Hi,

I'm a PhD student at Uppsala University working on heterogeneous multicore programming, and only recently found out about StarPU. Obviously, I'm quite keen on seeing what it can do and what I can do with it, so I've tried to get it running on a system with a quad-core Intel i7 920 and an Nvidia GPU. I've tried both the downloadable version 0.4 and the SVN trunk, with a variety of configuration options, but the hello_world program dies.

The assert STARPU_ASSERT(n == 1) fails in load_bus_latency_file_content() on line 679. I've done a little investigation, and can say that the sampling file "latency.hostname" has 100 elements and the function reads them all perfectly. But STARPU_MAXNODES is set to 13 in common/config.h. When I changed it to 10, then hello_world works, and so do the rest of the basic_examples.

So I guess I'm writing mainly to inform you that this was my experience and perhaps you could look at it. There doesn't seem to be a ./configure option to set the STARPU_MAXNODES, and I haven't seen any instructions in your documentation about this, so maybe I'm doing something wrong. Anything you can say to enlighten me would be greatly appreciated.

Thanks and regards,
Marcus Holm
