coarray giving mpd error

Hello,

I am just trying to learn coarray. The code, from Steve Blair-Chappell's is:

$ cat hello.f90 

!This is file : hello

Program  hello

Implicit None

write(*,*)"Hello", this_image()

End Program  hello

and compiled it using

 ifort -coarray hello.f90

But I am getting error:

$ ./a.out 

mpdallexit: cannot connect to local mpd (/tmp/mpd2.console_rudra_ICAF_2735); possible causes:

1. no mpd is running on this host

2. an mpd is running but was started without a "console" (-n option)

The error is correct, as there is no mpd running.
But do I really need mpi to run coarray?
my fortran is :

$ ifort -vifort version 13.1.3
