Dear kanubhav(?),
(Please name and affiliation)
MKL is a commercial product from Intel; it is searched because it is
expected to provide more or less the best efficiency. If you do not
have access to it (a campus license for example), other possibilities to
obtain optimised libraries are for example ACML from AMD (in particular
for the AMD processors - no cost), self-optimised or Ubuntu-ATLAS (I do
not know how well the pre-optimised packets from Ubuntu are),
libGOTO/GOTOBLAS, etc. If you do not provide any of those, standard,
not-really-that-optimal versions are compiled (please make sure that at
least optimal instruction set is used - for example AVX/AVX2 instructions
can benefit the speed quite much). If your serial compilation - probably
you mean one without the GPU/CUDA - worked, the standard libraries were
probably used.
The instructions how to make the configure script to find the wanted
BLAS/LAPACK libraries are in the documentation.
The problem is rather that 'nvcc' is not found - are you sure that CUDA
is installed on your machine?
Greetings,
apsi

Dear QE users
I was configuring qe-gpu 14.10.0 with espresso-5.1.2 on ubuntu 14.04
.Serial Configuration was successful, however i am getting the following

Is anything wrong? Can anyone tell me how to solve this and how to install
mkl library as i didn't find it anywhere?
