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 I/O nodes which performs I/O forwarding and communicates with the service node,
• control daemon on 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 compute nodes which performs file I/O forwarding for POSIX-compliant applications.
