system call intrinsics not working when using ILP64 version of Intel MPI

Hi,

I am using Intel MPI 5.1.2 and ifort version 16.0.1 under linux.  I have a code that uses the 'system' intrinsic to perform some file/directory manipulations that no longer works properly when using the latest version of parallel studio (it works with earlier versions). Attached is a very simple test case that illustrates the problem by attempting to create a directory either using the 'system' function of the 'execute_command_line" function.  Basically, when using the standard 4-byte mpi interface there are no issues.  However, when using the 8-byte ILP64 mpi interface, the system call fails silently and the execute_command_line function crashes the program.  Also attached is a screen shot of the test case command line run on my system.

Another issue I notice with the mpi included in the latest parallel studio is that I keep getting an 'undefined symbol: MPI_F_STATUSES_IGNORE' warning when running the test case with the ILP64 interface.  The ldd output is also shown in the screen shot.  If I perform an

                         nm /PATH/TO/libmpi_ilp64.so.4 | grep STATUSES_IGNORE

                         132:                 U MPI_F_STATUSES_IGNORE

I see that the symbol exists in the library but that it is undefined.

I'm going to move this to the Clustering (MPI) forum. I don't see that it's a Fortran issue. I'll note that on Linux, EXECUTE_COMMAND_LINE just calls system.

Hi,

I was just wondering if anybody had a chance to look at the issue described above.

Thanks,

It seems like this is still an issue. I have been encountering this condition this week under the use of Intel MPI 5.1.3 and ifort 16.0.3 under Linux.

Has this issue been addressed?

I'm seeing the same issue in Intel MPI 5.1.3.

Thanks,

Rob

Hi,

  I used the older versions (MPI and compiler versions ) pretty close to the ones you used but I could reproduce the issue. Can you provide the exact commands that you used to compile and run the attached a.f90? Sorry, the screenshot has rather small font

correction to the previous post: I meant "could NOT reproduce"

After little bit more tweaking, I think I was able to reproduce the issue with these commands:

-bash-4.2$ mpiifort -i8 -o test-ilp64.x test-ilp64.f90

-bash-4.2$ mpirun -ilp64 -n 1 ./test-ilp64.x

 

Is that how you were running your example?

 

Thanks

Mark

Hi Mark,

-bash-4.2$ mpirun -ilp64 -n 1 ./test-ilp64.x

Yes, that is how I was compiling and running the program. 

Thanks,

John,

   I talked to engineering - they asked my to submit an internal ticket (I intend to do it). I do not have the time estimate for the resolution although at this point.

If you have Intel Premier Support (IPS) account - you could submit this too through IPS - this way you can track the issue directly.   

Thanks,

Mark

This still seems to be an open issue. Any ideas on when it will be fixed?

Let me check. What version (of Intel MPI) do you use now? Can you use the latest 2017 Update 2?

Please check the latest Intel MPI. Issue is fixed since 2018 Update 3.
