The John von Neumann Institute for Computing (NIC) has
aproved our project proposal for the JUQUEEN supercomputer at the
Forschungszentrum Jülich. Together with the STEllAR group we will work
on Auto-tuned Large-scale Simulations on BG/Q with
LibGeoDecomp and HPX.
That's the project's title. It consists of three
- Single Node Optimizations: verctorization of kernels and
adaptation to the hardware threading scheme on Blue Gene/Q.
- Scaling of HPX on BG/Q: interfacing HPX' parcel ports with the
native communication infrastructure of BG/Q; process placement.
- Auto-tuning for LibGeoDecomp: automatic adaptation of
model-specific parameters to optimize running time. (Yes, Knuth would
find an analytic formula for each and every parameter. Auto-tuning is
just more time-efficient in terms of developer time.
