Matlab并行计算工具包本地配置验证失败

Question

我刚刚开始使用并行计算工具包，每当我调用 matlabpool open 时，我都会收到以下错误：

??? Error using ==> matlabpool at 127
The interactive parallel job errored with the following message:

Unable to get version information from job. This probably means
that the job was created in a client MATLAB prior to the R2009a
general release, or that the jobdata files of the job are corrupt

我的 MATLAB 版本是 2010a，并且是相当新的安装。我之前没有对配置进行任何更改，所以它应该是默认的。当我进入配置管理器并验证本地配置时，我得到了以下结果：

**Find Resource**: Passed

**Matlabpool**: Skipped

我在其他地方读到命令 distcomp.feature( 'LocalUseMpiexec', false ) 对某些人有效，但它有对我来说没有任何影响，相同的测试失败并报告相同的错误。

以前有人遇到过这个吗？

Answer 1

这看起来真的很奇怪，我以前从未见过这种失败（而且我可能比大多数人更多地使用本地调度程序）。我唯一可以建议的是你删除本地调度程序的DataLocation 的全部内容。您可能还需要检查 DataLocation 是否指向旧位置。您可以执行以下操作：

s = findResource( 'scheduler', 'Configuration', 'local' );
s.DataLocation % navigate to this directory, delete all contents
% now, restart MATLAB

如果这没有帮助，我建议联系 MathWorks 安装支持。
