Database transaction schedule. In the fields of databases and transaction processing (transaction management), a schedule (or history) of a system is an abstract model to describe the order of executions in a set of transactions running in the system. Often it is a list of operations (actions) ordered by time, performed by a set of transactions ...
Database transaction scheduling. In the fields of databases and transaction processing (transaction management), a schedule (or history) of a system is an abstract model to describe execution of transactions running in the system. Often it is a list of operations (actions) ordered by time, performed by a set of transactions that are executed ...
The critical path method ( CPM ), or critical path analysis ( CPA ), is an algorithm for scheduling a set of project activities. [ 1] A critical path is determined by identifying the longest stretch of dependent activities and measuring the time [ 2] required to complete them from start to finish. It is commonly used in conjunction with the ...
Round-robin algorithm is a pre-emptive algorithm as the scheduler forces the process out of the CPU once the time quota expires. For example, if the time slot is 100 milliseconds, and job1 takes a total time of 250 ms to complete, the round-robin scheduler will suspend the job after 100 ms and give other jobs their time on the CPU.
Schedule M (2009 and 2010) was used to claim the Making Work Pay tax credit (6.2% earned income credit, up to $400). [5] Schedule R is used to calculate the Credit for the Elderly or the Disabled. Schedule SE is used to calculate the self-employment tax owed on income from self-employment (such as on a Schedule C or Schedule F, or in a ...
A precedence graph, also named conflict graph [1] and serializability graph, is used in the context of concurrency control in databases. [2] It is the directed graph representing precedence of transactions in the schedule, as reflected by precedence of conflicting operations in the transactions. A schedule is conflict-serializable if and only ...

Parallel task scheduling (also called parallel job scheduling [1] [2] or parallel processing scheduling [3]) is an optimization problem in computer science and operations research. It is a variant of optimal job scheduling. In a general job scheduling problem, we are given n jobs J1 , J2 , ..., Jn of varying processing times, which need to be ...
