Performance Optimization APIs
Intel® Resource Director Technology (RDT) provides a set of resource allocation (or control) capabilities, including Cache Allocation Technology (CAT) and Memory Bandwidth Allocation (MBA):
- CAT allows RTX64 to allocate L3 cache or L2 cache for each logical processor.
- MBA allows RTX64 to control the memory bandwidth that is available for each core.
These real-time functions can be used to configure RDT performance optimization.
| Function | Description |
|---|---|
| RtGetRDTCapability | Returns the system Resource Director Technology (RDT) allocation capability. |
| RtSetThreadCLOS | Overwrites a thread’s implicit or default Class of Services (CLOS), which is based on its priority. |
| RtGetThreadCLOS | Retrieves the Class of Services (CLOS) value of a specified thread. |
