[Chimera-users] Enabling multithreading in chimera

Hi Akshay,

   Chimera does not use multiple threads (with exception of a few cases 
like watching for a file system hang) and there is no way to enable 
additional multithreading.  We are interested in allowing use of 
multiple cores for specific compute intensive tasks.  What specific 
functions in Chimera do you find slow?  If the rendering is slow 
(rotating models is jerky) that is a limitation of the GPU which is 
already heavily multithreaded if you have a modern graphics card (some 
GPUs have 800 cores).
