Patent number: 10255209Abstract: Embodiments of the present invention disclose a method, computer program product, and system for determining statistics corresponding to data transfer operations. In one embodiment, the computer implemented method includes the steps of receiving a request from an input/output (I/O) device to perform a data transfer operation between the I/O device and a memory, generating an entry in an input/output memory management unit (IOMMU) corresponding to the data transfer operation, wherein the entry in the IOMMU includes at least an indication of a processor chip that corresponds to the memory of the data transfer operation, monitoring the data transfer operation between the I/O device and the memory, determining statistics corresponding to the monitored data transfer operation, wherein the determined statistics include at least: the I/O device that performed the data transfer operation, the processor chip that corresponds to the memory of the data transfer operation, and an amount of data transferred.Type: GrantFiled: February 7, 2017Date of Patent: April 9, 2019Assignee: International Business Machines CorporationInventors: Srinivas Kotta, Mehulkumar J.

Patent number: 10241926Abstract: A computer-implemented method for migrating a buffer used for direct memory access (DMA) may include receiving a request to perform a DMA data transfer between a first partitionable endpoint and a buffer of a first memory in a system having two or more processor chips. Each processor chip may have an associated memory and one or more partitionable endpoints. The buffer from the first memory may be migrated to a second memory based on whether the first memory is local or remote to the first partitionable endpoint, and based on a DMA data transfer activity level. A memory is local to a partitionable endpoint when the memory and the partitionable endpoint are associated with a same processor chip. The DMA data transfer may then be performed.Type: GrantFiled: December 22, 2017Date of Patent: March 26, 2019Assignee: International Business Machines CorporationInventors: Mehulkumar J.

Patent number: 10114673Abstract: A method for scheduling the execution of a computer instruction, receive an entitlement processor resource percentage for a logical partition on a computer system. The logical partition is associated with a hardware thread of a processor of the computer system. The entitlement processor resource percentage for the logical partition is stored in a register of the hardware thread associated with the logical partition. An instruction is received from the logical partition of the computer system and the processor dispatches the instruction based on the entitlement processor resource percentage stored in the register of the hardware thread associated with the logical partition.Type: GrantFiled: September 29, 2016Date of Patent: October 30, 2018Assignee: International Business Machines CorporationInventors: Nitin Gupta, Mehulkumar J.

Patent number: 9898301Abstract: When a main processor issues a command to co-processor, a timeout value is included in the command. As the co-processor attempts to execute the command, it is determined whether the attempt is taking time beyond what is permitted by the timeout value. If the timeout is exceeded then responsive action is taken, such as the generation of a command timeout type failure message. The receipt of the command with the timeout value, and the consequent determination of a timeout condition for the command, may be determined by: the co-processor that receives the command, or a watchdog timer that is separate from the co-processor. Also, detection of co-processor hang and/or hung co-processor conditions during the time that a co-processor is executing a command for the main processor.Type: GrantFiled: June 20, 2014Date of Patent: February 20, 2018Assignee: International Business Machines CorporationInventors: Nitin Gupta, Mehulkumar J.
