Migration Guide

This page describes how to port an application written using OpenMP Runtime 1.x to OpenMP Runtime 2.x.

Key Differences between OpenMP Runtime 1.x and 2.x

OpenMP runtime 2.x is configured by setting parameters in the OpenMP RTSC module. Refer to the sample application configuration file for details.

Porting an OpenMP Runtime 1.x Application to 2.x

  1. Switch to a platform file (Platform.xdc) supplied with 2.x
  2. Use the provided example application configuration file as a starting point to port OpenMP runtime 1.x configuration to corresponding 2.x parameters.
  3. If you are modifying the memory ranges specified in Platform.xdc: - Update OpenMP module parameters in the application configuration file to correspond to the new Platform file.
  4. OpenMP Runtime 1.x invokes the application main function as a BIOS Task and calls BIOS_start() before main. OpenMP runtime 2.x does not call main in the context of a BIOS Task. If the application uses Tasks, it must call BIOS_start().
