HPXLA: A HPX Linear Algebra Library

To-Do:

---

• Switchable assertions/exceptions
• Add policy template parameter to matrix classes
• Convert local BLAS functions to accept matrix classes with arbitrary policies

Building

---

HPXLA depends on HPX, ensure you have a recent hpx build installed to some location. If you don't wish to install HPX into your system you can simply set the flag CMAKE_INSTALL_PREFIX to the location of where you'll be building hpx (e.g. /home/example/build is hpx will be built to that folder) while following the hpx install tutorial.

You'll also need either BLAS or CBLAS, the easiest way to obtain either is via atlas.

Linux

1. clone the master HPXLA git repository

   git clone http://github.com/STEllAR-GROUP/hpxla.git

2. create a build directory. HPXLA should be an out-of-tree build

   mkdir hpxla_build
   cd hpxla_build
   

3. Invoke CMake, note that you'll likely need to specify the same compiler used to build HPX

   cmake -DCMAKE_CXX_COMPILER=/usr/bin/compiler \
          -DHPX_ROOT=/path/to/hpxbuild           \
          /path/to/hpxla/source
   

   e.g.

   cmake -DCMAKE_CXX_COMPILER=/usr/bin/g++  \
          -DHPX_ROOT=/home/dev/hpx_build     \
          ../hpxla
   

4. Make to build all targets

   make
