− | == How can I use many small files efficiently? ==
| |
− |
| |
− | You can gain in performance and minimize the pressure under /data in two cases:
| |
− | * '''case1''' your jobs are only reading under the directories where your zotfiles reside
| |
− | * '''case2''' your jobs generate zotfiles, but they will be accessed only for reading afterwards
| |
− |
| |
− | For '''case1''':
| |
− | * convert your zotfiles directories to squashfs images
| |
− | * in your jobs:
| |
− | ** mount those images using '''sudo mountimg'''
| |
− | ** use those mounted directories for processing
| |
− |
| |
− | For '''case2''':
| |
− | * generates your zotfiles on the local filesystems of the node (ex: /tmp)
| |
− | * convert them to squashfs images under /data
