在SLURM中运行多文件程序

我正在浏览有关在家中设置小型SLURM集群的教程,并对以下内容感到好奇:到目前为止,所有示例/教程都讨论了执行单行代码,单个python脚本或者对于不同类型的输入等,群集上的单个可执行文件多次。

在我的例子中,我有一个名为main.py的主要python脚本,该脚本使用多个子目录中的模块,并且还有一个包含已使用的共享C库的子目录。如果我只告诉slurm执行main.py,比如说,使用以下脚本:

public String storagePermissions = Manifest.permission.READ_EXTERNAL_STORAGE;   
private static final int REQUEST_ACCESS =101;  

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
      if(checkSelfPermission(storagePermissions)== PackageManager.PERMISSION_GRANTED){
          result();    // result  is your block of code 
      }else {
          requestPermissions(new String[]{storagePermissions},REQUEST_ACCESS);
      }

    }
    else{
        result();    //so if user is lower than api verison M, no permission is requested
    } 

}

 private void showMessageOKCancel(String message, DialogInterface.OnClickListener okListener) {
    new AlertDialog.Builder(MainActivity.this)
            .setMessage(message)
            .setTitle("Hi User..")
            .setPositiveButton("Ok", okListener)
            .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {        //idea calling showMessage funtion again
                    Snackbar mySnackbar = Snackbar.make( findViewById(R.id.coordinatorlayout),"You Press Cancel.. ", Snackbar.LENGTH_INDEFINITE);
                    mySnackbar.setAction("Exit", new cancelButton());
                    mySnackbar.show();

                }
            })
            .create()
            .show();
}


private void result(){
          //your code
}

    @RequiresApi(api = Build.VERSION_CODES.M)
public class NeverAskAgain implements View.OnClickListener{
    @Override
    public void onClick(View view)
    {
        goToSettings();
    }
}
@RequiresApi(api = Build.VERSION_CODES.M)
private void goToSettings() {
    Intent myAppSettings = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + getPackageName()));
    finish();
    myAppSettings.addCategory(Intent.CATEGORY_DEFAULT);
    myAppSettings.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivityForResult(myAppSettings, REQUEST_APP_SETTINGS);
}
public class cancelButton implements View.OnClickListener{
    @Override
    public void onClick(View view){
        Toast.makeText(MainActivity.this,"To use this app , you must grant storage permission",Toast.LENGTH_SHORT);
        finish();
    }
    }


 @Override
@RequiresApi(api = Build.VERSION_CODES.M)
public void onRequestPermissionsResult(int requestCode, @NonNull String permissions[], @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode,permissions,grantResults);

    switch(requestCode) {
        case REQUEST_ACCESS:
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    // permission is granted
                    result();
                    break;
                }
                else if (!shouldShowRequestPermissionRationale(permissions[0])){
                    showMessageOKCancel("You choose Never Ask Again,option",
                new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Snackbar mySnackbar = Snackbar.make(findViewById(R.id.coordinatorlayout), "Permission=>Storage=>On", Snackbar.LENGTH_INDEFINITE);
                        mySnackbar.setAction("Settings", new NeverAskAgain());
                        mySnackbar.show();
                    }
                     });
                    break;
                }
                else {
                    showMessageOKCancel("You Denid permission Request..",
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            requestPermissions(new String[]{storagePermissions}, REQUEST_ACCESS);
                        }
                    });
                    break;
                }
        }
}

我将假设当main.py被发送到计算节点进行处理时会发生阻塞,因为计算节点在前面提到的子目录中没有任何python / C依赖项。

是否有必要有一个文件可执行文件,可能只引用所有计算节点上的预安装库以供slurm工作?

答案 0 :(得分:1)

Slurm希望计算节点可以使用所有依赖项和文件,通常是通过网络文件系统(如NFS)或并行文件系统(如Lustre)来命名为两个。
