Thank you all.
Here's my story. I'm physics student and my master degree work is
"Application of GPU on DFT calculations". I need this BigDFT to run
certain
examples on cuda based GPU computer and on regular CPU and discuss the
results.
Cygwin was my first choice because i felt comfortable using it. But I
think
this is gonna be harder then i expected. I guees i should give up
Cygwin and
instal (maybe) UBUNTU on partition of my computer and try there. Any
suggestion there?
Thank you all again, you've been most kind.
I am most of the way through building bigdft under cygwin. I have
no idea how the GPU aspect might work but here is what I've done
so far:
1) Download blas.tgz to ~/downloads (where I put things)
In ~/tools (because I like it):
tar xzvf ~/downloads/blas.tgz
In ~/tools/BLAS:
Edit make.inc as desired
make
cp blas_LINUX.a /usr/lib/libblas.a
2) Download lapack-3.4.2.tgz to ~/downloads
In ~/tools, tar xzvf ~/downloads/lapack-3.4.2.tgz
In ~/tools/lapack-3.4.2:
cp make.inc.example make.inc
Edit make.inc as desired; note that libblas.a is in /usr/lib, so
you *must* edit that line
make [takes a LONG time]
cp *.a /usr/lib
1 & 2 are already available on liblapack-devel
$ cygcheck -l liblapack-devel |grep "\.a"
/usr/lib/libblas.a
/usr/lib/libblas.dll.a
/usr/lib/liblapack.a
/usr/lib/liblapack.dll.a
/usr/lib/libtmglib.a
3) Download bigdft-1.6.0.tar.gz to ~/downloads
In ~/tools, gunzip -c ~/downloads/bigdft-1.6.0.tar.gz | tar xvf -
In ~/tools/bigdft-1.6.0:
./configure (takes a while)
make (takes quite a while)
This ultimately failed when linking, so something seems missing or
slightly off. I will try to look at it later.
On the other hand, setting up a Linux partition, or using
a Linux virtual machine under Windows, are reasonable options too.
