Compression/Decompression¶
The following section describes oneDTL ZFP compression and decompression main functions.
Encode¶
encode function must be provided to perform encoding of the zfp_field to zfp_compressed_stream
-
template<typename DataT, std::uint32_t Dimension>
sycl::event oneapi::dtl::data_compression::encode(sycl::queue &queue, zfp_field<DataT, Dimension> &source, zfp_compressed_stream<DataT, Dimension> &stream)¶ Encodes field to stream.
- Template Parameters
DataT – field data type (supported types: float)
Dimension – field dimension (supported value: 3)
- Parameters
queue – SYCL queue object to make encode
source – input field
stream – compressed stream
- Returns
SYCL event
Decode¶
decode function must be provided to perform decoding of the zfp_compressed_stream to zfp_field
-
template<typename DataT, std::uint32_t Dimension>
sycl::event oneapi::dtl::data_compression::decode(sycl::queue &queue, zfp_compressed_stream<DataT, Dimension> &stream, zfp_field<DataT, Dimension> &destination)¶ Decodes stream to field.
- Template Parameters
DataT – field data type (supported types: float)
Dimension – field dimension (supported value: 3)
- Parameters
queue – SYCL queue object to make decode
stream – compressed stream
destination – output field
- Returns
SYCL event
