I'm really looking forward to use 4.1, but now it's time to upgrade one of my production application to use 4.0.10.
I've been forming up the Hama project with Edward Yoon.
He's been doing the really great job of getting matrix computation work over Map/Reduce pattern. Now we are planning to have a MATLAB-like environment for them.
Here's a number of issues:
- The language needs to support lazy evaluation,
for re-arragement of a numerical expression to properly pick the right algorithm before computation.
I love Groovy, so it's time to develop the Groovy-derived langauge that suites numerical computing.
- Support BigDecimal, BigInteger by default.
Yep, we're again looking on large-scale computation, and sometime it's beyond the integer's boundary.
So we need the built-in support for these kinds of data type.
- Matrix and Vector to be the first class elements. For example,
def a = [1 2 3] // this is going to be a Vector
def b = [1 2 3; 4 5 6; 7 8 9] // this is going to be a matrix
def a = [1, 2, 3] // this is going to be an ArrayList
def a = [a:"a"] // this is going to be a HashMap
