disable KMP_AFFINITY for AMD ryzen
If you want to disable KMP_AFFINITY for AMD Ryzen, you can do so by setting the environment variable KMP_AFFINITY
to disabled
. This can be done in a few different ways depending on your operating system and the programming language you are using.
Here's an example of how to disable KMP_AFFINITY for AMD Ryzen in C++ using OpenMP:
cpp#include <cstdlib>
#include <omp.h>
int main()
{
// Disable KMP_AFFINITY
std::putenv("KMP_AFFINITY=disabled");
// Enable OpenMP parallelism
#pragma omp parallel
{
// Do something in parallel
}
return 0;
}
In this example, we use the std::putenv()
function to set the KMP_AFFINITY
environment variable to disabled
. We then enable OpenMP parallelism using the #pragma omp parallel
directive.
Note that the specific method for setting environment variables may vary depending on your operating system and programming language. In general, you can set environment variables using the appropriate function or command for your system.
