ICPC compiler core dump mcpcom

Good Afternoon

I have been running into an issue when compiling using the 2020 parallel studio XE.
I am compiling the SLATE libraries. There is no issue with the configuration of the Intel compilers and including and linking MKL
However, during some of the build steps, I encounter

": internal error: ** The compiler has encountered an unexpected problem.
** Segmentation violation signal raised. **
Access violation or stack overflow. Please contact Intel Support for assistance.

icpc: error #10105: /opt/intel/compilers_and_libraries_2020.0.166/linux/bin/intel64/mcpcom: core dumped
icpc: warning #10102: unknown signal(1440094384)
icpc: error #10106: Fatal error in /opt/intel/compilers_and_libraries_2020.0.166/linux/bin/intel64/mcpcom, terminated by unknown

which halts the compilation. I removed the optimization flags based on some much older threads I saw but this didn't seem to help. I believe all the includes are correct and I was able to compile using gcc. Linking is also fine but should be irrelevant at this stage. 

Any assistance would be appreciated. I can provide OS and PATH's if needed.

Hi Nicholas,

Could you let us know the following details:

  • OS that you have used.
  • SLATE library repository that you have used.
  • Steps that you have followed, leading to the error.

Hi Rahul 

Thanks for your help.

I am running on Ubuntu 18.04.4 LTS but I briefly tried on my Ubuntu 16 machine as well to check and had a similar issue. 
I am working the with the public repository https://bitbucket.org/icl/slate

Process to error
source intel Parallel (source {$INTEL_ISNTALL}/parallel_studio_xe_2020/bin/psxevars.sh)
cd to slate (cd ${SLATE_SRC_DIR})
cd to blaspp sub dir (cd blaspp)
make configuration  (make config CXX=icpc blas=mkl)
make blaspp (make lib -j) 
cd to lapackpp (cd ../lapackpp)
make configuration  (make config CXX=icpc blas=mkl)
make lapackpp (make lib -j)
go to slate root (cd ..)
create following make.inc with configuration

CXX    = mpiicpc    # C++ compiler
FC     = ifort  # Fortran compiler (optional)
openmp = 1         # Enable OpenMP
mpi    = 1         # Enable MPI 
mkl   = 1         # Use MKL 
cuda_arch =   # One or more of: kepler maxwell pascal volta turing (empty to deconfigure GPU)

then make (make)

a few objects will build followed by the error

": internal error: ** The compiler has encountered an unexpected problem.
** Segmentation violation signal raised. **
Access violation or stack overflow. Please contact Intel Support for assistance.

icpc: error #10105: /opt/intel/compilers_and_libraries_2020.0.166/linux/bin/intel64/mcpcom: core dumped
icpc: warning #10102: unknown signal(-277112656)
icpc: error #10106: Fatal error in /opt/intel/compilers_and_libraries_2020.0.166/linux/bin/intel64/mcpcom, terminated by unknown


Thanks for any tips. Its possible I am missing a flag or something.

Hi Nicholas,

Do you have the required dependencies to manually build the SLATE library? 

And also I've noticed the source path for sourcing "psxevars.sh" as $INTEL_ISNTALL (could be a typo). 

Meanwhile, we are trying to build the SLATE libraries manually and will let you know once its done.

Hi Nicholas,

We are able to reproduce this error when we tried to build the "slate" library with icpc. We will let the concerned engineering team know about this issue. Thanks for reporting this issue.

Hi Rahul

Thank you for the quick response. I'd be interested in any updates or resolutions that may be found. I can work with GNU in the meantime but I'd prefer to use Intel once this issue is resolved for certain clusters.

Thanks again

Hi Nick, Can you look into one of the objects that failed to compile, then replace -c with -E and provide us the output along with your command line options?

Hi 

Thanks for the quick response. 

I changed the rule in the makefile for CC files from -c to -E and it seems like objects are all building fine but now I get a linker error during the library link step.  I'll post again if I get the full library built with the tests or if the error crops up again.

What is the difference between the -c and -E options? I am very much an end-user so some of these things elude me.

-E is to create a preprocess file. I don't need the entire project to be built with -E.

Can you look into your log file, then just select only one source file which failed to compile, then replace -c with -E.

ex: icc -O2 -axAVX -ipo foo.c -c =>  icc -O2 -axAVX -ipo foo.c -E >& foo.i

Thanks for clarifying the misunderstanding. 

I ran the make to error which occurs at 
icpc     -O1 -std=c++11 -fPIC -fopenmp -DSLATE_NO_CUDA -I./blaspp/include -I./lapackpp/include -I./include -I./src -c src/internal/internal_her2k.cc -o src/internal/internal_her2k.o

I replaced the -c with -E and have attached the resulting object. 

Thanks again

I was able to compile your preprocess file.

orcsle147:/tmp/vah1$ icpc     -O1 -std=c++11 -fPIC -fopenmp -DSLATE_NO_CUDA test_internal_her2k.i -w -c -V
Intel(R) C++ Intel(R) 64 Compiler for applications running on Intel(R) 64, Version 19.1.0.166 Build 2019112

orcsle147:/tmp/vah1$gcc -v

gcc version 8.1.0

 

Can you please see if you are able to compile the attached file using the same command options on your system?

Maybe I should try reinstalling Parallel Studio?

I found a system with Ubunto 18 and was able to reproduce it. Previously, I compiled on RHEL7 and it worked.
