Subject [jira] Commented: (HAMA-244) Consider more simplified BSP programming interface
Date Thu, 13 May 2010 10:20:42 GMT


Chanwit Kaewkasi commented on HAMA-244:

It seems now there are some rooms for me to tackle simplification.
Considering this, it would be possible to have a declarative wrapper for BSP to help people
easier to adopt it.
Probably a DSL like, 

def bsp = bsp(config: HAMA) {
    jobName = "BSP test job"
    inputPath = "/abcd"
    outputPath = "/abcd"
    inputFormat = MyInputFormat
    outputFormat = MyOutputFormat
    carriage = BSPProgram    

would do the job.

> Perhaps, every BSP program will be consists of three steps such as,  initialization,
 SPMD code implementation, and finalization from developer angle.
> However, currently there is no interface layer so users have to do all the works w/o
any guide.
> Would be nice if it allow to use a more simplified interface.
