Re: Spatial model in MADlib (GWR)

Hi Rahul

Thanks for your reply. Should I build MADlib and Postgres with
enable-debug and no optimization flags? How can I list source code of
MADlib in GDB ? Sorry for asking such silly questions.

Best,
Chenliang Wang

 Hi, Frank

 Recently,I am just looking at the detail of development guide and trying
 to complete the serial algorithm. And I plan to implement GWR dividing
 the loop into pieces of chunks executed in several nodes. However, I am
 not sure if there are some specials details need to be designed for
 distributed models in GPDB because I haven't developed model in MPP
 architecture. I hope this distributed manner would be implemented
>> easily.

Hi Chengliang

There's some information on debugging
​in ​
our old wiki page

​. There's no example there but the process is simple once you have the
server process id.
