Re: [Pnet-developers] How is libgc configured thread-wise in pnet? (Modified by Peter Colson)

Tum,

I'm trying to understand how the gc and it's concept of parallel 
marking relates, if at all, to the threading environment  of 
pnet/ilrun.

The gc provides for the ability to have the mark phase of it's 
operation occur in it's own thread, while the sweep phase (as I 
understand it) only ever occurs in the same thead as the alloc call. 
Parallel marking is not the default configuration for the gc.

Now, pnet/ilrun can be interpreting a number of programs at any one 
time and these would occupy their own thread or threads? If that is the 
case and one of those threads performs an alloc, then you are 
suggesting that the alloc will occur in that same thread, not in a 
parallel "marking" thread?


Regards,
Peter.
