Dear OPAL-Team,

I wanted to simulate using
    mpirun -np 2 opal input.in

The simulation "opal input.in" runs perfectly fine without errors, but using mpirun shows multiple error messages over and over again and the results look 'strangely merged'(?; don't know how to call it; I've put two pictures in the attachement).

Here are some main error messages (the step number changes)

    [proc 0] E: H5WriteStepAttribString: Cannot overwrite attribute /Step#0/OPAL_flavour
    Error> H5 rc= -2 in /home/frieders/opal/opal_source/git-OPAL-src/src/Structure/H5PartWrapperForPT.cpp @ line 326
    [proc 0] E: H5WriteStepAttribFloat64: Cannot overwrite attribute /Step#0/SPOS
    ...

    [proc 0] E: H5SetStep: Cannot query link //Step#346.
    ...

    [proc 0] E: H5WriteStepAttribFloat64: Iteration is invalid! Have you set the time step?
    Error> H5 rc= -2 in /home/frieders/opal/opal_source/git-OPAL-src/src/Structure/H5PartWrapperForPT.cpp @ line 375

I've saved the complete terminal output here:

I guess the error occurs because I've done something wrong when compiling OPAL
(either within needed toolchain or within the making of OPAL; I have used the "OPAL-2.4" branch with commit ffded40c6dd317d).

I guess it has something to do with h5hut. Do you have any hint for me, where to look for? Can I test h5hut by itself?

(Until now I've only used a virtual machine using Debian 10, but now I've a desktop-pc with Ubuntu 20.04.1 LTS at hand, where the error occurs too.)

Best regards and thank you very much in advance

Simon
