Member Data Documentation

structSize

size_t shafft_1d_config_t::structSize

Must be sizeof(shafft_1d_config_t).

apiVersion

int shafft_1d_config_t::apiVersion

API version (set by init).

globalSize

size_t shafft_1d_config_t::globalSize

Global FFT length.

precision

shafft_t shafft_1d_config_t::precision

SHAFFT_C2C or SHAFFT_Z2Z.

initial

shafft_1d_layout_t shafft_1d_config_t::initial

Layout before execution.

output

shafft_1d_layout_t shafft_1d_config_t::output

Post-forward layout.

allocElements

size_t shafft_1d_config_t::allocElements

Required buffer size in complex elements.

isActive

int shafft_1d_config_t::isActive

Boolean.

activeRank

int shafft_1d_config_t::activeRank

Rank within active subset; -1 if inactive.

activeSize

int shafft_1d_config_t::activeSize

Number of active ranks; 0 before resolve.

worldComm

MPI_Comm shafft_1d_config_t::worldComm

Dup of communicator passed to init.

activeComm

MPI_Comm shafft_1d_config_t::activeComm

Subcommunicator of active ranks; MPI_COMM_NULL if inactive.

nodeId

int shafft_1d_config_t::nodeId

Node identifier.

nodeCount

int shafft_1d_config_t::nodeCount

Total number of distinct nodes.

hostname

char* shafft_1d_config_t::hostname

Config-owned.

hostnameLen

size_t shafft_1d_config_t::hostnameLen

Length of hostname.

deviceName

char* shafft_1d_config_t::deviceName

Config-owned; NULL if not applicable.

deviceNameLen

size_t shafft_1d_config_t::deviceNameLen

Length of deviceName.

flags

int shafft_1d_config_t::flags

Bitwise OR of shafft_config_flags_t values.

status

int shafft_1d_config_t::status

Last resolve/init status code.

reserved

int shafft_1d_config_t::reserved[8]

Reserved for future use.
