These options are supported on all Intel architectures.
Using the -parallel (Linux* OS) or the /Qparallel (Windows* OS) option enables parallelization for both Intel® microprocessors and non-Intel microprocessors. The resulting executable may get additional performance gain on Intel microprocessors than on non-Intel microprocessors. The parallelization can also be affected by certain options, such as /arch or /Qx (Windows) or -m or -x (Linux and Mac OS X).

Description |
|---|---|---|
-parallel |
/Qparallel |
Enables the auto-parallelizer to generate multithreaded code for loops that can be safely executed in parallel. 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-parallelization 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. |
-par-runtime-control |
/Qpar-runtime-control |
Generates code to perform run-time checks for loops that have symbolic loop bounds. If the granularity of a loop is greater than the parallelization threshold, the loop is executed in parallel. |
