threading problem

littlewang — Thu, 17 Jun 2021 02:46:23 GMT

你好，

我在使用 MLK 并行函数时遇到问题。我正在尝试将串行程序修改为并行程序，并设置 openMP 线程数=5。当我使用编译命令时

ifort ... -mkl=parallel -fopenmp

可正确设置线程数=5

但是如果我使用makefile来编译这个程序，线程数总是1。

我应该将 -mkl=parallel 添加到我的 makefile 中吗？我应该怎么办？

我把我的文件放在附件里

我很感激任何意见和想法！

hello

I'm having problems using MLK parallel functions. I am trying to change the serial program to a parallel program and set the number of OpenMP threads to 5. When I use the compile command

ifort ... - MKL = parallel - fopenmp

The number of threads can be set correctly to 5

But if I compile this program using a Makefile, the number of threads is always 1.

Should I add -mkl=parallel to my makefile? What should I do?

I put my files in the attachment

I appreciate any comments and ideas!

Hi,

Please try using the latest version of MKL, we don't support the older versions.and use the latest oneMKL Link Line Advisor tool:

Let us know if you have any issues.

Regards

Rajesh.

I'm sorry I still don't know how to deal with this problem. Here is a screenshot of the option I made in the above URL. Could you please help me modify my Makefile?

Hi,

Can you please share the Fortran compiler version, MKL version used, required files for the make, build steps. So that we can see if the issue is reproducible from our end?

Regards

Rajesh.
