Conclusion
The current Global Computing systems are likely to work well in both LAN and WAN situations.
The use of optimized parallel library would be sufficient for vector computing servers.
In LAN, computing server performance dictates overall performance, while in WAN limitation of communication throughput is more significant. (Esp. communication-intensive applications)
We expect multiple client requests will be issued from different sites, causing “false” lowering of load ave..
The scheme which properly dispatches communication-/computation-intensive jobs to the servers is important.
