无法获得matlabpool启动

Question

我大约一年半以来一直在运行MATLAB.而且我一直在努力让matlabpool准备好在将近三个月内完成一次.在我完全放弃之前,我决定寻求帮助.:)

我的问题始于matlabpool命令.每当我输入matlabpool命令时,我都会得到:

One or more output arguments not assigned during call to "system_dependent".

Error in matlabpool>iIsOnClient (line 73)
onclient = ~system_dependent('isdmlworker');

Error in matlabpool>iVerifyJava (line 64)
if iIsOnClient()

Error in matlabpool (line 10)
iVerifyJava();

经过一些研究和不眠之夜,我发现必须使用"Cluster Profile Manager"解决问题.但我从来没有机会看到它的运作.以下是从Parallel面板中单击Cluster Profile Manager后得到的内容:

com.mathworks.jmi.MatlabException: Feature isdmlworker not found

    at com.mathworks.jmi.NativeMatlab.dispatchMTRequests(NativeMatlab.java:475)

收到此消息后,群集配置文件管理器会弹出,但除了"等待"符号之外不会显示任何内容.我已经检查了我的分布式计算许可证,这看起来也很好.

license checkout Distrib_Computing_Toolbox

命令返回1.

顺便说一下,还有另一条错误消息,我怀疑它与我的某种问题有关.我在每个MATLAB启动时得到这个:

Error using feature
Feature isdmlworker not found

Error in matlabrc (line 187)
if ~(ismcc || isdeployed || feature('isdmlworker')) && usejava('jvm')

除了所有这些之外; 每当我尝试从" 环境"选项卡打开"并行首选项"时,我都收到此消息:

com.mathworks.jmi.MatlabException: Feature isdmlworker not found
    at com.mathworks.jmi.NativeMatlab.SendMatlabMessage(Native Method)

    at com.mathworks.jmi.MatlabWorker$2.run(MatlabWorker.java:79)
    at com.mathworks.jmi.NativeMatlab.dispatchMTRequests(NativeMatlab.java:440)

我试图找到函数system_dependent.m但它似乎不存在.我得到的其他常见错误,功能"feature.m",选项"isdmlworker"是我找不到任何类型信息的其他谜团.

如果有人能帮我解决我在启动MATLAB的分布式计算系统时遇到的问题,我真的很感激.

编辑:我正在使用Ubuntu 14.04,而我的MATLAB版本是R2014a.

Answer 1

这似乎是您的 Ubuntu 14.04 特定安装的问题。不过，考虑到matlabpool错误发生在com.mathworks.jmi.NativeMatlab.dispatchMTRequests().

matlabpool经测试可以在 Ubuntu 15.04 和 15.10 上正常运行。这可能不是一个理想的解决方案，但将 Ubuntu 升级到 15.04 或 15.10 并重新安装 MATLAB R2014a 应该可以解决该问题。
