问题 TL;DR : Using linux kernel real time with NO_HZ_FULL I need to isolate a process in order to have deterministic results but /proc/interrupts tell me there is still local timer interrupts (among other). How to disable it? Long version : I want to make sure my program is not being interrupt so I try to use a real time linux kernel. I'm using the real time version of arch linux (linux-rt on AUR) and I modified the configuration of the kernel to selection the following options : CONFIG_NO_HZ_FULL

问题 We are writing a highly concurrent software in C++ for a few hosts, all equipped with a single ST9500620NS as the system drive and an Intel P3700 NVMe Gen3 PCIe SSD card for data. Trying to understand the system more for tuning our software, I dug around the system (two E5-2620 v2 @ 2.10GHz CPUs, 32GB RAM, running CentOS 7.0) and was surprised to spot the following: [root@sc2u0n0 ~]# cat /sys/block/nvme0n1/queue/scheduler none This contradicts to everything that I learned about selecting the

问题 im the new in Quartz.NET (v.3.0.3).I have console application and it's quartz host and broadcasting tcp.x:555/QuartzScheduler . In my company we have 2 app server machines and they're master-slave themselves.If master app is down slave take it's place.We will setup console application ( as a service ) in these servers. If we do that what happens in Quartz.NET , is these schedulers will be same or different ? PS: we're using MsSQL jobStore (AdoNetJobStore). Thank you for reply. 回答1: I found my

问题 I've a question regarding pthread implementation on Linux. Suppose a process has 5 threads. Now how does the scheduler sees these threads (or doesnt see at all). e.g. When scheduler is invoked, does it only schedule the main process, and then its the onus of the main process to schedule between each of its thread. Or is it the other way, that scheduler schedules each thread as if it is a separate process. 回答1: For modern Linux (NPTL pthread implementation), the scheduler schedules threads, a

问题 So this was one of my very first questions here, but I have a slight variation: So I have two people whose schedules are in a database. The schedules simply record the start time, end time, and description of the various events/appointments for both users. PersonA wants to trade appointments with PersonB. I want a MySQL query that will return all of them times that PersonB and PersonA can swap. Originally the parameters of the query were to throw out any appointments of PersonB where there

问题 My application has a View Model which contains a Lazy<BitmapImage> field. The field is populated using a service call to the server. In cases where the image is large, it takes a few seconds for the server to return the image (which is in fact a byte[] ) therefore the UI is blocked. To prevent this, I put the service call in a Task , so that a background thread gets the image and then calls the OnPropertyChanged to let the UI know the image is returned: Console.WriteLine("Outside Task

问题 I have spring boot application. Multiple Fargate tasks of same service is running. Now I have scheduler performed in service. So is scheduler will be performed twice as 2 tasks are running? How it behaves? 回答1: Yes. If the tasks are the same, and you expect each task to execute some work on a schedule, both will run the scheduled work. 来源： https://stackoverflow.com/questions/54333616/ecs-multiple-tasks-of-same-service-behaviour-for-scheduler

问题 I'm running vTiger 7.0 and I noticed on the first of the month, none of my invoices were created. I then took a look at the Scheduler and noticed that the "Last scan started" and "Last scan ended" fields show that none of the cron jobs had fired in days. The cron jobs are scheduled to fire in 15 minute intervals, with the exception of "RecurringInvoice" which runs every 12 hours. If I visit /myvtigerinstall/vtigercron.php, the cron jobs will all fire but nobody wants to have to manually run

问题 Here my code, static ScheduledExecutorService scheduler = null; scheduler.scheduleAtFixedRate(new Testing(),60, 24*60*60,TimeUnit.SECONDS); public static Runnable Testing() { System.out.println("Testing..."); } I want to call Runnable() method after 60 seconds later, but it call this method immediatly when i run the code. Is there any problem in my code. I'm new for scheduleAtFixedRate method. Thanks :) 回答1: Please try this scheduler.scheduleAtFixedRate(new Runnable() { @Override public void
