Most the time you will adjust the topic as you progress, so unless your
supervisor is very strict, you can try one thing which will give you
bigger picture and the you will know better.

If you are into computing and programming, then exploring/implementing
high-performance algorithms: 2 things coming to mind are 1. domain
decomposition and distributed memory parallelism (MPI), 2. DEM on
OpenCL/CUDA chips. Both of them might be very nice topic for a PhD, the
first would entail work on yade itself, the second probably a separate
code. DEM on OpenCL is a work that's probably never been done (OpenCL is
no older than 1 year), if that matters.
