Dear VTune users,
I have a requirement to run VTune to run in attach mode and i use the command
I'm now using Intel VTune Amplifier XE 2015. Also, I have no problem in running Tachyon (sample code).
Currently, I'm running analysis on the executable file generated from the compilation of C source code.
Discover how to use Intel® Parallel Studio to tune hybrid applications by reviewing MPI utilization inefficiencies and balancing thread load levels.
Profiling my codes, I observed some curiously large overhead and spin time, which covered almost 100% of the CPU usage bar. I use Vtune 2013 and 2015.
I'm trying to get wait time and wait count data from some openmp applications, but it return always zero when using locksandwaits or N/A using the concurrency option.
I'm using Intel VTune to analyze my parallel application.
Does VTune support OMPT APIs for OpenMP performance analysis?
Intel OpenMP Runtime Lib. supports OMPT APIs.
