Java 8 "automatically-parallelizable bulk-data operations"

[Piotr Bzdyl]

This is my first post to this list so "Hello" to everyone!


As you can see below, I was trying to find out what bulk operations would
be automatically parallelizable in Java 8 (as stated by JSR-337 in the
Performance section). I was forwarded to lambda mailing list as the
development is being done by lambda project group.

Could anybody shed some light on this topic? I checked the lambda/lambda
source code but couldn't find any parallel implementation of those bulk
operations.

Best regards,
Piotr
