The Intel® Trace Analyzer and Collector employs the use of the Structured Trace File Format (STF) in order to profile MPI applications in a scalable and efficient manner.
I have established secure shell (SSH) connectivity on my cluster where each node has a public key. However, when I use any secure shell utility on the cluster, I am still prompted for a password. What am I doing wrong?
This Beta release of the Intel® Parallel Studio XE 2016 introduces a major change to the 'Named-user' licensing scheme (provided as default for the 2016 Beta licenses). Read below for more details on this new functionality as well as a list of special exceptions. Following a thorough Beta testing period, implementation will carry forward into the product release.
The What's New pages describe features and changes since the last release.
The Release Notes include important information, such as:
Intel® Trace Collector library libVT.a contains entry points for all MPI routines. They have to be linked with your application object files before MPI library of your system. Intel® Trace Collector requires a set of additional libraries. For your convenience the itacvars scripts set the environment variables $VT_ADD_LIBS and $VT_LIB_DIR accordingly.
On Linux* OS, the Intel® Trace Collector can sample hardware counters with the Performance Application Programming Interface (PAPI). Because PAPI might not be available on a system, support for it is provided as an additional layer on top of the normal Intel® Trace Collector.
This layer is implemented in the VT_sample.c source file. It is a sample file that traces counters available through PAPI High level API.
To record hardware counters, do the following:
The application has to bootstrap the communication between the VTserver and its clients. This is done as follows:
The application server initiates its processes.
Each process calls VT_clientinit().
VT_clientinit() allocates a port for TCP/IP communication with the VTserver or other clients and generates a string which identifies the machine and this port.
