qopt-for-throughput, Qopt-for-throughput

Determines how the compiler optimizes for throughput depending on whether the program is to run in single-job or multi-job mode. This feature is only available for ifx.

Syntax

Linux:

-qopt-for-throughput=value

Windows:

/Qopt-for-throughput:value

Arguments

value

Is one of the values "multi-job" or "single-job".

Default

OFF

If this option is not specified, the compiler will not optimize for throughput performance.

Description

This option determines whether throughput performance optimization occurs for a program that is run as a single job or one that is run in a multiple job environment.

The memory optimizations for a single job versus multiple jobs can be tuned in different ways by the compiler. For example, the cost model for loop tiling and prefetching are different for a single job versus multiple jobs. When a single job is running, more memory is available and the tunings will be different.

IDE Equivalent
