Subject: [9fans] parallel systems
Date: Thu, 29 Oct 2009 06:08:23 +1100 [thread overview]
Message-ID: <20091028190823.GA2378@nipl.net> (raw)
I think my main points were good.
* can parallelize by duplicating subsystems / divide and conquer
* can parallelize by pipelining, even down to the arithmetic level
* latency is limited by Ahmdal's law, potential throughput should not be
* multi-tasking can potentially use close to the full power of a system
A factory is a parallel system. A car factory can come close to fully
utilizing thousands of human and robot workers.
I think well-designed parallel systems can efficiently solve many laborious
computing problems. Invocations of Ahmdal have not convinced me otherwise.
