Code clean check

Detected a slowdown caused by scalar integer instructions (typically used for address computation). By removing them, you can lower the cost of an iteration from 20.00 to 15.50 cycles (1.29x speedup).

Workaround

Try to reorganize arrays of structures to structures of arrays
Consider to permute loops (see vectorization gain report)

Vectorization

Your function is poorly vectorized. Only 33% of vector register length is used (average across all VPU instructions).

Details

28% of VPU instructions are used in vector version (process two or more data elements in vector registers):

41% of VPU loads are used in vector version.
38% of VPU stores are used in vector version.
0% of VPU addition or subtraction instructions are used in vector version.
43% of VPU fused multiply-add instructions are used in vector version.
3% of VPU instructions that are not load, store, addition, subtraction nor multiply instructions are used in vector version.

FMA

Detected 22 FMA (fused multiply-add) operations.

CALL instructions

Detected function call instructions.

Details

Calling (and then returning from) a function prevents many compiler optimizations (like vectorization), breaks control flow (which reduces pipeline performance) and executes extra instructions to save/restore the registers used inside it, which is very expensive (dozens of cycles). Consider to inline small functions.

Matching between your function (in the source code) and the binary function

The binary function is composed of 44 FP arithmetical operations:

22: addition or subtraction (all inside FMA instructions)
22: multiply (all inside FMA instructions)

The binary function does not load or store any data.

Workaround

Try to reorganize arrays of structures to structures of arrays
Consider to permute loops (see vectorization gain report)

Vectorization

Your function is poorly vectorized. Only 33% of vector register length is used (average across all VPU instructions).

Details

28% of VPU instructions are used in vector version (process two or more data elements in vector registers):

41% of VPU loads are used in vector version.
38% of VPU stores are used in vector version.
0% of VPU addition or subtraction instructions are used in vector version.
43% of VPU fused multiply-add instructions are used in vector version.
3% of VPU instructions that are not load, store, addition, subtraction nor multiply instructions are used in vector version.

FMA

Detected 22 FMA (fused multiply-add) operations.

CALL instructions

Detected function call instructions.

Matching between your function (in the source code) and the binary function

The binary function is composed of 44 FP arithmetical operations:

22: addition or subtraction (all inside FMA instructions)
22: multiply (all inside FMA instructions)

The binary function does not load or store any data.
