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):

82% of VPU addition or subtraction instructions are used in vector version.

No data for this section

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

The binary loop is composed of 28 FP arithmetical operations:

28: addition or subtraction

The binary loop is loading 448 bytes. The binary loop is storing 224 bytes.

Arithmetic intensity

Arithmetic intensity is 0.04 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 14.00 cycles. At this rate:

33% of peak load performance is reached (32.00 out of 96.00 bytes loaded per cycle (GB/s @ 1GHz))
33% of peak store performance is reached (16.00 out of 48.00 bytes stored per cycle (GB/s @ 1GHz))

ASM code

In the binary file, the address of the loop is: 4db580

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):

82% of VPU addition or subtraction instructions are used in vector version.

No data for this section

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

The binary loop is composed of 28 FP arithmetical operations:

28: addition or subtraction

The binary loop is loading 448 bytes. The binary loop is storing 224 bytes.

Arithmetic intensity

Arithmetic intensity is 0.04 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 14.00 cycles. At this rate:

33% of peak load performance is reached (32.00 out of 96.00 bytes loaded per cycle (GB/s @ 1GHz))
33% of peak store performance is reached (16.00 out of 48.00 bytes stored per cycle (GB/s @ 1GHz))
