5execPartial or unexisting vectorization - Use pragma to force vectorization and check potential dependencies between array access.7699.887.2340.16
[SA] Presence of expensive FP instructions - Perform hoisting, change algorithm, use SVML or proper numerical library or perform value profiling (count the number of distinct input values). There are 16 issues (= instructions) costing 4 points each.64
[SA] Presence of special instructions executing on a single port (INSERT/EXTRACT, BROADCAST, MASKMOV/MOV2M) - Simplify data access and try to get stride 1 access. There are 10 issues (= instructions) costing 1 point each.10
[SA] Inefficient vectorization: use of shorter than available vector length - Force compiler to use proper vector length. CAUTION: use of 512 bits vectors could be more expensive than 256 bits on some processors. Use intrinsics (costly and not portable). The issue costs 2 points.2
4execPartial or unexisting vectorization - Use pragma to force vectorization and check potential dependencies between array access.30.0206.82
[SA] Presence of constant non unit stride data access - Use array restructuring, perform loop interchange or use gather instructions to lower a bit the cost. There are 1 issues ( = data accesses) costing 2 point each.2
[SA] Presence of calls - Inline either by compiler or by hand and use SVML for libm calls. There are 1 issues (= calls) costing 1 point each.1
