[Users] Error in exe/cactus_sim

[Rishank Diwan]

Dear Sir/Madam

I am trying to compile a Cactus executable on my laptop, which has an

ubuntu-based operating system(Ubuntu 18.04). I am using the latest version
i.e; ET_2019_10. I am using simfactory and following the Simulation Factory
Advanced Tutorial. For building, I am using generic configuration files
which are also the default files.


Here are the steps I am using:


simfactory/bin/sim setup


./simfactory/bin/sim build -j2 --thornlist ../einsteintoolkit.th


Compilation produces an executable, but when I go for running the

example file using the command,


exe/cactus_sim


I get the following error.

""

Fatal error in PMPI_Comm_rank: Invalid communicator, error stack:

PMPI_Comm_rank(110): MPI_Comm_rank(comm=0x8202540, rank=0x7ffcee11d818)

failed

PMPI_Comm_rank(68).: Invalid communicator

[unset]: write_line error; fd=-1 buf=:cmd=abort exitcode=805918213

:

system msg for write_line failure : Bad file descriptor

""


I am not able to find any relevant solution on the internet. Can you

please help me find in the solution.


Yours Sincerely,
