首先,我们需要导入Python中的multiprocessing和numpy库。 importmultiprocessingimportnumpyasnp 1. 2. multiprocessing库用于创建和管理进程。 numpy用于高效地处理数组。 2. 创建共享数组 使用multiprocessing.Array来创建共享数组。 # 创建一个可以存储100个浮点数的共享数组shared_array=multiprocessing.Array('d',100) 1....

We deployedElasticsearch6.4 as a single node with max heap size set at 32 GB and 6 physical cores running on Debian 9.6. Using Python’s multiprocessing pool we initiate 12 indexing instances with a bulk-size of 3,500 documents each. These numbers were assigned empirically based on the collec...

A great breakdown of threading versus multiprocessing, and influential for some of the work I’m doing. How to Make Python Wait This one actually reignited my interest in figuring out how to use threading. It’s a good explanation of the different approaches to make a script wait in Python...
There are various techniques for obtaining the result of a work function, such as passing a queue to the function, or subclassing threading.Thread, but we’re not going discuss them any further, because the multiprocessing package provides a better method for using pools, and the concurrent....
