Tracing tool information
libKOMP includes the KAAPI tracing tool with capability to generate CSV files for various analysis. We do not promote a specific graphical interface! Use ggplot() and R for your analysis and various plots. Here related information for trace analysis (TODO):
- Generating CSV files
- R functions for reading CSV files
- R functions for Gantt chart
- R function for plotting distribution of the task executions time
- Playing with task informations contains in csv file

Here you can find some trcfile generated by on some applications
- Using Kastors benchmark dgetrf
- Same example with concurrent write used to improve paralelism
- PLASMA OMP version of dgetrf
- Same PLASMA OMP version of dgetrf with better internal blocking factor
- Stencil 2D, very small instances
