[Starpu-devel] Getting StarPU running

[Marcus Holm <marcus.holm@it.uu.se>]

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
