  "Fully resolved simulation (FRS) of finite size particles in  
                       convecting fluids"
                       
We briefly review methods available for FRS of particle laden flows; 
including specific features, applicability and computational 
efficiency. The fictitious domain method for immersed rigid bodies 
[1], and our multi-grid solution technique for the incompressible 
Navier-Stokes will be discussed in detail. We show the key ideas of 
algorithm optimizations specific to many-core hardware (i.e. 
graphics processors) and modern parallel programming paradigms. 
Finally, we analyze not so dilute particle laden flows in a 
lid-driven cavity for various Reynolds numbers and particle Reynolds 
numbers.
