Compilation error internal error: 20000_7001

[fpultar]

I have an application that is written in C++ and usually compiled using GCC/8.2.0. For a reason discussed here (https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Mix-and-match-GCC-and-Intel-OMP-problems/m-p/1365205) I would like to use the Intel toolchain instead.
"icc --version" gives me: "icc (ICC) 19.1.0.166 20191121"; operating system is CentOS 7. Bear in mind I'm on a cluster and have limited control on what I can install.

While compilation stops after some time I found that addition of the '-qoverride-limits' flag prevents premature termination. However, compilation of my code still takes very long and consumes lots of memory for translation units that involve OMP calls. Furthermore, compilation now stops at a different stage with a different error:

"[ 51%] Building CXX object src/CMakeFiles/myfile.cc.o
/cluster/project/igc/fpultar/intel-19.1.0/application/src/myfile.cc(1836) (col. 19): internal error: 20000_7001
 
compilation aborted for /cluster/project/igc/fpultar/intel-19.1.0/application/src/myfile.cc (code 4)
make[2]: *** [src/CMakeFiles/build.make:300: src/interaction/CMakeFiles/myfile.cc.o] Error 4
make[1]: *** [CMakeFiles/Makefile2:388: src/CMakeFiles/all] Error 2
make: *** [Makefile:136: all] Error 2"

 My question is, what is the internal error and how could I prevent it? I allocate 12 cores and 64 GB of memory for compilation. 

Best,

Hi,

Thank you for posting in Intel communities.

Could you please provide a sample reproducer code along with the steps you have followed? And also please let us know the version of your CentOS 7, so that we can try it from our end.

Thanks & Regards,

Madhu

Unfortunately, I cannot give you code as the project is closed source. As for the steps I have taken, I cannot tell you more than what I have posted already (Intel toolchain in the specified version, special flag '-qoverride-limits',  CentOS 7, C++11 and OMP parallelization). I opened another post with some more details on a related problem (https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Mix-and-match-GCC-and-Intel-OMP-problems/m-p/1365205) However, your system tagged it as spam and deleted it automatically. Two attempts by me to repost this information have been unfruitful.

I have searched for "internal error: 20000_7001" but could not find any information on that. I was hoping you could give me some insight on that error.

Hi,

Sorry for the inconvenience caused.

>>I'm on a cluster and have limited control on what I can install.

Could you please try compiling by installing the latest icc compiler (2021.5.0) if possible and see if you are getting the same error?

>>I cannot give you code as the project is closed source.

Please let us know if you are interested to share the sample reproducer so that we can contact you privately.

Thanks & regards,
