Testing the OpenMP Synchronization Code

After you have added OpenMP synchronization code (such as locks, critical sections, or atomic operations), but before adding the constructs that cause the program to use parallel execution, you should test your serial program. The synchronization code may introduce problems if you have inadvertently used a non-recursive mutex in a recursive context, or if your edits accidentally changed some other piece of program behavior.
It is much easier to find these problems in the serial version of your program than it will be in the parallel version.

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
