Here is a Friday post that has a sufficient lack of information that will probably be impossible to answer. I have some older Fortran code I'm trying to improve the performance of.
Hi, I'm alayzing my openmp program using Intel vtune 2016. I used the -fopenmp flag when compiling and it runs on a 4-core machine.
I'm just wondering why should we use TBB instead of OpenMP in HPC aplications? Is there any specific featrue(s) that separate this libraray from OpenMP?
I am trying to compile simple code using openmp.
Here is the code (file test.cpp):
A knowledgeable customer asked why there is no OpenMP min or max reduction for C, as there is for Fortran. I agreed this seems useful.
i want to use OpenMP lib in Xcode with intel compiler, but when i use "#include <omp.h>" it show me "'omp.h' file not found".
I tried to get an OpenMP 4.0 test case to run where the code calls a user library that is compiled for host and mic (-mmic)
I have a program - call it A - that makes heavy use of OpenMP. I see the CPU time going down as I increase the number of threads in my "#pragma omp for" loops.
I have a program where at one point I call a function.
