MPIB_msgset Struct Reference
[Measurement: base data structures and functions]

List of all members.

Public Attributes

int min_size
int max_size
int stride
double max_diff
int min_stride
int max_num

Detailed Description

The message sizes for which the measurements are to be performed. Bounded by min_size and max_size. If stride > 0, message sizes are selected regularly. Otherwise, they are adaptively selected at runtime, based on the max_diff, min_stride and max_num values.

Member Data Documentation

int MPIB_msgset::min_size

Maximum message size in bytes

int MPIB_msgset::max_size

Maximum message size in bytes

int MPIB_msgset::stride

Stride in bytes for regular selection of message sizes

double MPIB_msgset::max_diff

Maximum relative difference between the result of measurement and the linear model based on the results of two previous measurements that requires further investigation. Must be non-negative, $ \le 1 $. Used in adaptive selection of message sizes.

int MPIB_msgset::min_stride

Minimum stride between message sizes. Must be positive. Used in adaptive selection of message sizes.

int MPIB_msgset::max_num

Maximum number of message sizes. Limits the number of different messages sizes the measurement is performed for. Used in adaptive selection of message sizes.
