Recompile debian's hpcc with other libs

To contact us Click HERE
I installed hpcc using apt-get, but -- and this is a first -- when trying to run it complained over missing libs.

---

Why compile?

hpcc

hpcc: error while loading shared libraries: libatlas.so.3gf: cannot open shared object file: No such file or directory

Doing
aptitude show hpcc 

Depends: libatlas3gf-base, libc6 (>= 2.7), libopenmpi1.3, mpi-default-bin

apt-cache search libatlas.so.3gf

libatlas3-base - Automatically Tuned Linear Algebra Software, generic shared
libatlas3gf-base - Transitional package to libatlas3-base

and doing aptitude search atlas|grep ^i

i   libatlas-dev                    - Automatically Tuned Linear Algebra Softwar
i A libatlas3gf-base                - Transitional package to libatlas3-base

but
locate libatlas.so.3gf
comes up empty.

So build your own:
sudo mkdir /opt/hpcc
sudo chown $USER /opt/hpcc
cd /opt/hpcc
wget http://ftp.de.debian.org/debian/pool/main/h/hpcc/hpcc_1.4.1.orig.tar.gz
tar xvf hpcc_1.4.1.orig.tar.gz
cd hpcc-1.4.1/
wget http://ftp.de.debian.org/debian/pool/main/h/hpcc/hpcc_1.4.1-2.debian.tar.gz
tar xvf hpcc_1.4.1-2.debian.tar.gz
patch -i debian/patches/add-Make.Debian.patch

Edit Make.Debian. For some reason LAdir is ignored, hence the -L option in LAlib

The above assumes that you've compiled your own openblas as shown elsewhere on this blog. You can use whatever math libs you want. Again, there are a couple described on this blog (acml, netlib blas/lapack, openblas, ATLAS). I've had success with the netlib blas/lapack and atlas (built with netlib lapack).

mv Make.Debian hpl/
make arch=Debian

Hopefully everything went well. Now you need an input file.
cp _hpccinf.txt hpccinf.txt

Edit hpccinf.txt:

Launch by doing
mpirun -n X ./hpcc
where X=Ps times Qs (e.g. 3 in the example above).

I put the hpccinf.txt in a shared (nfs) folder (~/jobs), created a file called myhost

tantalum slots=2 max_slots=4
boron slots=2 max_slots=6
neon slots=2 max_slots=8

 and then launched using
mpirun -n 4 -hostfile myhost /opt/hpcc/hpcc-1.4.1/./hpcc
