Constructor Detail

CpuCore

public CpuCore(int coreId,
               java.util.BitSet coreAffinity,
               CpuCore.LogicalCpu[] cpus)

Instantiate.

Parameters:

coreId - Core identifier.

coreAffinity - Affinity BitSet for all CpuCore.LogicalCpu instances on the CpuCore.

cpus - CpuCore.LogicalCpu instances for the CpuCore.

Method Detail

runWithCpuLayout

public static <R,T extends java.lang.Throwable> R runWithCpuLayout(net.openhft.affinity.CpuLayout layout,
                                                                         CpuCore.CustomExecution<R,T> customExecution)
                                                                  throws T extends java.lang.Throwable

Runs with custom CpuLayout.

This for example, allows restricting access to particular CPU cores or logical CPUs.

Type Parameters:

R - Return type.

T - Possible Throwable type.

Parameters:

layout - CpuLayout.

customExecution - CpuCore.CustomExecution.

Returns:

Possible return value.

Throws:

T - Failure on running.

T extends java.lang.Throwable
