uniquetol give an "Unknown option specified" error when I run it on a cluster

1 view (last 30 days)
I have code that I'm trying to run on a cluster. I've tested my code on a local host and it works fine, but if I run it on my cluster the MATLAB built-in function `uniquetol` errors out.
I call my function with the following script:
%% submit_script.m
cluster = parcluster('MyGenericClusterProfile') % NOTE: if I change the cluster profile to 'local' I don't have any errors
job = createCommunicatingJob(cluster);
job.numWorkersRange=[1 1]; % Trying to get it to work on a single node before I scale up and add communications functionality
%% myFunction.m
function myFunction()
% Lots of code building and setting up arrays, some of which are
% gpuArrays but none of the ones in uniquetol are gpuArrays
class(A) % returns 'double' in Task1.diary.txt
[C,IA,IC]=uniquetol(A,1e-4,'highest'); % According to Task1.out.mat, generates a MATLAB:uniquetol:UnknowOptions ParallelException when run on cluster
If I comment out the 'highest' option of uniquetol while running on the cluster, my code runs without Exceptions but I need that option to get the correct run-time results. Why does my code behave differently depending on where I run it, and how do I make it behave correctly?

That option is new as of R2021b, the release after your cluster has.

Fixed the typo, for posterity.
Yeah, this is the issue. My development machine and the machine submitting the job are different, due to firewall reasons. I copy my code over to a login node and submit from there. I was certain the local development machine was R2021a but further investigation shows that it's actually R2021b.
