Syntax
SYNC-PERIOD <duration>
Variable
VT_SYNC_PERIOD
Default
-1 seconds
=
disabled
Description
If clock synchronization through message exchanges is enabled (the default), then Intel Trace Collector can be told to do message exchanges during the application run automatically. By default, this is disabled and needs to be enabled by setting this option to a positive time value.
The message exchange is done by a background thread and thus needs a means of communication, which can execute in parallel to the application's communication, therefore it is not supported by the normal MPI tracing library
libVT

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.
