cells_per_block_shmem()

__host__ constexpr unsigned int CUDAWrappers::cells_per_block_shmem ( int  dim, int  fe_degree  )

constexpr

Definition at line 704 of file cuda_matrix_free.h.

Variable Documentation

block_size

constexpr int CUDAWrappers::block_size = 512

constexpr

Define the size of a block when launching a CUDA kernel. This number can be changed depending on the architecture the code is running on.

Definition at line 29 of file cuda_size.h.

chunk_size

constexpr int CUDAWrappers::chunk_size = 1

constexpr

Define the size of chunk of data worked on by a thread. This number can be changed depending on the architecture the code is running on.

Definition at line 35 of file cuda_size.h.

warp_size

constexpr int CUDAWrappers::warp_size = 32

constexpr

Define the number of threads in a warp.

Definition at line 40 of file cuda_size.h.

mf_max_elem_degree

constexpr unsigned int CUDAWrappers::mf_max_elem_degree = 10

constexpr

Define the largest finite element degree that can be solved using CUDAWrappers::MatrixFree. Changing this number will affect the amount of constant memory being used.

Definition at line 47 of file cuda_size.h.

mf_n_concurrent_objects

constexpr unsigned int CUDAWrappers::mf_n_concurrent_objects = 5

constexpr

Define the maximum number of valid CUDAWrappers::MatrixFree object. Changing this number will affect the amount of constant memory being used.

Definition at line 53 of file cuda_size.h.
