BICEP likelihoods for Cosmomc
Dear Antony,
I was running Planck likelihoods with Cosmomc, one before the last update.
Now I want to try with Bicep2 one, so can I ask for repository account.
And where I can get the more details on running?
Best,
Gansukh Tumurtushaa

you can email if you need a repository account, though Bicep likelihood is also in the March 2014 version. See readme files and sample .ini files for help.

BICEP likelihoods for Cosmomc
I have been trying to reproduce following figure:

with the latest CosmoMC version, March2014. I think I can produce green contours with the use of PLA chain. But I do not know how to plot others with Bicep2 data.
I know the bicep2 data set is provided in /data/BICEP but how one can use them to plot the figure showed in a link above?
Thank you.

BICEP likelihoods for Cosmomc
I have compiled the "test.ini" file (the latest cosmomc) with action=0 using following command:
And, it took about 54 hours. Is it usual? Everything was in default form.
After changing the test.ini file little bit, it's compiling over 54 hours by now. I wonder whether everything is going okay or not. Is it usual?
Code: Select all
mpirun -np 8 ./cosmomc test.ini

Re: BICEP likelihoods for Cosmomc
A standard test run for me goes in about 6 hours to good convergence (R<0.1), and 24 hour to excellent convergence (R~0.01), using 4 cores per chain on fairly modern computer (I usually run 4 chains on one 16 core node, 4 cores per chain).
On a cluster you should usually edit the job_script file as appropriate for your machine, and if necessary the submitJob function in python/jobQueue.py, and then run
(I just updated this bit of the readme, it was out of date)
Make sure your run is using openmp correctly, e.g. each chain process is actually using the number of cores it should be using (if you are not using openmp then it will be slower walltime but slightly more efficient use of computer resources).
