UNIX subsystem on the Cray Time Sharing System (CTSS)

Conference ·
OSTI ID:5449343

A UNIX subsystem has been constructed for the Cray Time Sharing System (CTSS). The subsystem provides CTSS users with many System V facilities. UNIX processes are created by sub-partitioning a CTSS user process. The UNIX file system has been extended to permit UNIX data files to be stored in CTSS files or on a mass storage system. Each user of the subsystem has his own copy of the UNIX kernel and UNIX root filesystem. Major directories (/bin, /lib, etc) exist as read-only, mounted file systems, shared by all UNIX users. The addition of a new system call permits the execution of CTSS programs as UNIX processes.
