Apparatus And Method For Managing Work And Completion Queues Using Head And Tail Pointers

US Patent:
6725296, Apr 20, 2004
Filed:
Jul 26, 2001
Appl. No.:
09/915663
Inventors:
David F. Craddock - New Paltz NY
Thomas Anthony Gregg - Highland NY
Ian David Judd - Winchester, GB
Gregory Francis Pfister - Austin TX
Renato John Recio - Austin TX
Donald William Schmidt - Stone Ridge NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 300
US Classification:
710 52, 710 57, 710112
Abstract:
An apparatus and method for managing work and completion queues using head and tail circular pointers. With the apparatus and method, queue head and tail pointers are maintained in the channel interface and the host channel adapter. The head and tail pointers in the host channel adapter include a queue pointer table index and a queue page index for identifying a position within the queue. For work queues, the tail pointer in the channel interface is used to identify a next position where a work queue entry may be written. The head pointer in the channel interface is used only to determine whether the work queue is full or not. The head pointer in the host channel adapter is used to identify a next work queue entry for processing by the host channel adapter. The tail pointer in the host channel adapter is used by the host channel adapter to determine if the queue is empty. For completion queues, the head pointer in the channel interface is used to identify a next completion queue entry to be processed.

Method And System For Reliably Defining And Determining Timeout Values In Unreliable Datagrams

US Patent:
6748559, Jun 8, 2004
Filed:
Oct 19, 2000
Appl. No.:
09/692349
Inventors:
Gregory Francis Pfister - Austin TX
Giles Roger Frazier - Austin TX
Danny Marvin Neal - Round Rock TX
Steven Mark Thurber - Austin TX
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 1100
US Classification:
714 56, 714 4, 709226
Abstract:
A method for managing allocation of network resources within the distributed computer system is provided. Specifically, the network traversal time and the end node response time for requests and/or packets being routed in a switch-connected system area network are utilized to determine the total round trip time for completion of the particular network operation. The sum of the timeout values for all switches that participate in routing the request from a requester (source) to the receptor node (target) is provided to the requesters channel adapter (CA). The time-out values are provided by the switch manufacturer and are sent to a network Subnet Manager (SM) via SM packets (SMP). The timeout values added together represent the SubnetTimeout. The time-out value of the target channel adapter (CA), the ResponseTime, is also provided to the requester. The requester then utilizes one of two timeout equations to calculate the overall response time required for the request to be completed.

Method And Apparatus For Pausing A Send Queue Without Causing Sympathy Errors

US Patent:
6766467, Jul 20, 2004
Filed:
Oct 19, 2000
Appl. No.:
09/692340
Inventors:
Danny Marvin Neal - Round Rock TX
Gregory Michael Nordstrom - Pine Island MN
Gregory Francis Pfister - Austin TX
Renato John Recio - Austin TX
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 1100
US Classification:
714 5
Abstract:
A method and apparatus for pausing a send queue while preventing sympathy error from propagating through a SAN fabric system is provided. The method and apparatus place a send work queue in an error state, i. e. pauses the send work queue, when a reliable data error occurs in the send work queue but does not place any other work queues in an error state. In this way, the send queue experiencing the error is not able to send any further messages until error recovery is performed. However, other work queues continue to be able to send and/or receive messages. Once error recovery is performed, the send work queue that was placed in the error state is returned to a working state and is able to continue to send messages. In addition, the send queue that was in the error state will send the messages that it attempted to send at the time of the error. The messages sent will continue from a last known point at which the send work queue was operating properly.

Infiniband Work And Completion Queue Management Via Head And Tail Circular Buffers With Indirect Work Queue Entries

US Patent:
6789143, Sep 7, 2004
Filed:
Sep 24, 2001
Appl. No.:
09/961922
Inventors:
David F. Craddock - New Paltz NY
Thomas Anthony Gregg - Highland NY
Ian David Judd - Winchester, GB
Gregory Francis Pfister - Austin TX
Renato John Recio - Austin TX
Donald William Schmidt - Stone Ridge NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 1300
US Classification:
710 54, 710 52, 710 57, 711147, 711153, 711173
Abstract:
A distributed computing system having (host and I/O) end nodes, switches, routers, and links interconnecting these components is provided. The end nodes use send and receive queue pairs to transmit and receive messages. The end nodes use completion queues to inform the end user when a message has been completely sent or received and whether an error occurred during the message transmission or reception process. A mechanism implements these queue pairs and completion queues in hardware. A mechanism for controlling the transfer of work requests from the consumer to the CA hardware and work completions from the CA hardware to the consumer using head and tail pointers that reference circular buffers is also provided. The QPs and CQs do not contain Work Queue Entries and Completion Queue Entries respectively, but instead contain references to these entries. This allows them to be efficient and constant in size, while the Work Queue Entries and Completion Queue Entries themselves can vary in size, for example to include a variable number of data segments.

