P3:Personal Power Plant
Makes over your PCs into power generators on the Grid
P2P Resource Transfer and Aggregation
for Distributed Computation
P3 is middleware for high-performance distributed computing that makes effective use of
existing PCs. It enables engineers and scientists to harvest PC’s compute power in their
organization. It also enables contributors on Internet to participate in research projects
involving too massive compute power for a single organization to provide. Unlike
conventional distributed computing projects, in P3 a “participant” is not only a “ resource
provider” but also a “resource user” because a participant both provides and uses the power.
Quick and Ad-hoc Aggregation of Heterogeneous
and Volatile PCs on intra- and Internet
Quick and ad-hoc aggregation
- Easy installation through web browse
- Automatic update of the middleware
- PCs can join and leave dynamically
LAN and Internet
- P3 detects false calculation results from
possibly malicious PCs on Internet
- Firewall traversable job/PC discovery and
parallel processing
Heterogeneous PCs
- Different kinds of OSes work together
Easy development of application programs
- A programmer has to know only several
classes and methods

P2P Concepts
P3 utilizes JXTA, a widely accepted P2P library. P2P
concepts efficiently support P3:
Discovery: PCs dynamically discover each other
and jobs without a centralized server
Peer Group: PCs are grouped into job peer groups,
in which PCs carry out code distribution, job control,
and group communication for parallel computation
Overlay: Enables end-to-end communication over
NAT and firewall. It supports parallel processing in the
message passing model

Generation Software Development”.

P2P Middleware for Transfer and Aggregation of
PC Computational Resources
P3 is middleware used for distributed computing that makes effective use of existing PCs. It
enables engineers and scientists to harvest PC’s compute power of existing computers in their
organization. It also enables outside contributors to participate in research projects that are too
massive for a single organization to handle. Unlike conventional distributed computing projects, in
P3 a “participant” means not only a “resource provider” but also a “resource user” because the
participant both provides and uses the power.

Discovery: PCs dynamically discover each other and jobs
without a centralized server.
Peer Group: PCs are grouped into job peer groups, where

Overlay Network: Enables end-to-end communication
over NAT and firewall. It supports parallel processing in the
message passing model.

Future Plans
Integration of harnessed PCs into other kinds of Grid
resources such as PC clusters and DBs. (in 6-18 months)
Commercial dealings of collected resources. (in 2-5
years)
