I tried to compile ABACUS from source, and I used the latest OneAPI toolchain, but it always strangely compiles well then has numerical problems running. ( file `abacus` also appears to be working properly, but none of the results are reproducible tests in `tests/integrate`.)

I would like to know if the community has a complete test of the compilation toolchain?

BTW, I wonder if this is related to #2299

Hi @saltball ,

Could you please provide more details on it? Like, how many processes you use and how the results deviate. Thanks.

For the Intel OneAPI toolchain, due to limited resources, we ensure the correctness of compiling without further running full test suite in CI process linked with each PR.
We internally host a nightly test on both GNU toolchain and Intel toolchain (report here). @pxlxingliang Does the nightly test verifies if the results are correct?

Hi, Chun Cai,The daily test will check if the running is normal ending, but it will not check the numerical results like energy or force.

Thanks for the reply, I'll try to give details using some of the full environments as much as I can, but I may need a few days.

Thanks for waiting, just to make sure I'm not raising an issue that's already been resolved, I compile with a fresh container and latest code(93090d). I tested oneAPI 2023 and 2022, and found that I didn't have any more problems not matching up on the machine where I had problems with my previous tests. However, by running . /Autotest.sh, I still get the following tests with error: (Sometimes there are more errors, but those appear to be numerical deviations)

The previous problem of this issue I met doesn't exist anymore, I think this issue cloud be closed.

BTW: oneAPI 2023 prints icpc: remark #10441: The Intel(R) C++ Compiler Classic (ICC) is deprecated and will be removed from product release in the second half of 2023. The Intel(R) oneAPI DPC++/C++ Compiler (ICX) is the recommended compiler moving forward. Please transition to use this compiler. Use '-diag-disable=10441' to disable this message., but I guess that is not a problem.
