Vectorization

Your loop is highly vectorized. 100% of vector register length is used (average across all VPU instructions).

Details

92% of VPU instructions are used in vector version (process two or more data elements in vector registers):

50% of VPU instructions that are not load, store, addition, subtraction nor multiply instructions are used in vector version.

FMA

Detected 8 FMA (fused multiply-add) operations.

Slow data structures access

Detected data structures (typically arrays) that cannot be efficiently read/written

Details

Constant unknown stride: 4 occurrence(s)

Non-unit stride (uncontiguous) accesses are not efficiently using data caches

Workaround

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

Conversion instructions

Detected expensive conversion instructions.

Details

UCVTF: 1 occurrences►
- /home/eoseret/qaas/qaas_runs/178-177-5622/intel/HACCmk/build/HACCmk/src/main.c:119

Workaround

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

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

The binary loop is composed of 64 FP arithmetical operations:

56: addition or subtraction (8 inside FMA instructions)
8: multiply (all inside FMA instructions)

The binary loop is storing 128 bytes.

Arithmetic intensity

Arithmetic intensity is 0.50 FP operations per loaded or stored byte.