Open Format Storage Subsystem Apparatus And Method

US Patent:
6829685, Dec 7, 2004
Filed:
Nov 15, 2001
Appl. No.:
09/999143
Inventors:
Danny Marvin Neal - Round Rock TX
Gregory Francis Pfister - Austin TX
Renato John Recio - Austin TX
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 1200
US Classification:
711153
Abstract:
An open format storage subsystem and method are provided. The storage subsystem and method include at least one host endnode, at least one processing unit endnode, and at least one storage endnode. These endnodes are partitioned according to partition tables assigned to the ports of the endnodes and partition keys assigned to queue pairs of the ports. Based on these partition keys, partitions in the storage subsystem are designated. In this way, certain endnodes may be designated as being able to communicate with only certain other ones of the endnodes. Because of the partitioning mechanism of the present invention, an open format storage subsystem is formulated such that the types of endnodes in the storage subsystem are not limited to vendor specific units. This enhances the ability to add and remove units from the storage subsystem by removing the limitations typically found in closed storage subsystems.

Inventors:
Gregory Francis Pfister - Austin TX
Renato John Recio - Austin TX
Noshir Cavas Wadia - Morgan Hill CA
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 1300
US Classification:
711144, 711118, 711119, 711113, 711141, 711156, 709200, 709201, 709216
Abstract:
A method, apparatus, and computer implemented instructions for managing a plurality of caches of data, wherein the data processing system includes a plurality of independent computers. In response to initiating a read operation to read data on a data block, an indication is posted on a directory of data blocks identifying the computer that now holds a copy of that block and a location in the memory of that computer where a flag associated with that block is held. Then in response to initiating a write operation on that data block, messages are sent to all the computers holding that block which resets the said flag, thus informing each computer that the data in that block is no longer valid. These messages are sent using means that perform that flag reset without, in the preferred embodiment, any overhead of interruption of processing on the computers where the flags reside.

Method And System For Choosing A Queue Protection Key That Is Tamper-Proof From An Application

US Patent:
6851059, Feb 1, 2005
Filed:
Oct 19, 2000
Appl. No.:
09/692353
Inventors:
Gregory Francis Pfister - Austin TX, US
Renato John Recio - Austin TX, US
Danny Marvin Neal - Round Rock TX, US
Steven Mark Thurber - Austin TX, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H04L 900
US Classification:
713200, 713152, 713164, 713189, 713201, 380280, 710 39, 710 40, 711154
Abstract:
A method for enabling a Q_key that is tamper proof from applications on a distributed computer system to protect selected network operations is provided. Applications and an operating system (OS) execute on the end nodes and each may access various network resources. In the invention, the network resources are configured for selective access by particular applications or OS. In a preferred embodiment, a control bit of a Q_key, which allows applications to authenticate their use of particular communication resources, i. e. , the send and receive queues, is reserved and utilized to signal whether a particular application is allowed access to the resources. Setting the control bit to 0 allows the Q_key to be set by an application directly. When the control bit is set to 1, the Q_key cannot be set by an application and can only be set using a privileged operation performed only by the OS.

US Patent:
6898638, May 24, 2005
Filed:
Jan 11, 2001
Appl. No.:
09/758737
Inventors:
Giles Roger Frazier - Austin TX, US
Gregory Francis Pfister - Austin TX, US
Renato John Recio - Austin TX, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F013/00
US Classification:
709232
Abstract:
A method, apparatus, and computer implemented instructions for transferring data. A request is sent by a requester to a responder. The request includes an amount of available processing space at the requestor. When the request is received from the responder, data is identified using the request. The data is placed into a plurality of subsequences of data packets for transfer to the requester, wherein each packet within the set of subsequences hold data in amount less than or equal to the amount of available space. These subsequences are then sent to the requestor one subsequence at a time. A new subsequence is sent each time the available processing space at the requester becomes free to process data from another subsequence. The requestor receives a subsequence from the plurality of subsequences in response to the request each time the amount of available processing space is free, wherein data within each of the set of subsequences fits within the amount of available processing space.
