[boinc_dev] Simple cuda aplication.

[Francisco Sanz García]

Hello everibody.

This is my first message to the list.

I'm trying to develop a simple cuda application, the product of two
matrices, it works fine in standalone mode, but when I
try to run it following the instructions of
http://boinc.berkeley.edu/trac/wiki/AppDebug, I obtain the following:

I think that my client_state_save.xml is fine:
