Auto-Parallelization Options Quick Reference

These options are supported on IA-32, Intel® 64, and IA-64 architectures.

Linux* and Mac OS* X

Windows*

Description

-parallel

/Qparallel

Enables the auto-parallelizer to generate multithreaded code for loops that can be safely executed in parallel.

IA-64 architecture only:

Depending on the program and level of parallelization desired, you might need to set the KMP_STACKSIZE environment variable to an appropriately large size.

-par-threshold(n}

/Qpar-threshold[:n]

Sets a threshold for the auto of loops based on the probability of profitable execution of the loop in parallel; valid values of n can be 0 to 100.

-par-schedule-keyword

/Qpar-schedule-keyword

Specifies the scheduling algorithm or a tuning method for loop iterations. It specifies how iterations are to be divided among the threads of the team.

-par-report

/Qpar-report

Controls the diagnostic levels in the auto-parallelizer optimizer.
