  This paper presents the first complete, integrated and end-to-end solution
for ad hoc cloud computing environments. Ad hoc clouds harvest resources from
existing sporadically available, non-exclusive (i.e. primarily used for some
other purpose) and unreliable infrastructures. In this paper we discuss the
problems ad hoc cloud computing solves and outline our architecture which is
based on BOINC.
