Running error in CosmoMC

Post by Saisandri Saini » July 18 2023

I am trying to run Cosmomc May 2020 version with modecode and I am getting the following run time error using both test.in as well as test_planck.ini.

Code: Select all

===================================================================================
=   BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES

===================================================================================
YOUR APPLICATION TERMINATED WITH THE EXIT STRING: Killed (signal 9)
This typically refers to a problem with your application.

After running cosmomc_debug I am getting the following output.

Code: Select all

Number of MPI processes:           1
 Error :Ini_Open, file not found: 
 MpiStop:            0
application called MPI_Abort(MPI_COMM_WORLD, 21923) - process 0
[unset]: write_line error; fd=-1 buf=:cmd=abort exitcode=21923
:
system msg for write_line failure : Bad file descriptor
I will be grateful if this could be resolved.

Regards,

If Ini_Open is failing presumably the ini file or path is wrong

Hello Sir,
Thank You for your help. I am running cosmomc on my workstation. It is running four chains at a time. The chains run for half an hour and then it stops and shows the following error:
