fpe0 and mpi_init fails

dr_jfloyd — Tue, 30 Jan 2024 19:40:58 GMT

Cross-posting from the Fortran forum:

Have a large mpi application (cfd model) where we use fpe0 when running our verification suite in debug. After updating to the current OneAPI compilers, using either ifort or ifx the following program fails at MPI_INIT if fpe0 is used as a compiler option. This means no verificaiton cases can be run in debug, as they all require intializing MPI (the actual application uses MPI_INIT_THREAD but that also fails). The error message follows the source code.

program test_mpi
use mpi_f08
implicit none

@dr_jfloyd

I tested your code and it compiles / runs fine.

Can you please post your full compilation/link line and the execution command?

Best

@TobiasK

Thank you for taking the time to look at this.

Compile:

% mpiifx -fpe0 test_mpi.f90

Run:

% mpiexec -n 2 ./a.out

Compile:

% mpiifort -diag-disable=10448 -fpe0 test_mpi.f90

Run:

% mpiexec -n 2 ./a.out

Without -fpe0 these run. Our system is running RHEL 9.3.

@dr_jfloyd

Can you please run with:

export I_MPI_DEBUG=10

export I_MPI_FABRICS=shm

If that works, please also run with

export I_MPI_FABRICS=shm:ofi FI_PROVIDER=psm3

Both worked with the test program.

Using the full application running on the head node both worked.

Trying the full application on the compute nodes (InfiniBand):

-Option 1)

--worked as long as I kept the core count to one node.

--did not work over multiple nodes and gives the following (line 89 is the call to MPI_INIT_THREAD)

-Option 2) did not work either way

Error is below. The underlined lines repeated mulitple times.

@dr_jfloyd

Can you please try with:

export I_MPI_FABRICS=shm:ofi FI_PROVIDER=psm3 ?

I am still not able to reproduce this issue.

Can you please provide the output of lscpu?

I did try "export I_MPI_FABRICS=shm:ofi FI_PROVIDER=psm3". That was the option 2) result in my prior post. But since had some success with just the shm, I felt you had pointed me in the right direction. I started playing with various options and just now had success with both:

export I_MPI_FABRICS=shm:ofi FI_PROVIDER=verbs

and

export I_MPI_FABRICS=shm:ofa FI_PROVIDER=verbs

Thanks for all the help!
