Configurable Prefetching Level

[ashwin153]

Prefetching increases the conflict window. The earlier you get a key, the more likely it is that the key might be changed before the program finishes executing. In some applications, particularly when running in memory, it may be beneficial to delay prefetching a key as long as possible. It should be possible to configure the prefetching level in the runtime.

• EAGER: Prefetch as early as possible. Default.
• LAZY: Do not prefetch.
