无法在Slurm，Ubuntu16.04服务器的Matlab中创建Parpool

Question

我在Slurm中在Matlab中创建Parpool遇到了一些麻烦

当我提交工作时，它会卡住：

Parpool大小：24

Starting parallel pool (parpool) using the 'local' profile ...

or error

{Error using parpool (line 104)
Failed to start a parallel pool. (For information in addition to the causing
error, validate the profile 'local' in the Cluster Profile Manager.)


Error in run (line 86)
evalin('caller', [script ';']);

Caused by:
    Error using parallel.internal.pool.InteractiveClient>iThrowWithCause (line
    666)
    Failed to initialize the interactive session.
        Error using
        parallel.internal.pool.InteractiveClient>iThrowIfBadParallelJobStatus
        (line 767)

这通常是由于Linux上用于Matlab的Java版本不兼容。 问题：

echo $MATLAB_JAVA

如果设置了此变量，则可以取消设置此选项，并让Matlab使用其自己的java。 您可以运行如下脚本：

#!/bin/sh unset MATLAB_JAVA matlab -desktop
