Stefano,
If your code is working correctly in Single Threaded mode, then it is
most likely that when running in MP mode one of your threads does not have
visibility to the node in question. In order to assure that all threads
have visibility to structures you wish to share among them, the structures
should be instantiated after vgInitSys but before vgConfigSys (as vgInitSys
sets up the Shared Arenas and vgConfigSys spawns threads for app, cull,
draw, etc...). Assure that the memory allocated for the structure is being
malloc'd from the Shared arena.
In Code:
vgInitSys();
data = (MySharedData *)vgMalloc( sizeof( *data ), vgGetSharedArena() );
vgDefineSys( "Your.adf" );
Best Regards,
