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 16.50 to 10.50 cycles (1.57x 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 39% of vector register length is used (average across all VPU instructions). By fully vectorizing your function, you can lower the cost of an iteration from 16.50 to 11.95 cycles (1.38x speedup).

Details

20% of VPU instructions are used in vector version (process two or more data elements in vector registers):

33% of VPU loads are used in vector version.
20% of VPU stores are used in vector version.
41% of VPU addition or subtraction instructions are used in vector version.
10% of VPU instructions that are not load, store, addition, subtraction nor multiply instructions are used in vector version.

Since your execution units are vector units, only a fully vectorized function can use their full power.

Workaround

Try another compiler or update/tune your current one
Make array accesses unit-stride:
- If your function streams arrays of structures (AoS), try to use structures of arrays instead (SoA): for(i) a[i].x = b[i].x; (slow, non stride 1) => for(i) a.x[i] = b.x[i]; (fast, stride 1)

Expensive FP math instructions/calls

Detected performance impact from expensive FP math instructions/calls. By removing/reexpressing them, you can lower the cost of an iteration from 16.50 to 1.50 cycles (11.00x speedup).

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

The binary function is composed of 28 FP arithmetical operations:

28: addition or subtraction

The binary function is loading 196 bytes. The binary function is storing 108 bytes.

Arithmetic intensity

Arithmetic intensity is 0.09 FP operations per loaded or stored byte.

Workaround

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

Vectorization

Details

20% of VPU instructions are used in vector version (process two or more data elements in vector registers):

33% of VPU loads are used in vector version.
20% of VPU stores are used in vector version.
41% of VPU addition or subtraction instructions are used in vector version.
10% of VPU instructions that are not load, store, addition, subtraction nor multiply instructions are used in vector version.

Since your execution units are vector units, only a fully vectorized function can use their full power.

Workaround

Try another compiler or update/tune your current one
Make array accesses unit-stride:
- If your function streams arrays of structures (AoS), try to use structures of arrays instead (SoA): for(i) a[i].x = b[i].x; (slow, non stride 1) => for(i) a.x[i] = b.x[i]; (fast, stride 1)

Expensive FP math instructions/calls

Detected performance impact from expensive FP math instructions/calls. By removing/reexpressing them, you can lower the cost of an iteration from 16.50 to 1.50 cycles (11.00x speedup).

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

The binary function is composed of 28 FP arithmetical operations:

28: addition or subtraction

The binary function is loading 196 bytes. The binary function is storing 108 bytes.

Arithmetic intensity

Arithmetic intensity is 0.09 FP operations per loaded or stored byte.
