Now, i just start researching BlueBDM. so I refer to and quote site1(applications), site2(ISCA15_Sang-Woo_Jun), site3(studylib).
BlueDBM : An Appliance for Big Data Analytics
- BlueDBM is a system architecture to accelerate Big Data analytics.
in site1(applications), just BlueDBM show remote environment and hardware structure.
the image below is hardeware of blueDBM
in 5.3 Software interface of hardware at above paper
you have a doubt of Connectal.
from now on, I am looking for Connectal framwork
