Implementations§

source§

impl CudaDevice

source

pub fn id(&self) -> i32

Cuda device ID

source

pub fn generate_and_encode_pospace( &self, seed: &PosSeed, record: &mut Record, encoded_chunks_used_output: impl ExactSizeIterator<Item = impl DerefMut<Target = bool>>, ) -> Result<(), String>

Generates and encodes PoSpace on the GPU.

This function performs the generation and encoding of PoSpace on a GPU. It uses the specified parameters to perform the computations and ensures that errors are properly handled by returning a Result type.

§Parameters
§Input
  • k: The size parameter for the table.
  • seed: A 32-byte seed used for the table generation process.
  • record: A slice of bytes (&[u8]). These records are the data on which the proof of space will be generated.
  • gpu_id: ID of the GPU to use. This parameter specifies which GPU to use for the computation.
§Output
  • source_record_chunks: A mutable vector of original data chunks of type FsFr, each 32 bytes in size.
  • parity_record_chunks: A mutable vector of parity chunks derived from the source, each 32 bytes in size.
  • proof_count: A mutable reference to the proof count. This value will be updated with the number of proofs generated.
  • chunks_scratch: A mutable vector used to store the processed chunks. This vector holds the final results after combining record chunks and proof hashes.
  • challenge_index: A mutable vector used to map the challenges to specific parts of the data.
