Is there any expectation about release time frame? I am working (and i am hoping to reasonable resolution) to push a new installment of small optimizer enhancements for distributed algebra.
it would help me to know if there's a sense of release time frame, it'd give me an idea what to shoot for. I want to offer few small things that we mostly already discussed. (1) optimizer techniques to detect unary elementwise operations such as drmX * drmX dexp(drmX), mexp(mxX), vexp(vec) (in R simply exp(x)) mxX ::= abs _ ( i.e sparse/dense elementwise evals) (2) better binds like 1 cbind drmX, drmX cbind 1 (enhancement relevant for "playing with shell" things) (3) smaller things like non-int keyed matrices to int-keyed matrix converstion with old 2 new key extraction (4) various bug fixes (5) whatever i forgot Nothing earth shuttering but even small things are difficult (but not unprecedented) to contribute here. -d
