### checkpoint files not getting created

Hi,

burn_in = X sets the number of user defined burn in steps that are done before any samples are recorded in your chains directory. It basically tells the program to throw away X samples before putting any samples in output chains. When running MPI the program still has its own routines that check when true burn in of the chains has completed.

### Re: checkpoint files not getting created

Hi,

I am running cosmomc-May2020 on workstation.The chains are stopped after 15 days.I have set convergence stop to 0.01.
When I am rerunninng the chains, I have got invalid check points error.
Here is the output:-

Code: Select all

BK15_dust data param indices:          49          50          51          52          53          54          55          56          57          58          59          60          61          62          63          64

Fast divided into            3  blocks
Block breaks at:           15          35
54 parameters ( 7 slow ( 0 semi-slow), 47 fast ( 0 semi-fast))
invalid checkpoint files
application called MPI_Abort(MPI_COMM_WORLD, 128) - process 3

I will be grateful if you can kindly let me know how can I solve this problem.

Are you re-running with the same number of chains and exactly the same parameters?
