Enum CudaDevice.Limit

java.lang.Object

java.lang.Enum<CudaDevice.Limit>

com.ibm.cuda.CudaDevice.Limit

All Implemented Interfaces:

Serializable, Comparable<CudaDevice.Limit>

Enclosing class:

CudaDevice

public static enum CudaDevice.Limit
extends Enum<CudaDevice.Limit>

Limit identifies device limits that may be queried or configured.

Enum Constant Detail

DEV_RUNTIME_PENDING_LAUNCH_COUNT

public static final CudaDevice.Limit DEV_RUNTIME_PENDING_LAUNCH_COUNT

maximum number of outstanding device runtime launches that can be made from this context

DEV_RUNTIME_SYNC_DEPTH

public static final CudaDevice.Limit DEV_RUNTIME_SYNC_DEPTH

maximum grid depth at which a thread can issue the device runtime call ::cudaDeviceSynchronize() to wait on child grid launches to complete

MALLOC_HEAP_SIZE

public static final CudaDevice.Limit MALLOC_HEAP_SIZE

size in bytes of the heap used by the ::malloc() and ::free() device system calls

PRINTF_FIFO_SIZE

public static final CudaDevice.Limit PRINTF_FIFO_SIZE

size in bytes of the FIFO used by the ::printf() device system call

Method Detail

values

public static CudaDevice.Limit[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (CudaDevice.Limit c : CudaDevice.Limit.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static CudaDevice.Limit valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
