Overview
Intel® Cluster Tools assist developers and managers of distributed systems to
obtain the best performance.
Intel® Trace Analyzer provides a convenient way to graphically analyze the
runtime event traces of Intel® Trace Collector, allowing developers to quickly
focus on the desired level of detail. Intel Trace Analyzer provides several
graphical displays for visualizing application runtime behavior. The timeline
and parallelism display shows per-process application activities and message
passing along a time axis. Source code location is available with the required
compiler support. Statistical displays help developers visualize the analysis of
program execution and communication operations. Most displays are available in
global and preprocess variants. The timeline view can be zoomed and scrolled.
Statistics can be restricted to arbitrary portions of the timeline display.
Graphically Analyze Runtime Event Traces
- Ease of use ? Provides a convenient way to graphically analyze
runtime event traces produced by MPI and other applications, enabling
developers to quickly focus on the desired level of detail to find
performance hotspots and bottlenecks
- Hierarchical displays ? Addresses display scalability, allowing
developers to navigate through the trace data at different levels of
abstraction (cluster, node, and process)
- Variety of graphical displays ? Provides important aspects of the
application runtime behavior in detailed and aggregate views
- Timeline views and parallelism display ? Displays application
activities, source code locations of events, and message-passing along a
time axis, allowing developers to visualize the concurrent behavior of
parallel applications, and to calculate statistics on demand for specific
time intervals and processes
- Communication statistics ? Provides communication metrics for an
arbitrary time interval and message-length distribution
- Execution statistics ? Displays subroutine execution metrics for
an arbitrary time interval and shows call-tree comparisons between different
program runs
Features and Benefits
- Display application activities and message ? passing along a time axis
to help visualize concurrent behavior of parallel applications
- Focus on the desired level of detail to identify performance hotspots
and bottlenecks
- View a hierarchical display to address display scalability
- Identify communication hotspots
- Analyze the performance of subroutines or code blocks
- Learn about communication patterns, parameters, and performance
- Evaluate load balancing
Graphical User Interface Provides Display Variants
Most displays are available in global and per-process variants. Statistics
can be restricted to arbitrary parts of the trace. Multiple traces produced by
the same application can be compared to assess optimizations. With a fast,
graphical user interface, developers can easily control displays and statistics
on large data sets by using:
- Object point-and-zoom for enhanced detail
- Context-sensitive sub-menus
- Coupled displays with automatic updates of statistics recomputation
