Compiling and running CAMB using NAGf95: floating underflow

Posted: November 23 2005

Hello everyone,

I compile and run CAMB using NAGf95 with the flags specified in the Makefile. When the code runs, it produces the following message:
"Warning: Floating underflow occurred"
I tried adding the -r8 option, but it doesn't have any effect and the -double option results in compilation errors in inidriver.F90. Does anyone know how to avoid this underflow?
