If I understand it correctly something like:
range.filter!(...).map!(...)
browse range 2 times, one for filter and one for mapping doesn't it?
Is there a way to "parallelize" this kind of operations?
std.parallelism has lots of cool features to help with range
parallelization. Here is map:
http://dlang.org/phobos/std_parallelism.html#.TaskPool.map
There are some examples of mine at
http://ddili.org/ders/d.en/parallelism.html
Here is an excerpt from the Summary section at that link:
- parallel() executes the iterations of foreach loops in parallel.
- asyncBuf() iterates the elements of an InputRange semi-eagerly in
parallel.
- map() calls functions with the elements of an InputRange semi-eagerly
in parallel.
- amap() calls functions with the elements of a RandomAccessRange
fully-eagerly in parallel.
- reduce() makes calculations over the elements of a RandomAccessRange
in parallel.
