Filed:

Dec 16, 1999

Appl. No.:

09/461729

Inventors:

Rajesh R. Shah - Portland OR
Robert J. Woodruff - Banks OR

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06F 132

US Classification:

713300, 713323

Abstract:

A cluster operating in accordance with an integrating operating system independent power management with operating system directed power management includes a group of hosts connected together by a cluster interconnection fabric. A cluster administrator is connected to the group of hosts via the fabric and the cluster administrator includes a cluster power manager. A group of input/output units are connected to the group of hosts and the cluster interconnection fabric. Each of the hosts includes a controller element and an operating system power manager and input/output controller device driver stack. The cluster administrator transmits a request to the controller element of one of the hosts via the fabric and receives a reply therefrom and transmits a command. The controller element transmits the command to the operating system power manager and the input/output controller device driver stack of its host and transmits a command completion acknowledgment to the cluster power manager. The technique allows a cluster administrator to power manager fabric attached hosts and input/output controllers regardless of which host currently owns the controller.

International Classification:

G06F 300

US Classification:

709221, 709226, 714 4, 710 19

Abstract:

I/O resources are allocated to one or more hosts in a network cluster. Each host stores a cluster resource table (CRT) that identifies the configuration and allocation of I/O resources within its cluster. Each host includes an I/O resource management agent (RMA) within the operating system. A hosts RMA obtains a list of all hosts and I/O units and their network addresses from the fabric services. The RMA then queries each host to obtain at least a portion of the CRTs of each of the hosts in the cluster. The RMA replaces its local CRT with the most current version of the CRT (e. g. , based on a time and date stamp or version number of each CRT). The hosts RMA then queries each I/O unit to identify the I/O controllers and their controller number in the cluster. The RMA then queries each I/O controller in the cluster to identify the I/O devices in the cluster. The RMA then updates its CRT based on this information.

International Classification:

H04L 12/28

US Classification:

370392

Abstract:

Remote direct memory access over a network uses a constrained usage model. In one embodiment, a method of accessing memory on a network comprises a first node of the network generating a remote direct memory access request to remotely access application-level memory on a second node of the network. The first node sends the request in a packet over the network to the second node, the sending being performed in accordance with a constrained usage model. In a further embodiment, constrained usage model comprises sending the packet in an Ethernet protocol packet over an Ethernet network, the Ethernet protocol packet having a OSI layer two header, but not a layer three header.

International Classification:

G06F015/16

US Classification:

709200000

Abstract:

A technique includes providing a signal to a communication link to communicate a data value across the communication link. At least one wavelength is selectively introduced to the signal. The wavelength(s) identify the data value.

International Classification:

G06F 9/50
G06F 9/455
G06F 15/173
G06F 9/54

Abstract:

In an embodiment, a method is provided. In an embodiment, the method includes implementing a virtual remote direct memory access (RDMA) component in a virtualization layer on the computer system, the virtual RDMA component having an interface implementing RDMA semantics. An RDMA send request from a send queue associated with a first application running on the first VM is read using the virtual RDMA component, the RDMA send request referencing a send buffer in an application memory space for the first application. The virtual RDMA component then copies or transfers a message in the send buffer to a receive buffer in the second VM. A host computing system configured to implement the method and instructions configured to be executed on a host computing system is also provided.

Abstract:

In an embodiment, a method is provided. In an embodiment, the method provides determining that a message has been placed in a send buffer; and transferring the message to an application on a second virtual machine by bypassing use of an operating system to process the message by directly placing the message in an application memory space from which the application can retrieve the message.

Abstract:

Methods, apparatus, and systems for leveraging an offload programming model for local checkpoints. Compute entities in a computing environment are implemented as one or more sources and a larger number of sinks. A job dispatcher dispatches jobs comprising executable code to the source(s), and the execution of the job code is managed by the source(s). Code sections in the job code designated for offload are offloaded to the sinks by creating offload context information. In conjunction with each offload, an offload object is generated and written to storage. The offloaded code sections are executed by the sinks, which return result data to the source, e.g., via a direct write to a memory buffer specified in the offload context information. The health of the sinks is monitored to detect failures, and upon a failure the source retrieves the offload object corresponding to the code section offloaded to the failed sink, regenerates the offload context information for the code section and sends this to another sink for execution.
