Data volume is getting larger every day in Mask Data Preparation (MDP). In the meantime, faster data handling is
always required. MDP flow typically introduces Distributed Processing (DP) system to realize the demand because using
hundreds of CPU is a reasonable solution. However, even if the number of CPU were increased, the throughput might be
saturated because hard disk I/O and network speeds could be bottlenecks. So, MDP needs to invest a lot of money to not
only hundreds of CPU but also storage and a network device which make the throughput faster.
NCS would like to introduce new distributed processing system which is called "NDE". NDE could be a distributed disk
system which makes the throughput faster without investing a lot of money because it is designed to use multiple
conventional hard drives appropriately over network. NCS studies I/O performance with OASIS® data format on NDE
which contributes to realize the high throughput in this paper.
