[ 0 / 9 ] Compilation options are not available

Compilation options are an important optimization leverage but ONE-View is not able to analyze them.

[ 4 / 4 ] Application profile is long enough (374.74 s)

To have good quality measurements, it is advised that the application profiling time is greater than 10 seconds.

[ 2 / 2 ] Application is correctly profiled ("Others" category represents 0.01 % of the execution time)

To have a representative profiling, it is advised that the category "Others" represents less than 20% of the execution time in order to analyze as much as possible of the user code

1327libgromacs_mpi.so.7Partial or unexisting vectorization - Use pragma to force vectorization and check potential dependencies between array access.51843.3896.4998.87
[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 128 issues (= instructions) costing 4 points each.512
[SA] Presence of a large number of scalar integer instructions - Simplify loop structure, perform loop splitting or perform unroll and jam. This issue costs 2 points.2
[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
[SA] Inefficient vectorization: use of masked instructions - Simplify control structure. The issue costs 2 points.2
Warning! There is no dynamic data for this loop. Some checks can not been performed.0
