To use sched_setaffinity to make the current process run on core 7 you do this: cpu_set_t my_set; /* Define your cpu_set bit mask. */ CPU_ZERO(&my_set); /* Initialize it all to 0, i.e. no CPUs selected. */ CPU_SET(7, &my_set); /* set the bit that represents core 7. */ sched_setaffinity(0, sizeof(cpu_set_t), &my_set); /* Set affinity of tihs … Read more
Another option is to use apscheduler‘s AsyncIOScheduler, which works more naturally with async functions (such as send_channel). In your case, you can simply write something of the form: scheduler = AsyncIOScheduler() scheduler.add_job(send_channel, trigger=tr) scheduler.start() Where tr is a trigger object. You can use either IntervalTrigger with a 1-day interval and a start date at 21:57, … Read more
If only 1 timer may ever be active at the same time, there are a couple of solutions. First of all the @Timer should probably be present on an @Singleton. In a Singleton methods are by default write-locked, so the container will automatically be locked-out when trying to invoke the timer method while there’s still … Read more
If you look at the documentation, there is a note that explicitly calls out this phenomenon. The note is under section 25.5.1 at this link, and reads: Make sure that you are not initializing multiple instances of the same @Scheduled annotation class at runtime, unless you do want to schedule callbacks to each such instance. … Read more
Advantage of ScheduledExecutorService over Timer I wish to offer you an alternative to Timer using – ScheduledThreadPoolExecutor, an implementation of the ScheduledExecutorService interface. It has some advantages over the Timer class, according to “Java in Concurrency”: A Timer creates only a single thread for executing timer tasks. If a timer task takes too long to … Read more
Actually under Windows you do not even have to create a batch file first to use the Scheduler. Open the scheduler: START -> All Programs -> Accesories -> System Tools -> Scheduler Create a new Task under tab Action, create a new action choose Start Program browse to Rscript.exe which should be placed e.g. here: … Read more
