可以并行使用Win32 :: OLE来启动Matlab的多个实例吗? [英] Can Win32::OLE be used in parallel to start multiple instance of Matlab?

问题描述

当 Parallel::Loops 与

When Parallel::Loops is combined with Win32::OLE to create multiple instance of Matlab, if we use

my $ML = Win32::OLE->new('Matlab.Application') or die "Cannot start MATLAB"

在每个循环中，程序崩溃并显示未处理的异常.

in each loop, the program crashes showing an unhandled exception.

如果将my放在$ML之前，则它可以工作，但是在任何时候，只有一个实例在运行.

If drop the my before $ML then it works, but at any time only one instance is running.

推荐答案

我不确定在并行循环中创建多个MATLAB COM服务器有什么好处.

I'm not sure what is the benefit of creating multiple MATLAB COM servers in a parallel loop.

默认情况下，服务器以共享模式创建，即被所有实例共享. MATLAB引擎以单线程方式显示给用户，因此在您的情况下，所有客户端计算都以串行方式而不是并行方式运行.

By default the server is created in shared mode, ie shared by all instances. The MATLAB engine is exposed to the user as single-threaded, so in your case all the clients computations are run in serial, not in parallel.

幸运的是，您以专用模式创建了MATLAB COM服务器:

Fortunately you create MATLAB COM server in dedicated mode:

Win32::OLE->new('Matlab.Application.single')
