When you profile your software with VTune™ Amplifier XE you often start from looking at the top function hotspots list. This allows you to see what functions are spending CPU resources, so you can focus your optimization efforts.
Function call counts can provide some additional information to . . .

When parallel applications have to initialize their data from file as their input or write result data to file as their output, when not optimized, the data read/write can become a limiting factor for the multi-threaded ...

It is known that the Windows Store apps API is missing some commonly used thread functions, such as function CreateThread() and those that work with TLS keys. This is yet another great opportunity to move your application development from thread-based parallelism to task-based parallelism. This ...

Hi everyone
I need help for a problem that bothers me several days.
When I use only OpenMP, the code works fine, the time for 4 threads is 70s and 136s for 8 threads.
However, when I use MPI+OpenMP, I found the code did not spped up, i.e. the time for threads=1 and 8 are the same!!!
I am using ...

Hi,
I found that function names appear as is in the release binaries if a OpenMP loop has been defined inside.
Moreover, paths from the build machine and code line numbers are also indicated.
For example, using FORTRAN compiler 10.0.025 in an executable I've got:
;D:\cygwin\home\build\dev\tags\ ...

Regarding performance, assuming we get a block of data that will be freqenctly accessed by each threads, and these data are read-only, which means threads wont do anything besides reading the data, then is it benefitial to create one copy of these data (assuming the data there read-only, and the ...
