Method Detail

setAffinity

public static void setAffinity(long mask)

Sets the CPU affinity mask of the current thread to mask. Only works on machines with at most 64 processors. For larger ranges of CPUs use setAffinityBitSet.

Parameters:

mask - The CPU affinity mask

Throws:

UnsupportedOperationException - If the operating system is not supported by this library.

IllegalArgumentException - If the mask contains no processors that are currently physically on the system and permitted to the current thread.

setAffinityBitSet

public static void setAffinityBitSet(BitSet mask)

Sets the CPU affinity mask of the current thread to mask.

Parameters:

mask - The CPU affinity mask

Throws:

UnsupportedOperationException - If the operating system is not supported by this library.

IllegalArgumentException - If the mask contains no processors that are currently physically on the system and permitted to the current thread.

getAffinity

public static long getAffinity()

Gets the CPU affinity mask of the current thread as a long. Only works on machines with at most 64 processors. For larger ranges of CPUs use getAffinityBitSet.

Throws:

UnsupportedOperationException - If the operating system is not supported by this library.

getAffinityBitSet

public static BitSet getAffinityBitSet()

Gets the CPU affinity mask of the current thread as a long.

Throws:

UnsupportedOperationException - If the operating system is not supported by this library.
