Techniques for configuring a hypervisor scheduler to make use of cache topology of processors and physical memory distances between NUMA nodes when making scheduling decisions. In the same or other embodiments the hypervisor scheduler can be configur…

http://vxpertise.net/2012/06/summarizing-numa-scheduling/ Sitting on my sofa this morning watching Scrubs, I was thinking about the NUMA related considerations in vSphere – yes, I am a nerd. I read about this for the first time back in the days of vS…

A hypervisor calculates the total number of processor cycles (the number of processor cycles of one or more physical processors) in a first length of time based on the sum of the operating frequencies of the respective physical processors and the fir…

我有个windows服务程序,今天重点在测试系统逻辑.部署后,在看系统日志时,不经意看到一行:scheduler is shutted down. 2016-12-29 09:40:24.175 {"当前期计息日期":"2016/12/29","计息类型":"利息","当前期利息":0.36666666666666664,"总利息":0.36666666666666664,"月…

In this post we will see how to schedule Jobs using Quartz Scheduler with Spring. Spring provides couple of classes that simplify the usage of Quartz within Spring-based applications. Step 1: Provide Dependencies in Maven pom.xml <project xmlns="h…

有一台SQL Server(SQL Server 2014 标准版)服务器中的scheduler_count与cpu_count不一致,如下截图所示: SELECT  cpu_count ,         scheduler_count FROM    sys.dm_os_sys_info; SQL Server中Scheduler数量应该与逻辑CPU的核数一致,而sys.dm_os_sys_info中的scheduler_count 为8,少于cpu_count的12个数量,那么很有可能,有…

Problem: Windows Task Scheduler Fails With Error Code 2147943785 Solution: This is usually due to a permissions issue. It’s due to the user that is running the scheduled task not having the Log On As Batch Job assignment. To fix it, have your Network…

Fair Scheduler 队列设置经验总结 由于公司的hadoop集群的计算资源不是很充足,需要开启yarn资源队列的资源抢占.在使用过程中,才明白资源抢占的一些特点.在这里总结一下. 只有一个队列的资源小于设置的 最小资源时,才有可能启动资源抢占. 所有的资源队列的最小资源之后小于等于集群的资源总量都是合理的.如果最小资源之和大于集群的资源总量,同时又开启了资源抢占模式,那么资源调度就会不停的处于资源抢占的模式(这样的逻辑当然是不合理的了). 所有队列的最大资源配置之和可以大于集群的资源总…
