Patent number: 8875162Abstract: Completion interrupts corresponding to I/O requests issued by a virtual machine guest, which runs on a host platform, are virtualized in such a way that I/O completion interrupts to the requesting guest are delivered no faster than it can stably handle them, but, when possible, faster than the nominal speed of a virtual device to which a virtual machine addresses the I/O request. In general, completion events received from the host platform in response to guest I/O requests are examined with respect to time. If enough time has passed that the virtual device would normally have completed the I/O request, then the completion interrupt is delivered to the guest. If the nominal time has not elapsed, however, the invention enqueues and time-stamps the event and delivers it at the earliest of a) the normal maturity time, or b) at a safepoint.Type: GrantFiled: August 9, 2013Date of Patent: October 28, 2014Assignee: VMware, Inc.Inventors: Ole Agesen, Boris Weissman, Keith Adams, Jennifer-Ann M.

Patent number: 8555274Abstract: A plurality of virtual machines (VMs) is established and maintained by virtualization software on one or more physical servers. Desktop management software operates to provide the VMs to remote users as virtualized desktops. The desktop management software includes a connection broker, that allows a remote user to select a type of virtualized desktop and initiate a desktop session. The desktop management software further includes lease management functionality, that ensures users are provided access to a particular virtualized desktop for only a fixed period of time. In addition, the desktop management software provides an administrative console, which allows an administrator to set various parameters, including QoS parameters, and parameters specifying the resources allocated to each user. The desktop management software interacts with lower level software to provide load-balancing functionality, that adjusts the resources provided to each VM based on the needs of the VM.Type: GrantFiled: March 31, 2006Date of Patent: October 8, 2013Assignee: VMware, Inc.Inventors: Puneet Chawla, Jennifer-Ann M.

Patent number: 8141075Abstract: A plurality of virtual machines (VMs) is established and maintained by virtualization software on one or more physical servers. Desktop management software operates to provide the VMs to remote users as virtualized desktops. The desktop management software includes a rule engine that can be used to automate the policies of the organization. The rule engine manages the data center by controlling virtual infrastructure operations, such as power-on, power-off, suspension, and migration operations. The rule engine uses an event-condition-action paradigm, wherein an event causes a virtual infrastructure operation, possibly contingent on a condition. The rule engine provides for time-based scheduling of events in addition to system-based operations, which are triggered by events such as user logon and user logoff. The rule engine may also include the ability to automate the process of changing the properties of the virtual machines in a timely fashion.Type: GrantFiled: May 8, 2006Date of Patent: March 20, 2012Assignee: VMware, Inc.Inventors: Puneet Chawla, Jennifer-Ann M.

Patent number: 6092180Abstract: In a method for scheduling instructions executed in a computer system including a processor and a memory subsystem, pipeline latencies and resource utilization are measured by sampling hardware while the instructions are executing. The instructions are then scheduled according to the measured latencies and resource utilizations using an instruction scheduler.Type: GrantFiled: November 26, 1997Date of Patent: July 18, 2000Assignee: Digital Equipment CorporationInventors: Jennifer-Ann M.

Patent number: 5964867Abstract: A method is provided for optimizing a program by inserting memory prefetch operations in the program executing in a computer system. The computer system includes a processor and a memory. Latencies of instructions of the program are measured by hardware while the instructions are processed by a pipeline of the processor. Memory prefetch instructions are automatically inserted in the program based on the measured latencies to optimize execution of the program. The latencies measure the time from when a load instructions issues a request for data to the memory until the data are available in the processor. A program optimizer uses the measured latencies to estimate the number of cycles that elapse before data of a memory operation are available.Type: GrantFiled: November 26, 1997Date of Patent: October 12, 1999Assignee: Digital Equipment CorporationInventors: Jennifer-Ann M.
