Supporting adaptive shared cache management

A method comprising:

• determining, by a processing device, a cache line to evict from a shared cache;
• selecting, by the processing device, an inactive processing core of a plurality of processing cores associated with the shared cache;
• transmitting, by the processing device, a private cache of the inactive processing core, a message to initiate a prefetch of the cache line by the private cache of the inactive processing core;
• and
• forwarding, by the processing device, the cache line from the shared cache to the private cache.

A system comprising:

• a shared cache to store a plurality of cache lines;
• and
• a processing device, operatively coupled to the shared cache, to:
• determine a cache line to evict from a shared cache;
• select an inactive processing core of a plurality of processing cores associated with the shared cache;
• transmit, to a private cache of the inactive processing core, a message to initiate a prefetch of the cache line by the private cache of the inactive processing core;
• and
• forward the cache line from the shared cache to the private cache.
