Patent number: 11907589Abstract: At least one application of a client executes via system software on a hardware computing system that includes at least one CPU and at least one coprocessor. A virtualization layer establishes unified memory address space between the client and the hardware computing system, which also includes memory associated with the at least one coprocessor. The virtualization layer then synchronizes memory associated with the client and memory associated the at least one coprocessor. The virtualization layer may be installed and run in a non-privileged, user space, without modification of the application or of the system software running on the hardware computing system.Type: GrantFiled: July 8, 2019Date of Patent: February 20, 2024Assignee: VMware, Inc.Inventors: Aidan Cully, Mazhar Memon

Publication number: 20230393898Abstract: A pre-emptive scheduling of workloads enables improved sharing of resources of a cluster of hosts. The steps of this pre-emptive scheduling method include: adjusting priority of active workloads that are each running on one of the nodes and idle workloads that have been suspended; determining that a priority of a first workload, which is one of the idle workloads, exceeds a priority of a second workload, which is one of the active workloads and is executing on a first node of the cluster of nodes; and suspending the second workload and resuming the first workload to run on the first node.Type: ApplicationFiled: March 20, 2023Publication date: December 7, 2023Inventors: Aidan CULLY, Earl Campbell RUBY, III

Patent number: 11822925Abstract: Execution of multiple execution streams is scheduled on at least one coprocessor. A software layer located logically between applications and the at least one coprocessor intercepts a first API call from an application and determines that a first execution stream is to be executed. Before scheduling the first execution stream, the software layer transmits a response to the application indicating that the at least one coprocessor is ready to execute another execution stream. The software layer intercepts a second API call from the application and determines that a second execution stream including one or more kernels is to be executed. The software layer determines that the one or more kernels does not have a dependency on the first execution stream. The software layer schedules the one or more kernels for execution prior to when the at least one coprocessor has completed execution of the first execution stream.Type: GrantFiled: March 15, 2021Date of Patent: November 21, 2023Assignee: VMware, Inc.Inventors: Mazhar Memon, Aidan Cully

Patent number: 11762672Abstract: A method for a dynamic linker to load and run an application that is executed over a plurality of nodes, includes relocating a primary binary of the application from an initial location to an executable location, loading library dependencies, altering a system call table used during execution of the application for the dynamic linker to catch all system calls made by the application, and executing the relocated primary binary from the executable location.Type: GrantFiled: October 4, 2021Date of Patent: September 19, 2023Assignee: VMware, Inc.Inventor: Aidan Cully

Publication number: 20220308940Abstract: A method for allocating and using file descriptors for an application executing over a plurality of nodes, each having a file system, includes receiving a system call from the application running on a first node to access a file in a file system, determining whether the file resides in a file system of a first node or the second node, and upon determining that the file resides on the second node, sending the system call and arguments of the system call to the one of the second nodes for execution on the one of the second nodes and returning a result of the system call executed on the second node to the application on the first node.Type: ApplicationFiled: October 4, 2021Publication date: September 29, 2022Inventors: Aidan CULLY, Vance MILLER

Publication number: 20220308950Abstract: A method for handling system calls during execution of an application over a plurality of nodes including a first node and a second node, includes receiving a system call from a thread running on the first node, determining that executing the system call involves resources present on the second node, sending the system call and arguments of the system call to the second node for the second node to execute the system call, receiving the results of the system call from the second node, and returning the results of the system call to the thread.Type: ApplicationFiled: October 4, 2021Publication date: September 29, 2022Inventors: Aidan CULLY, Mazhar MEMON
-
Publication number: 20220308936Abstract: A method for executing an application over a plurality of nodes in each of which an application monitor and a runtime are executing includes executing a first portion of the application by first threads of the runtime of the first node and a second portion of the application by second threads of the runtime of the second node, and under control of the application monitors of the first and second nodes and while executing the first portions and second portions of the application, migrating workloads of one or more of the first threads from the first node to the second node for execution by the second threads.Type: ApplicationFiled: October 4, 2021Publication date: September 29, 2022Inventors: Aidan CULLY, Vance MILLER, Dusan VELJKO, Mazhar MEMON

Patent number: 10949211Abstract: Execution of multiple execution streams is scheduled on a plurality of coprocessors. A software layer located logically between applications and the coprocessors determines dependencies within the execution streams, each said dependency being a condition in one of the execution streams that must be satisfied in order for execution of at least one other of the execution streams to proceed on corresponding ones of the coprocessors. The dependencies are then represented in a data structure and an optimized execution schedule is determined for the execution streams according to the dependencies. Simultaneous execution of a plurality of the execution streams is then dynamically reordered according to the optimized execution schedule.Type: GrantFiled: December 20, 2018Date of Patent: March 16, 2021Assignee: VMware, Inc.Inventors: Mazhar Memon, Aidan Cully

Patent number: 10420140Abstract: Multicast transmissions are efficient but do not allow for individual acknowledgement that the data was received by each receiver. This is not acceptable for isochronous systems that require specific levels of QoS for each device. A multimedia communications protocol is provided that uses a novel multi-destination burst transmission protocol in multimedia isochronous systems. The transmitter establishes a bi-directional burst mode for multicasting data to multiple devices and receiving Reverse Start of Frame (RSOF) delimiters from each multicast-destination receiver in response to multiple SOF delimiters, thus providing protocol-efficient multi-destination acknowledgements.Type: GrantFiled: October 10, 2017Date of Patent: September 17, 2019Assignee: STMicroelectronics, Inc.Inventors: Oleg Logvinov, Aidan Cully, David Lawrence, Michael J.

Publication number: 20190028853Abstract: Multicast transmissions do not allow for individual receivers to acknowledge that data was received by each receiver in the network. This is not acceptable for isochronous systems that require specific levels of QoS for each device. A multimedia communications protocol supports using multicast transmissions (one-to-many) in multimedia isochronous systems. A transmitter establishes a Multi-ACKed Multicast protocol within which a group of receiving devices can acknowledge the multicast transmission during a multi-acknowledgment period.Type: ApplicationFiled: September 21, 2018Publication date: January 24, 2019Applicant: STMicroelectronics, Inc.Inventors: Oleg Logvinov, Aidan Cully, David Lawrence, Michael Macaluso
