Computer work chain and a method for performing a work chain in a computer

A method for processing work requests in a work chain comprising:

• A) in a work queue handler of the work chain, receiving a work request at an input to the work chain;
• B) in the work queue handler, selecting a work queue at a position, J, in a linked list of M work queues to process the work request and allocating the work request to the Jth work queue, where M is a positive integer that is greater than or equal to one and where J is a non-negative integer having a value that ranges from J=0 to J=N, where N=M−1, and wherein each work queue comprises a respective queue monitor, a respective exception monitor, a respective pool of worker threads, a respective logger, and a respective data queue;
• C) in the Jth work queue, receiving the work request at an input of the Jth work queue and attempting to process the work request, wherein if the Jth work queue is successful at processing the work request, the Jth work queue outputs a work result from an output of the Jth work queue;
• D) if the Jth work queue was successful at producing the work result, sending a notification from the Jth work queue to the work queue handler to indicate that the Jth work result has been successfully produced;
• E) in the work queue handler, if the notification has been received in the work queue handler, determining whether the value of J is equal to N, and wherein if the value of J is not equal to N, incrementing the value of J from a previous J value to a new J value, and wherein after J has been incremented, the method returns to step C) with the work result produced at the output of the work queue at the Jth position in the linked list corresponding to the previous J value being provided as a work request at the input of the work queue at the Jth position in the linked list corresponding to the new J value;
• and
• F) if it is determined at step E that the notification has been received and that the value of J is equal to N, causing the Jth work result to be output from an output of the work chain.

A computer-readable medium having a computer program stored thereon comprising computer instructions for processing by a processing device to perform a work chain, the program comprising:

• a first set of computer instructions for receiving a work request at an input to the work chain;
• a second set of computer instructions for selecting a work queue at a position, J, in a linked list of M work queues to process the work request and allocating the work request to the Jth work queue, where M is a positive integer that is greater than or equal to one and where J is a non-negative integer having a value that ranges from J=0 to J=N, where N=M−1, and wherein each work queue comprises a respective queue monitor, a respective exception monitor, a respective pool of worker threads, a respective logger, and a respective data queue;
• a third set of computer instructions for performing a Jth work queue algorithm that attempts to process the work request in the Jth work queue, wherein if the Jth work queue algorithm is successful at processing the work request, the Jth work queue algorithm outputs a work result from an output of the Jth work queue and outputs a call back notification, wherein the notification provides an indication that the Jth work result has been successfully produced, wherein the Jth work queue algorithm includes a Jth work queue monitor, a Jth exception monitor, a Jth pool of worker threads, a Jth logger, and a Jth data queue;
• and
• a fourth set of instructions for determining whether the call back notification has been output by the third set of instructions, and if so, whether the value of J is equal to N, and wherein if the value of J is not equal to N, the fourth set of instructions causes the value of J to be incremented from a previous J value to a new J value, and wherein after J has been incremented, the third set of instructions uses the work result produced at the output of the work queue at the Jth position in the linked list corresponding to the previous J value to be used as a work request at the input of the work queue at the Jth position in the linked list corresponding to the new J value, and wherein if the fourth set of instructions determines that the notification has been output by the third set of instructions and that the value of J is equal to M−1, the fourth set of instructions causes the work result output from the Jth work queue to be output from an output of the work chain.
