Abstract: Provided are techniques for lock profiling tool to identify code bottlenecks. A lock spin duration for a lock is determined. It is determined that the lock spin duration is greater than a lock trace threshold. The lock spin duration is classified into a time duration bucket. It is determining whether the lock is found in a list of locks for the time duration bucket. In response to determining that the lock is found in the list of locks, a lock count for the lock is incremented by one. In response to determining that the lock is not found in the list of locks, an entry for the lock is added in the list of locks for the time duration bucket and the lock count for the lock is initialized to one. A total spin duration time for the lock is updated by the lock spin duration.

Abstract: Provided are a computer program product, system, and method for invoking Input/Output (I/O) threads on processors to demote tracks from a cache. An Input/Output (I/O) thread, executed by a processor, processes I/O requests directed to tracks in the storage by accessing the tracks in the cache. After processing at least one I/O request, the I/O thread determines whether a number of free cache segments in the cache is below a free cache segment threshold. The I/O thread processes a demote ready list, indicating tracks eligible to demote from the cache, to demote tracks from the cache in response to determining that the number of free cache segments is below the free cache segment threshold. The I/O thread continues to process I/O requests directed to tracks from the storage stored in the cache after processing the demote ready list to demote tracks in the cache.

Abstract: Provided are a computer program product, system, and method for invoking Input/Output (I/O) threads and demote threads on processors to demote tracks from a cache. An Input/Output (I/O) thread, executed by a processor, processes I/O requests directed to tracks from the storage stored in the cache. A demote thread, executed by the processor, processes a demote ready list, indicating tracks eligible to demote from cache, to select tracks to demote from the cache to free cache segments in the cache. After processing a number of I/O requests, the I/O thread processes the demote ready list to demote tracks from the cache in response to determining that a number of free cache segments in the cache is below a free cache segment threshold.

Abstract: Processes for controlling the rate and temperature of cooling fluid through a heat exchange zone in, for example, an alkylation reactor using an ionic liquid catalyst. A cooling fluid system may be used to provide the cooling fluid which includes a chiller and a reservoir. The cooling fluid may pass from the reservoir through the heat exchange zone. A bypass line may be used to pass a portion of the cooling fluid around the heat exchange zone. The amount of cooling fluid may be adjusted, with a valve, based upon the temperature of the cooled process fluid flowing out of the heat exchange zone. Some of the cooling fluid from the chiller may be circulated back to the chiller in a chiller loop.

Abstract: In one embodiment, performance-based multi-mode task dispatching for high temperature avoidance in accordance with the present description, includes selecting processor cores as available to receive a dispatched task. Tasks are dispatched to a set of available processor cores for processing in a performance-based dispatching mode. If monitored temperature rises above a threshold temperature value, task dispatching logic switches to a thermal-based dispatching mode. If a monitored temperature falls below another threshold temperature value, dispatching logic switches back to the performance-based dispatching mode. If a monitored temperature of an individual processor core rises above a threshold temperature value, the processor core is redesignated as unavailable to receive a dispatched task. If the temperature of an individual processor core falls below another threshold temperature value, the processor core is redesignated as available to receive a dispatched task.
