How to retrieve error message when running script on cluster
显示 更早的评论
Hi,
I am running batch jobs using MATLAB remotely on a cluster. How to view the eventual error messages(where I hope to find the line of code where the problem is)? Thanks in advance.

The task within the job object returned by the batch command has a property called Error which has the error stack. You could do something like this:
job = batch('assert(false)');
wait(job);
getReport(job.Tasks(1).Error)
Also note that if you simply call load on the job you'll see the error.

You can call the diary method while the job is running to do that (you need to be running a relatively recent version of Parallel Computing Toolbox for that to work). Unfortunately the diary method gives you the whole output each time, rather than a tail -f style.
>> j = batch('for ii=1:4,pause(1),disp(ii);end')
>> % After a short while...
>> diary(j)
Warning: The diary of this batch job might be incomplete because the job is still running.
