We present a novel architecture for distributed computing in a peer-to-peer network.
In particular, we realize the Paderborn University BSP-based Web Computing Library
(PUBWCL), which formerly used a centralized client-server architecture for scheduling
and load balancing, as a pure peer-to-peer system. Using distributed heterogeneous hash
tables (DHHT), our architecture features scheduling and load balancing of tightly
coupled, massively parallel algorithms in the bulk-synchronous (BSP) style with a
minimal number of migrations.

Furthermore, our architecture is capable of heterogeneous BSP programs whereas the
former version of PUBWCL could only handle homogeneous BSP programs.
