Features
MPI Checking
- Detect deadlocks, data corruption, and errors with MPI parameters, data types, buffers, communicators, point-to-point messages, and collective operations.
- Scale to extremely large systems and detect errors among a large number of processes.
Displays
- Access a customizable, full-color interface with many detailed view options.
- Rapidly unwind the call stack and use debug information to map instruction addresses to source code.
- Set up batch runs or do interactive analyses with command lines and visual interfaces.
Scalability
- Low overhead allows random access to portions of a trace, making it suitable for analyzing large amounts of performance data.
- Thread safety allows you to trace multithreaded MPI applications for event-based tracing and non-MPI threaded applications.
Instrumentation & Tracing
- Low-intrusion instrumentation supports MPI applications with C, C++, Fortran, or OpenSHMEM.
- Automatically record performance data from parallel threads in C, C++, Fortran, and OpenSHMEM.

What Customers are Saying
"Intel Trace Analyzer and Collector for Linux helped to drastically improve the performance of RIKEN's molecular dynamics cluster software. We were able to shorten MPI communication time by half by finding and removing bottlenecks with nonblocking communication patterns. Since Intel Trace Analyzer and Collector can embed instrumentation into the program, we can tell the execution time of each function and its load balance, which enabled us to very easily understand where to optimize. Intel® MPI Library and Intel® Cluster Tools provide us the best cluster development environment."
—Dr. Takhiro Koishi, RIKEN
"Our FEKO* electromagnetics code runs on various parallel environments (for example, clusters of different sizes, shared memory machines) and utilizes complex numerical algorithms that are nontrivial to parallelize. Intel Trace Analyzer and Collector has proven to be a very valuable tool to help understand FEKO parallel communication patterns, and consequently in optimizing the message-passing call that results in an extremely well-performing electromagnetics ISV cluster application."
—Dr. Ing Ulrich Jakobus, technical director, EM Software & Systems
