OpenMP Offload Best Practices
In this chapter we present best practices for improving the
performance of applications that offload onto the GPU. We organize the
best practices into the following categories, which are described in
the sections that follow:
Note:
Used the following when collecting OpenMP performance numbers:
- 2-tile Intel® GPU
- One GPU tile only (no implicit or explicit scaling).
- Internal versions of the Intel® compilers, runtimes, and GPU driver
- Level-Zero plugin
- Introduced a dummytargetconstruct at the beginning of a program, so as not to measure startup time.
- Just-In-Time (JIT) compilation mode.
