DistArray

Think globally, act locally.

DistArray provides general multidimensional NumPy-like distributed arrays to Python. It intends to bring the strengths of NumPy to data-parallel high-performance computing. DistArray has a similar API to NumPy.

DistArray is ready for real-world testing and deployment; however, the project is still evolving rapidly, and we appreciate continued input from the scientific-Python community.

DistArray is for users who

• know and love Python and NumPy,

• want to scale NumPy to larger distributed datasets,

• want to interactively play with distributed data but also

• want to run batch-oriented distributed programs;

• want an easier way to drive and coordinate existing MPI-based codes,

• have a lot of data that may already be distributed,

• want a global view (“think globally”) with local control (“act locally”),

• need to tap into existing parallel libraries like Trilinos, PETSc, or Elemental,

• want the interactivity of IPython and the performance of MPI.

DistArray is designed to work with other packages that implement the Distributed Array Protocol.
