CosmoMC: why this error "MCMC.f90: Couldn't start after 1000 tries"

Use of Healpix, camb, CLASS, cosmomc, compilers, etc.

CosmoMC: why this error \"MCMC.f90: Couldn''t start aft

Post by Jie Ren » May 16 2006

I had compiled the cfitsio, healpix, wmap3, camb, and cosmomc successfully. When I ran cosmomc using the default parameters (./cosmomc params.ini, without modifiying any files), an error occured after more than one hour: "MCMC.f90: Couldn't start after 1000 tries - check starting ranges". Thanks for any help.
