Dear VASP users,
I have seen that some of you have troubles with the parallel version of VASP compiled with the latest Intel fortran compiler.
In fact, using the standard make file for Intel fortran, both serial and parallel version have troubles !

The serial complains about difference in mixing charge density. The parallel version give completely non sens results.

One solution is to use the -O1 optimization level but this is necessary only for the following files:
#Specific options for Intel fortran compiler 10.1.11
fftmpiw.o : fftmpiw.F
$(CPP)
$(FC) -FR -lowercase -O1 -xW -I/u/fboucher/local/include/ -c $*$(SUFFIX)

fftw3d.o : fftw3d.F
$(CPP)
$(FC) -FR -lowercase -O1 -xW -I/u/fboucher/local/include/ -c $*$(SUFFIX)


You should however use the latest VASP version that is 4.6.34.
