Methods and systems for managing memory buffer usage while processing computer system operations

A system comprising:

• a memory buffer configured to store data;
• and
• a transaction queue communicably coupled with the memory buffer, the transaction queue configured to receive a transaction, a buffer allotment request, and a buffer release command wherein:
• the transaction requires storage space in the memory buffer;
• the buffer allotment request comprises a first buffer usage indicator corresponding to the storage space required in the memory buffer for executing the transaction;
• and
• a buffer arbiter configured to receive the buffer allotment request and to preclude the transaction from executing in response to the buffer allotment request until the buffer arbiter determines the memory buffer has the sufficient storage space to execute the transaction defined by the first buffer usage indicator;
• and
• the buffer release command comprises a second buffer usage indicator corresponding to storage space in the memory buffer that will be released after execution of the transaction, wherein the buffer release command is scheduled to be processed following processing of the transaction such that the storage space in the memory buffer used for executing the transaction is released.

A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code instructions comprising program code instructions to:

• receive, by a transaction queue, a transaction and a buffer allotment request, wherein the transaction requires storage space in a memory buffer communicably coupled with the transaction queue, and wherein the buffer allotment request comprises a first buffer usage indicator corresponding to the storage space required in the memory buffer to execute the transaction;
• preclude, by a buffer arbiter, in response to processing the buffer allotment request, the transaction from processing until determining the memory buffer has the sufficient storage space for executing the transaction defined by the first buffer usage indicator;
• execute the transaction in response to determining the memory buffer has sufficient storage space;
• receive, by the transaction queue, a buffer release command comprising a second buffer usage indicator corresponding to storage space in the memory buffer that will be released after execution of the transaction;
• and
• process the buffer release command following completion of processing of the transaction such that the storage space in the memory buffer used for executing the transaction is released.
