Multiple Hardware Fabrics

• Get high-performance interconnects, including InfiniBand*, Myrinet*, as well as TCP, shared memory, and others

• Efficiently work through the Direct Access Programming Library (DAPL), making it easy for you to test and run applications on a variety of network fabrics.

Streamlined Product Setup

• Get users up and running faster with the ability to install under root or through an ordinary user ID

• Use the provided mpivars.sh and mpivars.csh shell scripts for easy environment setup.

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 as well as non-MPI threaded applications.

Simplified Process Management

• Reduce hand-coding work by using the mpirun script, which automates multiprocessing daemon (MPD) startup and cleanup

• Take advantage of flexible system-, user-, and session-specific configuration files

• Give the end user a reliable runtime with transparent support for fallback Internet Protocol (IP) interfaces
