Multi-threaded support for LUA

["Vivek Gupta" <vivek.gupta@...>]

Hi,

 

I have a multi-threaded application in ‘C’ which invokes LUA functions. Because of the fact that LUA is a single threaded language I have used a global LUA state and used a mutex to serialize the access to global LUA state among the multiple threads. But this implementation has a performance bottleneck because of this serialization aspect.

 

To get rid of this serialization, is it feasible to maintain LUA state on a per thread basis? But I can foresee some issues with the LUA global. We might require synchronizing these LUA global variables. Has anyone tried this out? Some practical example would really help.

 

With regards,
