSD”: Jensen-Shannon divergence metric “Manhattan”: Manhattan distance metric “Ratio”: Ratio-based metric “Random”: Random selection metric
TENSILE_PROFILE Enables profiling of functions decorated with @profile decorator. Results generated as .prof files.	1, “ON”, “TRUE”: Enable profiling Any other value: Disable profiling
