__Offload_report

Controls printing offload execution time and the amount of data transferred. This function only applies to Intel® MIC Architecture.

Syntax

__Offload_report(integer)

Arguments

Name

Type

Description

integer

integer

Possible values: 1 or 2.

1 prints the offload computation time, in seconds.

2 prints the offload computation time, in seconds, and the amount of data transferred, in bytes.

Description

This API enables you to time offload regions and measure the amount of data transferred during their execution.

Using this API is equivalent to setting the environment variable OFFLOAD_REPORT.

Example

Setting __Offload_report(1) prints the offload computation time. For example:

          [FILE]            filename.c
          [LINE]            line_no
          [CPU-TIME]        0.278886
          [MIC-TIME]        0.000177

Setting __Offload_report(2) prints the offload computation time and the amount of data transferred. For example:

          [FILE]            filename.c
          [LINE]            line_no
          [CPU-TIME]        0.52
          [CPU->MIC DATA]   0
          [MIC-TIME]        0.000151
          [MIC->CPU DATA]   4
