Error running examples/spheres.json

[aleaj]

Hi,

I'm new to the package and was trying to first run the example of the spheres and got the following error. I write this command in the terminal: ./palace spheres.json in the folder where I have installed palace and get:

/usr/bin/mpirun -n 1 /home/aandresj/spack/opt/spack/linux-ubuntu22.04-skylake/gcc-11.4.0/palace-0.11.2-7th6eidbdqlvieu5ckwejox2g6gwpmes/bin/palace-x86_64.bin spheres.json

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

Can you help me identify what is wrong?

Many thanks and very good job with this software.

Hi @aleaj, I think I know what the issue is and how to fix it. There was a breaking change to the configuration file between v0.11 and v0.12, and it looks like you are using the spheres example config file from a recent clone of main while installing an older build of Palace with Spack (v0.11.2), causing the error.

The solution is to install Palace from the recent main, since the public Spack recipe hasn't been updated to include v0.12. You can use palace@develop in your Spack spec to do this. Alternatively you can use the Spack recipe distributed with Palace in the spack/ directory. This is I typically use as it is always up to date with the code.

Sorry for the confusion and I will submit a PR to the Spack repository to update this soon.
