  * the coupling is done one way (from MHD to MC), this brings a potential of introducing new level of parallelism (in curent code MHD and MC simulations are called one after another, sequentially)
  * the MC is in process of GPU-enabling, one may want to run both modules on different heterogenous resources (i.e. MC on GPU cluster, base MHD code on Intel Nehalem cluster)

+PIERNIK uses own build system based on Python scripts, all set of flags used for compilation are stored in plain configuration files like this one:
+{{{
+PROG      = piernik
+USE_GNUCPP = yes
+F90       = mpif90
+F90FLAGS  =  -ggdb -fdefault-real-8 -ffree-form -std=gnu -fimplicit-none -ffree-line-length-none 
+F90FLAGS += -Ofast -funroll-loops
+F90FLAGS += -I/software/local/libs/hdf5/1.8.9-pre1/gnu-4.7.2-ompi/include
+LDFLAGS   = -Wl,--as-needed -Wl,-O1 -L/software/local/libs/hdf5/1.8.9-pre1/gnu-4.7.2-ompi/lib 
+}}}
+In order to link with MUSCLE 2.0 we have to alted the last lines of the file:
+{{{
+...
+LDFLAGS   = -Wl,--as-needed -Wl,-O1 -L/software/local/libs/hdf5/1.8.9-pre1/gnu-4.7.2-ompi/lib -L/mnt/lustre/scratch/groups/plggmuscle/2.0/devel-debug/lib 
+LIBS      = -lmuscle2
+}}}
+Then we build the code with the following command:
+{{{
+# load MUSCLE
+module load muscle2/devel-debug
+# load PIERN dependencies (HDF5, OpenMPI, newest GNU compiler)
+module load plgrid/libs/hdf5/1.8.9-gnu-4.7.2-ompi
+./setup mc_collisions_test -c gnufast -d HDF5,MUSCLE,MHD_KERNEL
+}}}
