 ====== COSMOMC at CHPC ======
+From its [[http://cosmologist.info/cosmomc/|website]]: "CosmoMC is a Fortran-based Markov-Chain Monte-Carlo (MCMC) engine for exploring cosmological parameter space, together with Fortran and python code for analysing Monte-Carlo samples and importance sampling (plus a suite of scripts for building grids of runs, plotting and presenting results). It can also be compiled as a generic sampler without using any cosmology codes."

 ===== Compiling COSMOMC =====
+NB! COSMOMC is currently being tested on the new cluster. The most recent version currently able to successfully compile (with CFITSIO-3.37.2 and CLIK-1.0) is February 2015.
+Paths to ''CFITSIO'' and ''PLC'' (CLIK) can be found under ''/apps/chpc/astro/utils/intel/v16-openmpi188/'', along with that for ''GSL'' if required.
+The Intel 2016 modules to add to your environment are ''chpc/parallel_studio_xe/16.0.1/2016.1.150'' and ''chpc/openmpi/1.8.8/intel-16.0.1''
+My ''.bashrc'' file is equipped with the following:
+<code bash>
+export cfitsio=/apps/chpc/astro/utils/intel/v16-openmpi188/cfitsio-3.37.2-build
+export PLANCKLIKE=cliklike
+export CLIKPATH=/apps/chpc/astro/utils/intel/v16-openmpi188/plc-1.0
+export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CLIKPATH/lib
+export LD_LIBRARY_PATH=/apps/chpc/astro/utils/intel/v16-openmpi188/cfitsio-3.37.2-build/lib:$LD_LIBRARY_PATH
