Detailed Description

Function Documentation

void affinity_finalize ( )

Destroy affinity information structure.

Destroys the affinity information structure AffinityDomains_t. Retrieved pointers to the structures are not valid anymore after this function call

void affinity_init ( )

Initialize affinity information.

Initialize affinity information AffinityDomains_t using the data of the structures CpuInfo_t, CpuTopology_t and NumaTopology_t

void affinity_pinProcess ( int processorId )

Pin process to a CPU.

Pin process to a CPU. Duplicate of likwid_pinProcess()

Parameters

[in] processorId CPU ID for pinning

Pin processes to a CPU.

Pin processes to a CPU. Creates a cpuset with the given processor IDs

Parameters

[in]	cpu_count	Number of processors in processorIds
[in]	processorIds	Array of processor IDs

void affinity_pinThread ( int processorId )

Pin thread to a CPU.

Pin thread to a CPU. Duplicate of likwid_pinThread()

Parameters

[in] processorId CPU ID for pinning

int affinity_processGetProcessorId ( )

Return the CPU ID where the current process runs.

int affinity_threadGetProcessorId ( )

Return the CPU ID where the current thread runs.

AffinityDomains_t get_affinityDomains ( void )

Retrieve affinity structure.

Get the previously initialized affinity info structure
