Overview of HPCC file systems

Home, Research and Scratch are network file systems, meaning that each node in the cluster must go through the network switch to access these spaces. Please refer to individual wiki pages (Home, Research, and Scratch) in this section for how to use each of them.

The ufs18 file system is a 2018 IBM General Parallel File System (GPFS) installed for the HPCC to store the home and research spaces. While it is faster and more stable, users need to learn its differences from other file systems and understand how to use it. Please see UFS18 file system.

/tmp and /mnt/local are locally accessible in the hard drive of each node. The space is not affected by the network and has larger size compared with the RAMDISK /dev/shm which is located inside the node's RAM. However, /dev/shm is the closest storage location for files. Files stored here take up some of the node's memory space. For more information, please have a look at Local file system and Guidelines for Choosing File Storage and I/O.
