Syntax
TIMER <timer name or LIST>
Variable
VT_TIMER
Default
gettimeofday
Description
Intel Trace Collector can use different sources for time stamps. The availability of the different timers may depend on the actual machine configuration.
To get a full list, link an application with the Intel Trace Collector, then run it with this configuration option set to
LIST
. By setting the verbosity to
2
or higher, you get output for each node in a cluster. If initialization of a certain timer fails, no error messages are printed in this mode and the timer is specified as unavailable. To see error messages, run the program with
TIMER
set to the name of the timer that you want to use.

Product and Performance Information

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.
