Abstract:
Provided are a computer program product, system, and method for invoking demote threads on processors to demote tracks from a cache. A plurality of demote ready lists indicate tracks eligible to demote from the cache. In response to determining that a number of free cache segments in the cache is below a free cache segment threshold, a determination is made of a number of demote threads to invoke on processors based on the number of free cache segments and the free cache segment threshold. The determined number of demote threads are invoked to demote tracks in the cache indicated in the demote ready lists, wherein each invoked demote thread processes one of the demote ready lists to select tracks to demote from the cache to free cache segments in the cache.

Claim (Index 43):
The method of  claim 42 , wherein the I/O thread executing on one processor of the processor performs:\n allocating a cache segment; incrementing an I/O thread count in response to allocating the cache segment; determining whether the I/O thread count exceeds a run threshold; determining whether a number of free cache segments is below a free cache segment threshold in response to determining that the I/O thread count exceeds the run threshold; requesting the lock in response to determining that the number of free cache segments is below the free cache segment threshold; and demoting tracks from the demote ready list for the processor on which the I/O thread is running in response to obtaining the lock.
