joshThe simulation environment should be setup to evaluate provisional designs with respect to a variety of test conditions & overall goodness metrics. It may turn out that some good designs require a backward compatibility mode to work with current system OS & provide extra benefits with an OS that is informed about how to optimize their usage.

joshIntuitively – the OS/firmware/design should manage –
writes go to fastest cache memory first, & then get shifted to their long term location
reads that are frequent and/or chunked should be striped in the manner of multi-raid
infrequent/stale data can be powered down until needed
might be some extra gain in smart prediction – hard to say, depending on other factors – some sequences of reads will be common.

joshI’m imagining that most of the work on lock-free algorithms for work queues can be mapped to designs that are not corrupted by sudden power loss.

Below the top of the stack, there was a replacement for a complaining witness to replacement who was treated badly in error environment. Unknown results.
