This approach suffers from reducing the amount of latent parallelism available, which will possibly impact the speedup observed in practice For situations where the input data size is very large, all individual invo cations of ma p cost roughly the same, however, this approach should not tangibly impact the parallel efficiency (and should improve things)

When loops are nested, there is an interesting decision to make Considering a two-loop case, should we parallelize the outer loop, the inner loop, or both

Finally, the type of operation on the tickets (sold or cancelled) is stored: messagesetstring("type", After this, the message is published: tPublisherpublish(message); And everything is closed:

As with most things, there isn' t a simple one size fits all answer In many cases, parallelizing the outer loop will yield the most benefit This assumes that, in the above example, N is sufficiently large to expose enough paral lelism to achieve a speedup If N is less than the number of processors, for instance, then it is worth considering an alternative such as parallelizing the inner loop instead Again, this assumes M is sufficiently large If it isn't, then it may be worth at considering parallelizing both (When it comes to the parallelization process, we can use the techniques we have already reviewed ) A word of caution: a naive implementation of nested invoca tions of the above parallel loop examples will lead to terrible performance because the growth for units of work will be quadratic (Le, O(NM , and recursion and blocking will become a problem for many implementations (such as the thread pool, where such a scheme could easily lead to dead lock) There are alternative approaches One can "fuse" the inner with the outer loop, and then parallelize the single remaining loop This exposes more information to the parallel loops implementation, so that it can more accurately partition the entire space of the iteration at once, rather than dynamically

This is typically the best approach for such blatant nesting It also leads to roughly the same cache access patterns as if the inner loop remained sequential It is also worth considering whether to rearrange the loop's structure If the data access pattern of the body is such that parallelizing on the inner loop but executing the outer loop inside each thread will lead to better

On March 3, 2009, we read a story entitled On Pentagon Waste: Just Give It to Us Straight Often, Bureaucracy-Speak Masks the Real Story, by Anna Mulrine [15] Her story was interesting because she focused on the phraseology of Washington bureaucrats who are simply not straight talkers Sometimes it can be hard to get the point through the Washington bureaucratese She tells the story wonderfully and we quote her
