Re: [Gems-users] What does "istcdisable" means?

[Dan Gibson <degibson@xxxxxxxx>]

Hi Mike,
Re: STCs: Simics's STCs are internal parts of Simics that interfere with Ruby's operation, so they need to be disabled before loading Ruby. The contents of the STC are flushed. 

Re: g_NUM_PROCESSORS: g_NUM_PROCESSORS is an internal Ruby parameter. Simics operates a number of processes specified by the machine definition/checkpoint. Ruby must know how many processors are in that checkpoint, and the user informs Ruby by setting g_NUM_PROCESSORS appropriately. I would not recommend setting g_NUM_PROCESSORS to a number different from the number of processors in Simics's target machine.

Hi... I'm mike

 

Using simics and gems, I have some question..

 

I saw "istcdisable" command..

For example..  simics > istcdisable

Refering related document,I have known that this mean it disable default I-Cache which be at simics and flush exiting old data.

 

So, where does these old data go???  To ruby's clean cache?? or expired ???

 

If old data is flushed to ruby's cache and ruby's cache hierarchy is different simics's default cache hierarchy, what about?

It's fine??? I thoght that if cache hierarchy of simics and ruby, it is likely to make problem.

 

Is My think right?

 

 

And another question...

Ruby use g_NUM_PROCESSORS parameter. This paramter could set the number of processor.

By the way, simics also can set the number of processor.

 

So, if the number of processor is different in two case, is it fine?

 

My qeustion is that if I use 4 processor at ruby, Do I have to set 4 processor at the front of simics???

 

Please, help me... I would appreciate your help
