Crontab – simple echo not running

May be it is, cron jobs will run in their own shell. So you can’t expect to see asdf on your console. What you should try is * * * * * echo asdf > somefile_in_your_home_directory_with_complete_path.log Next check the file by doing a tail: tail -f somefile_in_your_home_directory_with_complete_path.log And if it’s not, check if the cron … Read more

Reschedule timer in android

If you see the documentation on Timer.cancel() you’ll see this: “Cancels the Timer and all scheduled tasks. If there is a currently running task it is not affected. No more tasks may be scheduled on this Timer. Subsequent calls do nothing.” You’ll need to initialize a new Timer when you are rescheduling: EDIT: public void … Read more

OpenMP Dynamic vs Guided Scheduling

What affects the runtime of guided scheduling? There are three effects to consider: 1. Load balance The whole point of dynamic/guided scheduling is to improve the distribution of work in the case where not each loop iteration contains the same amount of work. Fundamentally: schedule(dynamic, 1) provides optimal load balancing dynamic, k will always have … Read more

Quartz.Net how to create a daily schedule that does not gain 1 minute per day

You aren’t specifying the interval which happens to default to 1 minute, so it assumes you want to run the job every minute. Try ITrigger trigger = TriggerBuilder.Create() .WithDailyTimeIntervalSchedule (s => s.WithIntervalInHours(24) .OnEveryDay() .StartingDailyAt(TimeOfDay.HourAndMinuteOfDay(13, 0)) ) .Build(); The default should be to run every day, so the OnEveryDay() isn’t really needed. Not sure why you … Read more

VBA Macro On Timer style to run code every set number of seconds, i.e. 120 seconds

When the workbook first opens, execute this code: alertTime = Now + TimeValue(“00:02:00”) Application.OnTime alertTime, “EventMacro” Then just have a macro in the workbook called “EventMacro” that will repeat it. Public Sub EventMacro() ‘… Execute your actions here’ alertTime = Now + TimeValue(“00:02:00”) Application.OnTime alertTime, “EventMacro” End Sub

how to shield a cpu from the linux scheduler (prevent it scheduling threads onto that cpu)?

The answer is to use cpusets. The python cpuset utility makes it easy to configure them. Basic concepts 3 cpusets root: present in all configurations and contains all cpus (unshielded) system: contains cpus used for system tasks – the ones which need to run but aren’t “important” (unshielded) user: contains cpus used for “important” tasks … Read more

Tennis match scheduling

Preface In Prolog, CLP(FD) constraints are the right choice for solving such scheduling tasks. See clpfd for more information. In this case, I suggest using the powerful global_cardinality/2 constraint to restrict the number of occurrences of each round, depending on the number of available courts. We can use iterative deepening to find the minimal number of admissible … Read more
