rangular_mpi Eorror in '...': free(): invalid next size (fast):$

[JonnoDean]

Hello,
I am having an issue with trying to run the rangular_mpi program on my University's local HPC. I receive this error:

rangular_mpi Eorror in '...': free(): invalid next size (fast):$

I'm not sure what this means, or what to do.

Any suggestions would be greatly welcomed. Thank you.

Hi @JonnoDean!

Hmm not sure, never seen this. I suppose it has to do with your MPI implementation/system setup. Maybe first make sure that everything really compiles well, without any errors (I suppose you did that already), then also check that you compile everything with e.g. gcc and/or ifort or whatever you use. I.e. make sure that e.g. mpifort --version gives GCC if you use gfortran. Sorry, with this limited amount of info I don't think I can help more. Maybe first make sure you can install the codes on a non-HPC machine and try them like that first? And, do. the codes work in serial (non-MPI)?

Hi @jongrumer

Thank you so much for your quick reply! I've also sent a question to our HPC team so hopefully they know... I've made sure it compiles well, and other calculations run perfectly, it's just this one that has run in to some difficulty!

If I find out the answer, I'll let you know in case a similar question gets asked in the future.

Best,
Jonno
