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 16.25 to 4.17 cycles (3.90x speedup).

Workaround

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

Vectorization

Your function is not vectorized. Only 34% 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 16.25 to 9.28 cycles (1.75x speedup).

Details

14% of VPU instructions are used in vector version (process two or more data elements in vector registers):

30% of VPU loads are used in vector version.
37% of VPU stores are used in vector version.
3% of VPU addition or subtraction instructions are used in vector version.
0% of VPU multiply instructions are used in vector version.
4% 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)

No data for this section

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.

Workaround

Avoid mixing data with different types. In particular, check if the type of constants is the same as array elements.

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

The binary function is composed of 1 FP arithmetical operations:

1: multiply

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 16.25 to 4.17 cycles (3.90x speedup).

Workaround

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

Vectorization

Details

14% of VPU instructions are used in vector version (process two or more data elements in vector registers):

30% of VPU loads are used in vector version.
37% of VPU stores are used in vector version.
3% of VPU addition or subtraction instructions are used in vector version.
0% of VPU multiply instructions are used in vector version.
4% 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)

Workaround

Avoid mixing data with different types. In particular, check if the type of constants is the same as array elements.

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

The binary function is composed of 1 FP arithmetical operations:

1: multiply

The binary function is loading 5 bytes. The binary function is storing 102 bytes.

Arithmetic intensity

Arithmetic intensity is 0.01 FP operations per loaded or stored byte.
