Vectorization

Your loop is highly vectorized. 97% of vector register length is used (average across all VPU instructions).

Details

94% of VPU instructions are used in vector version (process two or more data elements in vector registers):

0% of VPU instructions that are not load, store, addition, subtraction nor multiply instructions are used in vector version.

FMA

Detected 32 FMA (fused multiply-add) operations. Presence of both ADD/SUB and MUL operations.

Workaround

Try to change order in which elements are evaluated (using parentheses) in arithmetic expressions containing both ADD/SUB and MUL operations to enable your compiler to generate FMA instructions wherever possible. For instance a + b*c is a valid FMA (MUL then ADD). However (a+b)* c cannot be translated into an FMA (ADD then MUL).

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

The binary loop is composed of 120 FP arithmetical operations:

52: addition or subtraction (32 inside FMA instructions)
68: multiply (32 inside FMA instructions)

The binary loop is loading 384 bytes.

Arithmetic intensity

Arithmetic intensity is 0.31 FP operations per loaded or stored byte.

Cycles and memory resources usage

Assuming all data fit into the L1 cache, each iteration of the binary loop takes 11.50 cycles. At this rate:

34% of peak load performance is reached (33.39 out of 96.00 bytes loaded per cycle (GB/s @ 1GHz))

ASM code

In the binary file, the address of the loop is: 424180
