API Calling Example

This section provides sample code for calling HMPP interface functions to help you quickly get started with the library. All the sample code provided in this document references the HMPP header file hmpp.h.

  1. Create a test.cpp file.
  2. Add the following code to the test.cpp file.

Example of Compiling and Executing the File

  1. Compile the file.
    1
    g++ test.cpp -o test -L /usr/local/kml/lib/neon -lkfft -lkfftf -L /usr/local/kml/lib/noarch/kvml/single -lkvml -L /usr/local/kml/lib/noarch/ -lkm -lm -L /usr/local/kml/lib/neon/kblas/locking -lkblas -L /usr/local/lib/HMPP -lHMPP_signal -lHMPP_core -lpthread
  2. Execute the file.
    1
    ./test
