CAMB: large l segmentation fault
Posted: January 09 2008
Hi all. I am trying to run CAMB with the values l_max_scalar = l_max_tensor = 22000, but when I do I get the following output:
Age of universe/GYr = 13.823
Om_b h^2 = 0.02186
Om_c h^2 = 0.11050
Om_nu h^2 = 0.00000
Om_Lambda = 0.73294
Om_K = 0.00000
Segmentation fault (core dumped)
I have run with l_max_scalar = l_max_tensor = 11600 before with no problems so I assume this is occuring simply because of the large l value. Also, I have looked around the forum and it appears as though others have successfully run at even higher l-values so I assume it is a problem with my particular setup. Can anyone help me out with this?
I am running under Linux on a P4 2.8GHz with 1GB or RAM and I compliled CAMB using:
F90C = gfortran
FFLAGS = -O2 -I$(INCDIR) -DGFORTRAN -fno-second-underscore
