So my need is before writing in the output files. i want to get all lines in a list to

问题 I need to launch a child process in my java application in Windows, and eventually my java app can be killed/terminated via task manager. So I need to "link" this child process with the parent process, to both be terminated if the parent process terminate. In windows API we have the CreateJobObject and also the: SetInformationJobObject JOBOBJECT_EXTENDED_LIMIT_INFORMATION structure JOBOBJECT_BASIC_LIMIT_INFORMATION structure And the LimitFlag JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE Based on the

springBoot启动时，选择可执行的任务

由 ◇◆丶佛笑我妖孽 提交于 2019-12-07 17:03:39
一次。。有人问我：“boot 启动时 如果想要执行一些任务怎么做？” 我特二的回答。放在spring auto 启动配置项里面 然后在spring容器启动的时候注入。或者使用动态代理。做切面。 虽然上述方式貌似可以执行。但有点复杂。其实boot提供了一种启动后就做的任务操作。 CommandLineRunner 看源码说明为： Spring Batch jobs. Runs all jobs in the surrounding context by default. Can also be used to launch a specific job by providing a jobName。 即，在spring容器启动的时候就开始批处理一些任务。是随spring启动而加载运行的。 使用方式：自定义一个model 实现该及接口并重写run 方法 package org.springboot.sample.runner; import org.springframework.boot.CommandLineRunner; import org.springframework.stereotype.Component; @Component public class MyStartupRunner implements CommandLineRunner { @Override

Submit job with python code (mpi4py) on HPC cluster

由 ↘锁芯ラ 提交于 2019-12-07 10:51:53
问题 I am working a python code with MPI (mpi4py) and I want to implement my code across many nodes (each node has 16 processors) in a queue in a HPC cluster. My code is structured as below: from mpi4py import MPI comm = MPI.COMM_WORLD size = comm.Get_size() rank = comm.Get_rank() count = 0 for i in range(1, size): if rank == i: for j in range(5): res = some_function(some_argument) comm.send(res, dest=0, tag=count) I am able to run this code perfectly fine on the head node of the cluster using the

Submit Spark job on Yarn cluster

问题 I am struggling for more than 2 days now with the following problem. I wrote a basic "HelloWorld" script in Scala: object Hello extends App{ println("WELCOME TO A FIRST TEST WITH SCALA COMPILED WITH SBT counting fr. 1:15 with sleep 1") val data = 1 to 15 for( a <- data ){ println( "Value of a: " + a ) Thread sleep 1000 } That I then compiled with SBT in order to get a JAR compiled version. I transferred then everything on a cluster (which is Horthonworks sandbox running on a virtual Linux

Monthly jobs on every 30th day using Quartz

由 假装没事ソ 提交于 2019-12-07 08:42:30
问题 guys, I have monthly jobs scheduled(using Quartz) by users. Users provide starting date f or first job to run, it could be any day of month 1-31 My question is how to schedule this using cron trigger, having in mind that not all month have 31,30,29th days. In such case job should run closest previous day of the month. So, lets say April has only 30 days, so job has to run on 30th of April. Can it be done using single cron trigger? Or should it be combination of triggers? I tried to play with

如何对SAP Leonardo上的机器学习模型进行重新训练

由 独自空忆成欢 提交于 2019-12-06 22:02:15
Jerry之前的两篇文章介绍了如何通过Restful API的方式，消费SAP Leonardo上预先训练好的机器学习模型： 如何在Web应用里消费SAP Leonardo的机器学习API 部署在SAP Cloud Platform CloudFoundry环境的应用如何消费 当时Jerry提到，Product Image Classification API只支持29种产品类别： 如果我们开发应用时需要支持额外的产品类别，就得需要自行提供该产品类别的图片并重新训练。 下面是SAP Leonardo上机器学习模型的重新训练步骤。 假设我们期望重新训练之后，Product Image Classfication这个模型能够识别出不同种类的花，那么我们首先得搞到大量花的图片。Tensorflow的官网上，已经体贴地给想做模型训练的学习者们，提供了一个做练习用的压缩包，里面包含了大量各式花的图片。 http://download.tensorflow.org/example_images/flower_photos.tgz SAP Leonardo接受的能用于重新训练模型的数据集，必须符合下列的层级结构，即training, validation和test三个文件夹下面，分别包含以产品类别命名的字文件夹，且数据规模之比为8:1:1. 有了用于训练的数据后，下一步就是把这些数据上传到SAP

Android JobScheduler onStartJob called multiple times

由 a 夏天 提交于 2019-12-06 17:45:23
问题 The JobScheduler calls onStartJob() multiple times, although the job finished. Everything works fine, if I schedule one single job and wait until it has finished. However, if I schedule two or more jobs with different IDs at the same time, then onStartJob() is called again after invoking jobFinished() . For example I schedule job 1 and job 2 with exactly the same parameters except the ID, then the order is: onStartJob() for job 1 and job 2 Both jobs finish, so jobFinished() is invoked for
