Next, you can hide threads that are not performing any work in the scenario of interest by selecting their names from the column at the left and then clicking theHide Selected Threadsicon in the toolbar. Such threads can exist for many reasons. For example, they may be idle thread pool t...
This obviates the need for fine-grain, per-object locking, as well as the need for a thread-safe, concurrent garbage collector. This is significant when you factor in how Python's scoping works at a language level: Python code executing in a parallel thread can freely access any non-local...
When there are no available idle threads, the runtime creates a new thread. When the body of a parallel loop occasionally blocks, this mechanism helps maximize the overall task throughput. However, when many iterations block, the runtime may create many threads to run the additional work. ...

Most of the popular work on parallel models of computation have their basis on the concept of threads. Threads are a seemingly straightforward adaption of the dominate sequential model of computation in concurrent systems. However, as Ed. Lee stated in his paper "The Problem with Threads", "...
This means that concurrent processing is restricted to the number of input partitions. The advantage of ordered processing mode, is that for an assignment of 1000 partitions to a single consumer, you do not need to run 1000 consumer instances or threads, to process the partitions in parallel. ...
For mutual exclusion, only one of a number of contending concurrent activities at a time 27 The Landscape of Parallel Computing Research: A View From Berkeley should be allowed to update some shared mutable state, but typically, the order does not matter. For producer-consumer synchronization, a...
7.3.3 Event-based Notification Mechanisms for Concurrent Query Processing. There are two ways an application can detect completed requests in the Completion Queue. One is polling, where the function returns immediately regardless of whether there are any entries in the Completion Queue. The other is...
Aggregated error messages - Debug friendly with full visibility: Having trouble debugging in concurrent environment? Not any more! All exceptions, timeout, stack traces, request sent and response received time arecaptured and aggregatedin theresponsemap. It is available inParallelTaskfor polling right...
The Nx simultaneous encoders could be implemented using simultaneous (concurrent) software threads or simultaneous (concurrent) hardware blocks.In many data centers, servers are not fully loaded (utilized), and thus concurrent software threads are usually available. Thus multiple encoded blocks of the ...
