Member Data Documentation

◆ bucketMarkers

int* _CudaRequest::bucketMarkers

index in the cell or particle list for the cells/particles for a given bucket

◆ bucketSizes

int* _CudaRequest::bucketSizes

number of particles in a bucket on the GPU

◆ bucketStarts

int* _CudaRequest::bucketStarts

index in the particle array on the GPU of the bucket

◆ cb

void* _CudaRequest::cb

Callback

◆ fperiod

cudatype _CudaRequest::fperiod

Size of periodic volume

◆ numBucketsPlusOne

int _CudaRequest::numBucketsPlusOne

Number of buckets affected by this request

◆ numInteractions

int _CudaRequest::numInteractions

Total number of interactions in this request

◆ state

void* _CudaRequest::state

Pointer to state of walk that created this request

◆ stream
