[1] What is a distributed pool?
-------------------------------

A distributed pool is a table maintenance utility which provides
various forms of tables with arbitrary keys and data. It has been
extensively used by experimental parallel application programs. Users
can ease programming efforts by using a distributed pool.
 
The original pool provided by PIMOS operating system of PIMs did not
run in parallel. All the data is managed by a single process.
Therefore, when data are accessed from many nodes at the same time,
network congestion and access latency become problematic. The
distributed pool is designed to solve these problems. The distributed
pool distributes the original pool to each node, and maintains the
coherence among copies cached to several original pools.

The distributed pool will alleviate load congestion, and improve data
access latency. Moreover, by dispersing the memory consumption at many
transaction nodes, the maximum capacity of the pool is greatly
expanded.

[2] Execution Environment
-------------------------
Programs using a distributed pool run under PIMOS operating system of
PIMs, or KLIC a portable KL1 implementation.
