Energy Consumption of MD Calculations on Hybrid and CPU-Only Supercomputers with Air and Immersion Cooling
P. 574–582.
The article presents the energy consumption and efficiency analysis based on the data from three small-size supercomputers installed in JIHT RAS. One system is the air-cooled hybrid supercomputer Desmos with AMD FirePro GPUs and two others are the air-cooled and liquid-cooled segments of the supercomputer Fisher based on AMD Epyc Naples CPUs. To collect data, we implement the same real-time analytics infrastructure on all three supercomputers. We consider classical molecular-dynamics problem as a benchmarking tool. Our results quantify the energy savings that are provided by the GPU-based calculations in compariso with CPU-only calculations and by liquid cooling in comparison with air-cooling. During strong scaling benchmarks, we detect an interesting minimum of energy consumption in the CPU-only case.

This paper examines the problem of clustering consumption patterns for a private household. An ensemble algorithm based on the Wasserstein metric was developed and applied to cluster daily load profiles. The proposed approach allows for identifying typical energy consumption scenarios and interpreting consumer behavior. Results from computational experiments using real data are presented. ...

Most modern monitoring systems, such as environmental monitoring systems, use LoRaWAN (Long Range Wide Area Network) technology. This technology allows to transfer small amounts of data over long distances. In addition, it allows to reduce the number of collisions in such systems due to a wide range of data rates and due to different frequency ...

This paper considers a model of the Internet of Things (IoT) system with a potentially unlimited number of devices. In such systems, a large number of conflicts arises that leads to retransmissions of messages. A large number of retransmissions causes transmitter operation time growth. More transmitting time in turn increases energy consumption and reduce device ...

In this paper, a model of the system with an unlimited number of users is considered. For data transmission in this model, unsourced random access is used. In case of successful transmission, multiple departure of users is carried out. For this system model, some hypotheses are formulated. Based on hypotheses, methods for constructing upper and ...

This article offers a comparison of sociopolitical instability forecasting systems. It compares systematically their efficiency by correlating their predictions for particular years with actual levels of destabilization in the respective years. It is demonstrated that the predictive capacity of those systems dropped dramatically after 2011. This is shown to be connected with the fact that ...

Recently appeared the IEEE 802.11ah standard has introduced a new channel access mechanism, so-called Restricted Access Window (RAW). This mechanism allows an access point (AP) to reduce contention for the channel in overloaded Wi-Fi networks by limiting the number of stations simultaneously accessing the channel. The 802.11ah AP divides all associated stations into groups and ...
