+!--    For the gfortran compiler the function c_sizeof produces strange erros 
+!--    which can probably be attributed to an error in the gfortran compiler.

+!--    This MPI_SENDRECV should work even with odd mixture on 32 and 64 Bit 
+!--    variables in structure particle_type (due to the calculation of par_size).
+!--    Please note, in case of 1D decomposition ( only 1 core along 
+!--    x dimension), array trlp is not allocated, leading to program crash. 
+!--    Hence, check if array is allocated and allocate it temporarily if
