cuquantum.cutensornet.contract_slices¶
- cuquantum.cutensornet.contract_slices(intptr_t handle, intptr_t plan, raw_data_in, intptr_t raw_data_out, bool accumulate_output, intptr_t workspace, intptr_t slice_group, intptr_t stream)[source]¶
Perform the contraction of the input tensors.
The input tensors should form a tensor network that is prescribed by the tensor network descriptor that was used to create the contraction plan.
This version of the contraction API takes a group of slices instead of a single slice.
- Parameters
handle (intptr_t) – The library handle.
plan (intptr_t) – The contraction plan handle.
raw_data_in –
A host array of pointer addresses (as Python
int
) for each input tensor (on device). It can beraw_data_out (intptr_t) – The pointer address (as Python
int
) to the output tensor (on device).accumulate_output (bool) – Whether to accumulate the data in
raw_data_out
.workspace (intptr_t) – The workspace descriptor.
slice_group (intptr_t) – The slice group descriptor.
stream (intptr_t) – The CUDA stream handle (
cudaStream_t
as Pythonint
).
