Houston, we have a problem

[Jianwei Li]

I think I was wrong after a careful look at the standard output.

operation    header I/O time    data I/O time
write 2: 	1.250E-01 	0.000E+00
read 2:  	6.250E-02 	0.000E+00

It seems that Nfmpi_Put_Vara_Float_All/Nfmpi_Get_Vara_Float_All
are not running properly in this case.

We should look in more details for problems ...
