Class dsp::test::TransferCUDATestHelper

class TransferCUDATestHelper

Facilitates the transfer of TimeSeries to/from GPU.

Public Functions

TransferCUDATestHelper(Memory *memory = 0, cudaStream_t stream = 0)

Construct a new TransferCUDATestHelper object.

Note that the memory attribute must be CUDA::DeviceMemory instance if a host to device transfer is used by the helper.

Parameters:

  • memory – optional memory manager that will allocate memory on device

  • stream – optional CUDA stream in which transfers will be scheduled

~TransferCUDATestHelper() = default

Destroy the TransferCUDATestHelper object.

void copy(dsp::TimeSeries *into, const dsp::TimeSeries *from, cudaMemcpyKind direction)

Copy data from one TimeSeries to another, either from device to host or vice versa.

Parameters:

  • into – TimeSeries into which data will be copied

  • from – TimeSeries from which data will be copied

  • direction – the kind of transfer (device to host, or host to device)

Post:

If direction == cudaMemcpyHostToDevice and this->memory has been set, then the memory manager of out will be set to CUDA::DeviceMemory

void copy_bitseries(dsp::BitSeries *into, const dsp::BitSeries *from, cudaMemcpyKind direction)

Copy data from one BitSeries to a another, either from device to host or vice versa.

Parameters:

  • into – BitSeries into which data will be copied

  • from – BitSeries from which data will be copied

  • direction – the kind of transfer (device to host, or host to device)

Post:

If direction == cudaMemcpyHostToDevice and this->memory has been set, then the memory manager of out will be set to CUDA::DeviceMemory
