---|---|---|
|
Instruction accesses the same memory from iteration to iteration. |
Represents the ideal situation and does not require any improvements. |
|
Instruction accesses memory that consistently changes by one element from iteration to iteration. |
Represents the ideal situation and does not require any improvements. |
|
Instruction accesses memory that consistently changes by N elements (N>1) from iteration to iteration. |
Code uses more memory than is ideal and requires more cache lines. Consider studying recommendations on AOS/SOA optimization. |
|
Instruction accesses memory addresses that change by an unpredictable number of elements from iteration to iteration. |
Might limit vectorization or even make it impossible. |
|
Intel Advisor detected for v(p)gather* instructions on AVX2 Instruction Set Architecture. |
The compiler vectorized code with an irregular memory access pattern. Consider improving the code to use a more constant memory access pattern. |
