Searching for HPX-Application to generate work on multiple Nodes

[leonfse]

Hello, I am looking for an open source HPX-Application, which I can use to generate work on multiple Nodes, in order to analyse the performance of said application.

Any ideas, suggestions and experiences are very welcome,
Leon

Any hpx + cuda + multiple nodes example?

Any hpx + cuda + multiple nodes example?

HPX distributed work and CUDA are orthogonal and unrelated. You should be able to combine these two easily.

For me HPX without any other Libraries would be most fitting.
Can any of the Examples in this GitHub Repository put multiple Nodes to work?

@leonfse I suppose the 1D stencil examples in examples/1d_stencil would be one (simple) option. I think starting from 1d_stencil_5 they are distributed. https://github.com/STEllAR-GROUP/tutorials/tree/master/examples/03_stencil also contains a 2D stencil example, although it may need some tweaking to make it work again with the latest version of HPX.

@msimberg Thank you very much for the hint! 1d_stencil_5 did not work on two haswell nodes for me, but 1d_stencil_8 did.

Yes, 1d_stencil_8 is what you want to play with. I'll have a look at 1d_stencil_5 to see what's wrong.
