Publication number: 20240089147Abstract: A method includes providing a plurality of processes interconnected by a network, each of the plurality of processes being configured to hold a block of data destined for others of the plurality of processes. A set of data for all-to-all data exchange is received from one or more of the processes. The set of data is configured as a plurality of blocks of data in a matrix as matrix data, the matrix being distributed among the plurality of processes. The matrix data is transposed by changing the position of selected blocks of data of the plurality of blocks of data relative to the other blocks of data of the plurality of the blocks of data, without changing the structure of each of the blocks of data. The transposed matrix data is over the network and is then received, repacked, and conveyed to destination processes.Type: ApplicationFiled: November 19, 2023Publication date: March 14, 2024Inventors: Richard Graham, Lion Levi, Gil Bloch, Daniel Marcovitch, Noam Bloch, Yong Qin, Yaniv Blumenfeld, Eitan Zahavi

Patent number: 9300314Abstract: An arrangement for reading out an analog voltage signal includes a voltage signal input for applying the analog voltage signal thereto, a reference unit configured to generate an analog reference voltage, and a converting unit configured to convert an analog input signal into a digital output signal. To enable online self-calibration of the arrangement, the arrangement includes a superposition unit configured to receive the analog voltage signal and the analog reference voltage. The superposition unit includes a modulation unit configured to generate a modulated reference voltage from the analog reference voltage. The superposition unit is configured to generate a combined analog signal by superimposing the modulated reference voltage onto the analog voltage signal, and to forward the combined analog signal to the converting unit.Type: GrantFiled: October 16, 2013Date of Patent: March 29, 2016Assignee: ABB TECHNOLOGY AGInventors: Joris Pascal, Richard Bloch
