Method Detail

getAvailableMemory

public abstract long getAvailableMemory()

Gets device memory available for SystemML operations

Returns:

available memory

ensureComputeCapability

public abstract void ensureComputeCapability()
                                      throws DMLRuntimeException

Ensures that all the CUDA cards on the current system are of the minimum required compute capability. (The minimum required compute capability is hard coded in JCudaContext.

Throws:

DMLRuntimeException - if DMLRuntimeException occurs

getGPUContext

public static GPUContext getGPUContext()
                                throws DMLRuntimeException

Singleton Factory method for creation of GPUContext

Returns:

GPU context

Throws:

DMLRuntimeException - if DMLRuntimeException occurs

createGPUObject

public static GPUObject createGPUObject(org.apache.sysml.runtime.controlprogram.caching.MatrixObject mo)

destroy

public abstract void destroy()
                      throws DMLRuntimeException

Throws:

DMLRuntimeException
