hi all

i am trying to compile vasp on ubuntu 9.10 using ifort 11.0 compiler and same mkl library. I am able to compile serial version. But while compiling parallel version i am getting following error message

mpif90 -FR -lowercase -assume byterecl -ftz -O3 -c base.f90
f95: byterecl: No such file or directory
f951: error: unrecognized command line option "-assume"
f951: error: unrecognized command line option "-ftz"
make: *** [base.o] Error 1


what this means
is there something wrong with mpi installation

Hi there,

btw., you only need the mpif90 for the actual linking. The code is parsed to ifort anyway.

Intel changes complier options from time to time. So I'd guess you are compiling an older VASP version?
ifort (11) also checks for FORTRAN95 standards, so sometimes it is necessary to switch to the older standards (some -e95 switch or so, check the manpage).

Cheers,

alex
