Building PyACTS
Can we build a general Python-base user interface
to the some of the functionality available in the
ACTS Collection? (see next slide)

Building PyACTS

• Q. Why PyACTS?
• Python is open source and follows this model for
  development, and it has great acceptability among
  computational scientists. And ACTS tools are now
  being widely used by computational scientists
  because they are "freeware", robust, portable and
  high-performing.

Performance Evaluation I

• Performance Evaluation of Numerical Algorithms
• (ScaLAPACK, PETSc, SuperLU, Hypre, TAO, OPT)
• Perform some test on one or a set of these tools
  in the millennium cluster at UCB, and other
  supercomputers (like the NERSC IBM system). Can
  we write some recommendations to the tool
  developers? Can we make provide some useful
  feedback to users of these tools? Can we compare
  this to other available software in the market
  (robustness of the implementation, performance)?

5
Performance Evaluation II

• Another project may involved the study of
  different data distribution and layouts using
  tools under ACTS
• (Global Arrays, PETSc, ScaLAPACK, Hypre)
• As before, can we write some recommendations to
  the tool developers? Can we make provide some
  useful feedback to users of these tools?

6
Performance Evaluation III

• Performance Evaluation of Scientific Application
• ACTS has a small collection of scientific
  applications that can benefit from the use of the
  ACTS tools. One project could involved the study
  of the performance of the application before and
  after the application is prototype with the use
  of ACTS tools.

The Customized Option
Do you have a scientific problem and are
looking for computational solutions? Let us help
you start prototyping your code using the
applicable tools under ACTS. At the end you will
have a high performing code, learned about the
ACTS Collection and completed your final project
requirement!
