          Which version of oneAPI are you using to build pytorch? I am using oneAPI binaries from https://www.intel.com/content/www/us/en/developer/articles/tool/pytorch-prerequisites-for-intel-gpu/2-5.html and I am getting linking errors:

Looking at CMakeFiles/torch_cpu.rsp I see that mkl_core_dll.lib is used for linking and it doesn't define these i_* symbols.

@xuhancn , could you help refine the title of this issue? As we synced offline, it should not be related xpu.

@EikanWang EikanWang removed the module: xpu Intel XPU related issues label Oct 29, 2024

turn off USE_MIMALLOC_ON_MKL temporary. (pytorch#139204)
9c925ae 
Fixes pytorch#138994

We can turn off `USE_MIMALLOC_ON_MKL` temporary. Due to it caused pytorch#138994

For totally fixed, we need fix `USE_STATIC_MKL` lost functionality issue: pytorch#138996, and then get the correctly MKL linking type(shared/static). It still need some time to pass all CI and builder scripts.
