[Sisc-users] DynamicEnvironment and multi-threaded apps

[Dan <gre...@ya...>]

Hi all,

I'm new to SISC and having a bit of trouble
understanding how the three big pillars of the SISC
engine (Interpreter, AppContext, DynEnv) relate.

I understand that an AppContext corresponds to a
memory image initialized from a heap file. In a
multithreaded app, all threads should share the same
AppContext (I think).

How about Interpreter and DynEnvironment ? Do I need
one of each per thread ? Do I create them upon
starting each thread and hold on to them, or only
"when needed" ? How expensive is Interpreter / DynEnv
construction ?

Regarding heap files: is there anything magic about
the default sisc.shp ? Can I save a heap file and use
it when starting SISC ?

Thanks!
Dan
