Performance Analysis
The following tools are provided to display additional execution information.
PROGINF
PROGINF provides program execution analysis information throughout the execution of program.
To use PROGINF compile your C code using ncc. The PROGINF-library is linked by default.
When setting VE_PROGINF to YES or DETAIL at runtime, additional information will be displayed.
For additional information see the PROGINF and FTRACE users guide.
FTRACE
FTRACE is used to obtain performance information such as the CPU usage and vectorization
aspect of each function in a program, as well as user regions.
To use FTRACE compile your C code using ncc with the -ftrace flag.
When executing, a ftrace.out.* file is generated, which can be viewed using ftrace -f ftrace.out.*.
For additional information see the PROGINF and FTRACE users guide
and the NEC FTRACE Viewer users guide.
To pass the -ftrace flag to ncc while using our OpenMP offloading implementation use the -Xopenmp-target clang flag as described in Passing Arguments to the Target Compiler.
