Error using matlab parfor
Posted: Thu Jul 31, 2014 9:39 am
Hi all,
I seem to run into an issue when I run some of my matlab code in parallel (using the matlab parfor). While it works without issues when run sequentially, if I try to run the same code in parallel I get the following error. As far as omero is concern, I only try and download data, using the 'getHypercube' method. Too many too concurrent access? That's only 6 workers though. Any help appreciated (still on omero 4)
Many thanks
