operating system designed exclusively for a special model of the system 360 line of mainframes the model 67 made available on a trial basis to a limited set of customers in 1967 it was never officially released as a supported product by ibm tss pioneered a number of novel features some of which later appeared in more popular systems such as mvs tss was migrated to system 370 and 303x systems but despite its many advances and novel capabilities tss failed to meet expectations and was eventually canceled tss 370 was used as the basis for a port of unix to the ibm mainframe 1 tss 360 also inspired the development of the tss 8 operating system 2 contents 1 novel characteristics 2 user interface 3 position independent code 4 criticism 5 see also 6 references 7 further reading 8 external links novel characteristics edit tss 360 was one of the first implementations of tightly coupled symmetric multiprocessing a pair of model 67 mainframes shared a common physical memory space and ran a single copy of the kernel and application code an i o operation launched by one processor could end and cause an interrupt in the other the model 67 used a standard 360 instruction called test and set to implement locks on code critical sections it also implemented virtual memory and virtual machines using position independent code 3 tss 360 included an early implementation of a table driven scheduler a user configured table whose columns were parameters such as current priority working set size and number of timeslices used to date the kernel would refer to this table when calculating the new priority of a thread this later appeared in systems as diverse as honeywell cp v and ibm z os as was standard with operating system software at the time tss 360 customers such as general motors research laboratories were given full access to the entire source of the operating system code and development tools user developed improvements and patches were frequently incorporated into the official source code user interface edit tss provides users a command line interface 4 users interact with the command system the command format consists of command_name operands the command name is one to eight characters without imbedded blanks the operands are optional depending on the command and must be separated from the command name by at least one blank multiple operands should be separated by tab characters or commas command lines can be continued by typing a hyphen at the end of the line to be continued and typing the continuation at the beginning of the next line multiple commands can be written on a line by separating them with semicolons comments are allowed in command lines separated from the command with a semicolon and included in single quotes operands can be either positional or keyword with the format keyword value system commands are divided into seven categories task management logon logoff abend etc data management catalog ddef delete etc program management load dump display trap etc command creation procdef builtin message handling user profile synonym default profile etc program product language interface asm assembler f cobol hasm assembler h pli pl i f pliopt pl i optimizing compiler ftnh fortran h etc position independent code edit tss provided an early implementation of position independent code the ability to have different processes run a single copy of an executable possibly mapped to a different virtual addresses in each process each procedure may have a read only public csect a writable private prototype section psect and a writable save area typically located in the psect address constants of external procedures and entry points must be located in the psect since the dynamic loader 5 will not place a routine at the same virtual address in every process a program that follows type i linkage conventions is generally responsible at entry for saving its registers in the save area pointed to by register 13 retrieving the address of its psect from word 19 of the save area chaining the save area to a new save area and putting the address of the new save area in register 13 a caller that follows type i linkage conventions loads a v constant for the routine into general register 15 gr15 and copies an r constant for the routine s psect into the 19th word of the save area pointed to be gr13 prior to calling that routines 6 7 when the dynamic loader loads a program it makes a copy of the psect and relocates the adcons to reflect the virtual addresses assigned within the current process therefore each user of the program has a unique copy of the psect the dynamic loader does not load program pages or resolve address constants until the first page fault criticism edit this section does not cite any

suffered from performance and reliability problems and lack of compatibility with os 360 although those issues were eventually addressed ibm attempted to develop tss on a very aggressive schedule with a large staff of programmers to compete with multics by 1967 it had become evident that tss 360 was suffering from the same kinds of delays as os 360 in february 1968 at the time of share 30 there were eighteen s 360 67 sites attempting to run tss during the conference ibm announced via blue letter that tss 360 was being decommitted a great blow to the time sharing community this decision was temporarily reversed and tss 360 was not officially canceled until 1971 however tss 360 continued to be quietly available for a time to existing tss 360 customers as an interim measure after tss 360 was canceled ibm put its primary efforts into the time sharing option tso a time sharing monitor for os 360 several other groups developed less ambitious more successful time sharing systems for the s 360 67 notably cp 67 at ibm s cambridge scientific center an early virtual machine monitor which evolved into vm 370 mts at the university of michigan and orvyl at stanford university ibm also provided the tss 370 prpq as a migration path for existing tss 360 customers which went through multiple releases see also edit history of ibm mainframe operating systems time sharing system evolution
