CosmoMC: Error in halofit, CAMB error

Post by Jiping Dai » March 25 2019

Hello everyone,

I have modified the evolution equations in both background and perturbation with CosmoMC-Jun2016. But an error occurs when running MCMC (after a while),

Error in halofit
CAMB error
MpiStop: 7
application called MPI_Abort(MPI_COMM_WORLD, -752432896) - process 7

Is there any way to solve this trouble?
Thank you in advances.

Hi Jiping,
Have you tested the halofit module after you made the modifications?
I guess the error might be caused by some unsatisfied conditions during the calculations.

Also look at a more recent cosmomc version.
