thanks a lot, I have been using the following flags
export F77=ifort
export FFLAGS="-O3 -xT -funroll-loops"
export CC="icc"
export CFLAGS="-O2 -xT -mieee-fp"
export CXX="icpc"
export CXXFLAGS="-w -O2 -xT -mieee-fp"
export CPP="icc -E"
export CXXPP="icpc -E"
export BLAS_LIBS="-L/opt/intel/Compiler/11.1/072/mkl/lib/em64t/
-I/opt/intel/Compiler/11.1/072/include/ -lmkl_intel_lp64 -lmkl_sequential
-lmkl_core -lpthread"
./configure --prefix=$HOME/myoctave3352 --disable-extra-warning-flags
--disable-docs
At first, it seems to work better, but I am now facing compilation failure
with message
./.libs/liboctinterp.so: undefined reference to `__builtin_isfinite'
./.libs/liboctinterp.so: undefined reference to `__builtin_isnan'
./.libs/liboctinterp.so: undefined reference to `__builtin_isinf'
>From what I saw on intel forums, I have the impression that it is a bug from
icc and icpc.
Anyway, that is not a big deal as the performances are already very good
using the following combination gcc + g++ + ifort + mkl.
Thanks anyway !
J.
