6. Performance indicators of a calculation

For more information you can consult the user manual [U1.03.03]: “Calculation performance indicator (time/memory) “.

During a Code_Aster simulation, displays by default show certain dimensioning characteristics of the calculation in the message file (.mess). In particular, for each Aster operator, we find:

• The characteristics of the calculation (number of nodes, equations, Lagrange, size of the matrix… ),

• The JEVEUX floor memories (to switch to Out-Of-Core) and optimal memories (to switch to In-Core),

• The memory required by some external products (e.g. MUMPS),

• The times CPU, system and « user » (elapsed),

• The breakdown of the time consumed according to the calculation steps (elementary calculation, assembly, resolution of the linear system, unloading onto disk).

This last description of the time consumed can be broken down according to different reading levels (synthetic impression, detailed and detailed by calculation increment) via the parameter MESURE_TEMPS/NIVE_DETAIL of the DEBUT/POURSUITE commands. In parallel mode, we add the average value, on all the processors, of the times consumed as well as their standard deviation.
