Introduction
ZOID is an I/O forwarding component of the ZeptoOS project. Any communication between the compute nodes and I/O nodes (job management, file I/O, sockets) is facilitated by ZOID.
ZOID infrastructure consists of:
- Multithreaded zoid daemon on the I/O nodes which performs I/O forwarding for the compute nodes and which also communicates with the service node to perform job management,
- control daemon on the compute nodes which is responsible for job management tasks such as launching application processes, for the forwarding of stdin/out/err data, and for forwarding of IP packets,
- zoid-fuse daemon on the compute nodes which performs file I/O forwarding for POSIX-compliant applications.
