[Gems-users] Question about some terminologies

["Ju-Young Jung" <juyoung.jung@xxxxxxxxx>]

Hi, all.

I have questions about some terminologies.

In ruby, what does a node mean? From my debugging trace using MOSI_SMP_bcast protocol , I guess it simply means "processor+cache" excluding directory controller. Is it correct? If it is the case, can a directory controller also be a node? Moreover, can all machines defined in *.sm be treated as a node?

 

Next, I want to get more concrete understanding for the difference between an ext_node and int_node in file specified network topology; this queustion is related to how to write user-defined topology file. Could you let me know about it?

 

As another queustion, I would like to know how many PerfectSwitches will be instantiated when I am going to use MOSI_SMP_bcast protocol with dual processors. Is Node-to-PerfectSwitch the one-to-one?

 

Lastly, Topology class has a member function "makeLink( )", and it has an assert statement ensuring not to connect two end-point nodes directly together. Will commenting in this assert, and connecting two nodes directly cause some unexpected problems?

 

 

Thanks for your response in advance.

 

 

 

Best Regards,
