Member Function Documentation

◆ decodeArray()

virtual const uint32_t* genie::compression::DeviceIntegerCODEC::decodeArray ( const uint32_t *  in,
const size_t  length,
uint32_t *  out,
size_t &  nvalue 
)
pure virtual

Implemented in genie::compression::DeviceDeltaCodec, genie::compression::DeviceBitPackingPrefixedCodec, genie::compression::DeviceCopyCodec, genie::compression::DeviceCopyMultiblockCodec, genie::compression::DeviceBitPackingCodec, genie::compression::DeviceSerialCodec< Codec1, Codec2 >, genie::compression::DeviceVarintCodec, and genie::compression::DeviceCompositeCodec< Codec1, Codec2 >.

◆ decodeArrayParallel()

__device__ const uint32_t* genie::compression::DeviceIntegerCODEC::decodeArrayParallel ( const uint32_t *  d_in,
const size_t  length,
uint32_t *  d_out,
size_t &  nvalue 
)
inline

Decompress compressed list using thread parallelism.

Node, this function should be pure virtual, but CUDA doesn't allow combination of virtual functions on both host and device.

◆ decodeArrayParallel_lengthPerBlock()

virtual __device__ __host__ int genie::compression::DeviceIntegerCODEC::decodeArrayParallel_lengthPerBlock ( )
inlinevirtual

Maximal uncompressed (or compressed) size of the array the codec is able to process

Reimplemented in genie::compression::DeviceBitPackingPrefixedCodec, genie::compression::DeviceDeltaCodec, genie::compression::DeviceCopyCodec, genie::compression::DeviceCopyMultiblockCodec, genie::compression::DeviceBitPackingCodec, genie::compression::DeviceSerialCodec< Codec1, Codec2 >, genie::compression::DeviceCompositeCodec< Codec1, Codec2 >, and genie::compression::DeviceVarintCodec.

◆ decodeArrayParallel_maxBlocks()

virtual __device__ __host__ int genie::compression::DeviceIntegerCODEC::decodeArrayParallel_maxBlocks ( )
inlinevirtual

The amount of CUDA blocks this codec is able to operate on at the same time

Reimplemented in genie::compression::DeviceBitPackingPrefixedCodec, genie::compression::DeviceDeltaCodec, genie::compression::DeviceCopyCodec, genie::compression::DeviceCopyMultiblockCodec, genie::compression::DeviceBitPackingCodec, genie::compression::DeviceSerialCodec< Codec1, Codec2 >, genie::compression::DeviceCompositeCodec< Codec1, Codec2 >, and genie::compression::DeviceVarintCodec.

◆ decodeArrayParallel_minEffectiveLength()

virtual __device__ __host__ int genie::compression::DeviceIntegerCODEC::decodeArrayParallel_minEffectiveLength ( )
inlinevirtual

Minimal effective lenth of the compression

Reimplemented in genie::compression::DeviceDeltaCodec, genie::compression::DeviceCopyCodec, genie::compression::DeviceCopyMultiblockCodec, genie::compression::DeviceBitPackingCodec, genie::compression::DeviceSerialCodec< Codec1, Codec2 >, genie::compression::DeviceCompositeCodec< Codec1, Codec2 >, and genie::compression::DeviceVarintCodec.

◆ decodeArrayParallel_threadLoad()

virtual __device__ __host__ int genie::compression::DeviceIntegerCODEC::decodeArrayParallel_threadLoad ( )
inlinevirtual

Number of decompressed values extracted by a single thread

Reimplemented in genie::compression::DeviceBitPackingPrefixedCodec, genie::compression::DeviceDeltaCodec, genie::compression::DeviceCopyCodec, genie::compression::DeviceCopyMultiblockCodec, genie::compression::DeviceBitPackingCodec, genie::compression::DeviceSerialCodec< Codec1, Codec2 >, genie::compression::DeviceCompositeCodec< Codec1, Codec2 >, and genie::compression::DeviceVarintCodec.

Definition at line 86 of file DeviceCodecs.h.

◆ decodeArrayParallel_threadsPerBlock()

virtual __device__ __host__ int genie::compression::DeviceIntegerCODEC::decodeArrayParallel_threadsPerBlock ( )
inlinevirtual

Maximal number of threads per single block

Reimplemented in genie::compression::DeviceBitPackingPrefixedCodec, genie::compression::DeviceDeltaCodec, genie::compression::DeviceCopyCodec, genie::compression::DeviceCopyMultiblockCodec, genie::compression::DeviceBitPackingCodec, genie::compression::DeviceSerialCodec< Codec1, Codec2 >, genie::compression::DeviceCompositeCodec< Codec1, Codec2 >, and genie::compression::DeviceVarintCodec.

Definition at line 82 of file DeviceCodecs.h.

◆ decodeArraySequential()

__device__ const uint32_t* genie::compression::DeviceIntegerCODEC::decodeArraySequential ( const uint32_t *  d_in,
const size_t  length,
uint32_t *  d_out,
size_t &  nvalue 
)
inline

The function must make sure not to write in d_out[nvalue] and beyond. If decompressed size is greater than the capacity (nvalue), there is no need to write any output at all.

Node, this function should be pure virtual, but CUDA doesn't allow combination of virtual functions on both host and device. If a function is pure virtual, it has to be overridden on both host and device

Definition at line 54 of file DeviceCodecs.h.

◆ encodeArray()

virtual void genie::compression::DeviceIntegerCODEC::encodeArray ( uint32_t *  in,
const size_t  length,
uint32_t *  out,

◆ name()

virtual std::string genie::compression::DeviceIntegerCODEC::name ( ) const
inlinevirtual

Reimplemented in genie::compression::DeviceBitPackingPrefixedCodec, genie::compression::DeviceDeltaCodec, genie::compression::DeviceCopyCodec, genie::compression::DeviceCopyMultiblockCodec, genie::compression::DeviceBitPackingCodec, genie::compression::DeviceSerialCodec< Codec1, Codec2 >, genie::compression::DeviceVarintCodec, and genie::compression::DeviceCompositeCodec< Codec1, Codec2 >.
