PetscStreamType

Stream blocking mode, indicates how a stream implementation will interact with the default NULL stream, which is usually blocking.

Synopsis

#include <petscdevicetypes.h> 
typedef enum {
  PETSC_STREAM_GLOBAL_BLOCKING,
  PETSC_STREAM_DEFAULT_BLOCKING,
  PETSC_STREAM_GLOBAL_NONBLOCKING,
  PETSC_STREAM_MAX
} PetscStreamType;

Values

• PETSC_STREAM_GLOBAL_BLOCKING - Alias for NULL stream. Any stream of this type will block the host for all other streams to finish work before starting its operations.

• PETSC_STREAM_DEFAULT_BLOCKING - Stream will act independent of other streams, but will still be blocked by actions on the NULL stream.

• PETSC_STREAM_GLOBAL_NONBLOCKING - Stream is truly asynchronous, and is blocked by nothing, not even the NULL stream.

• PETSC_STREAM_MAX - Always 1 greater than the largest PetscStreamType, do not use
