### Cosmomc Instalation and Running

Posted:

**February 10 2009**Dear All

I've installed Cosmomc in my computer. In the final steps of the instalation, I had to do:

1)>./camb params.ini – and results are:

Age of universe/Gyr = 13,592

…...........................................

Doing the above command, I didn't get any error.

But, when I write

.>cosmomc params.ini

or

.>cosmomc params.ini 1

Random seeds: 23978, 26009 rand_inst: 0

Computing tensors: F

Doing CMB lensing: T

lmax = 2100

Number of C_ls = 3

Varying 7 parameters ( 0 fast)

Initializing WMAP likelihood, version v3

So, I used the suggestion in cosmomcofee.info/viewtopic.php?t=1074, i.e. , ulimit -s unlimited and the program starts run and show the following

0 rat: 0.3875969 in 1032 (M) best: 1329.441

…..............................

Is this normal?

I would like to Know the amount of time required to run the algorithm?
