20100037081 | Method and Apparatus for Maintaining Time in a Computer System - A computer system is arranged with a circular buffer that includes a piecewise linear map from a high-resolution counter arranged to maintain International Atomic Time. The piecewise linear map includes a current leg that is currently being used and also a future leg that will be used in the future. The future leg is computed while the current leg is still being used. | 02-11-2010 |
20100100762 | BACKUP POWER SOURCE USED IN INDICATING THAT SERVER MAY LEAVE NETWORK - A server of a network of servers determines that its power source is failing. In response, the server communicates to one or more other servers of this network that it is leaving the network. This communication is powered by another power source. | 04-22-2010 |
20100185889 | CHANNEL SUBSYSTEM SERVER TIME PROTOCOL COMMANDS - A protocol for communicating with the timing facility used in a data processing network to provide synchronization is provided via the execution of a machine instruction that accepts a plurality of commands. The interaction is provided through the use of message request blocks and their associated message response blocks. In this way timing parameters may be determined, modified and communicated. This makes it much easier for multiple servers or nodes in a data processing network to exist as a coordinated timing network and to thus more cooperatively operate on the larger yet identical data files. | 07-22-2010 |
20100223317 | SERVER TIME PROTOCOL MESSAGES AND METHODS - Server time protocol (STP) messages and methods of exchange thereof are provided for facilitating synchronization of processing units of a timing network. The STP messages include exchange time parameters (XTP) commands and responses, and STP control (STC) commands and responses. XTP message exchange processing includes: generating an XTP message command at a first processing unit including a command transmit timestamp field set by the first processing unit and a command receive timestamp field which is unset by the first processing unit; transmitting the XTP message command to a second processing unit; setting the command receive timestamp field in the XTP command with the time the XTP command is received at the second processing unit; and generating an XTP message response at the second processing unit, the message response including the command transmit timestamp set by the first processing unit and the command receive timestamp set by the second processing unit. | 09-02-2010 |
20110106968 | Techniques For Improved Clock Offset Measuring - In an exemplary aspect, method, apparatus, and program products are disclosed suitable for clock offset determination. One method includes performing a number of exchanges of at least single bytes with another network node, where values of the single bytes are different for the exchanges. The method also includes capturing and storing timestamps for each of the number of exchanges performed on the network node. A second method includes capturing and saving arrival timestamps for each of a number of timing messages in a set of timing messages received from another network node. This second method also includes sending the timestamps to at least the another node in response to completion of the set of timing messages. | 05-05-2011 |

The interaction is provided through the use of message request blocks and their associated message response blocks. In this way timing parameters may be determined, modified and communicated. This makes it much easier for multiple servers or nodes in a data processing network to exist as a coordinated timing network and to thus more cooperatively operate on the larger yet identical data files. | 09-26-2013 |
20130262424 | DATABASE SYSTEM TRANSACTION MANAGEMENT - Systems, methods, and products for database system transaction management are provided herein. One aspect provides for annotating via a computing device at least one data object residing on the computing device utilizing at least one transaction tag, the at least one transaction tag being configured to indicate a status of an associated data object; processing at least one database transaction utilizing a transactional memory process, wherein access to the at least one data object is determined based on the status of the at least one data object; and updating the status of the at least one data object responsive to an attempted access of the at least one data object by the at least one database transaction. Other embodiments and aspects are also described herein. | 10-03-2013 |
20140188962 | Executing Perform Floating Point Operation Instructions - A perform floating-point operation instruction is executed specifying a Test (T) bit of general register 0, if the T bit is ‘1’ the execution sets a condition code value indicating whether a specified conversion function is installed, if the T bit is ‘0’ the execution stores a result of a specified floating-point conversion function in general register 0 and sets a condition code value. | 07-03-2014 |
20140282583 | DYNAMIC MEMORY MANAGEMENT WITH THREAD LOCAL STORAGE USAGE - Methods and arrangements for dynamic memory management. Data are accepted for thread local storage, and memory usage is monitored in thread local storage. A memory block is allocated to thread local storage for storing accepted data, based on the monitored memory usage. Other variants and embodiments are broadly contemplated herein. | 09-18-2014 |
