Shared storage on our clusters is not designed to handle lots of small files (they are optimized for very large files). Make sure that the data set which you need for your training is an archive format like tar, which you can then transfer to your job's compute node when the job starts. If you do not respect these rules, you risk causing enormous numbers of I/O operations on the shared filesystem, leading to performance issues on the cluster for all of its users. If you want to learn more about how to handle collections of large number of files, we recommend that you spend some time reading this page.
