Use this setting to override whether Intel Trace Collector treats the clock of all processes one the same node as synchronized or not. Whether Intel Trace Collector makes that assumption depends on the selected time source.
int VT_registerthread(int thindex)
Registers a new thread with Intel® Trace Collector under the given number.
Use the -trace-collectives or -trace-pt2pt option to reduce the trace file size or the number of Message Checker reports:
Use -trace-collectives to collect information only about Collective Operations
Use -trace-pt2pt to collect information about Point-to-Point operations
These options are only supported at runtime with the Hydra process manager.
Conceptually there is a different filter for each class of events: function events, messages and collective operations. During analysis the event is recognized when the expression is matched.
You can create a command line for analyzing specific processes with Intel® VTune™ Amplifier XE.
Go to Advanced > Command line for Amplifier XE...
You can access the context menu by right-clicking the Quantitative Timeline. Some general context menu options are common to all Charts. Quantitative Timeline provides some options that are specific to this timeline.
The View thread group influences the labels of the Sender, Receiver and Sender/Receiver groups. The View function group has no influence.
If the View shows the thread group Other, then this results in additional rows and columns for the groupings Sender, Receiver and Sender/Receiver.
Use the Filtering dialog box to specify filter expressions separately for function events, messages and collective operations under the respective tabs. You can also use the Processes tab to restrict the events to a subset of processes.
