Data processing system with monitoring and regulation of processor free time

Claim 2

In a data processing system, apparatus for measuring and regulating computer work load, the work load comprising calls randomly originated and processed through said system, in which the processing of priority tasks within said system is initiated within the computer at predetermined time intervals, the invention comprising: means for monitoring the condition of said computer at successive timed subintervals, means for counting and storing a continuing count of the total of one of said monitored conditions over a predetermined timed period comprising a multiple of said time intervals, a first and a second settable register for storing first and second numbers representing upper and lower limits for said count, means operative at the end of said timed period for comparing said stored count against said upper and lower limits, and a work load regulator responsive to the results of the comparison between the monitored count and the limits for regulating the number of calls processed by said computer.

Claim 3

In a system as claimed in claim 1, wherein said apparatus further includes a second register coupled to receive data on the number of calls originated in said system during said timed period.

Claim 4

In a processing system as claimed in claim 2, wherein the apparatus further includes means for setting the register at one of a plurality of work load levels to thereby set said register for a desired work load for said computer.

Claim 7

Apparatus for regulating the work load of a computer in a data processing system, the work load being comprised of randomly initiated new calls entering said system as processed by said computer during short duration processing cycles, said apparatus including means for monitoring new calls initiated into said system and for storing the number of said new calls initiated during a timed period, a register settable to one of a plurality of positions each representing a number of new calls into said system whereby to control the number of new initiated calls to be processed by said computer, means for monitoring the computer at recurring finite intervals of time and for maintaining a count of the busy status of said computer encountered at said intervals during said timed period, means operative at the end of said timed period for comparing said count against an upper and a lower set count, and output paths from said comparing means for resetting said register to another position in response to said count corresponding to one of said set counts.

Claim 8

Apparatus for regulating the work load of a computer in a data processing system, the work load being comprised of randomly initiated new calls entering said system as processed by said computer during short duration processing cycles, said apparatus including means for monitoring new calls initiated into said system and for storing the number of said new calls initiated during a timed period, a register settable to one of a plurality of positions each representing a number of new calls into said system whereby to control the number of new initiated calls to be processed by said computer, means for monitoring the computer at recurring finite intervals of time and for maintaining a count of the busy status of said computer encountered at said intervals during said timed period, means operative at the end of said timed period for comparing said count against an upper and a lower set count, and output paths from said comparing means for resetting said register to another position in response to said count corresponding to one of said set counts.

Claim 9

An apparatus as claimed in claim 5, in which said new call register comprises a plurality of counters settable to a plurality of new call levels and in which there are gating means coupling the output of each of said counters to a separate one of said call level positions, and in which there is a comparator for comparing the output of said new call counter with the output of said gating means.

Claim 10

An apparatus as claimed in claim 5, in which said settable register comprises a counter with a down count input and an up count input, said inputs each comprising outputs of said count comparing means.
