Green computing is currently a popular trend and need among European and world computing centers. The basic assumption is to use the existing computing infrastructure in such a way to minimize electricity consumption without significantly affecting the efficiency of calculations and the quality level of the services provided.
CI TASK, together with the ETI Faculty, actively participates in research and development (R&D) of modern technologies enabling the optimization of the use of electricity in large-scale calculations. The following project goals are currently being implemented:
- Methods development and software development for multi-criteria optimization (energy, performance) for High Performance Computing (HPC) for CPU and GPU computing units, using hardware power-cap mechanisms.
- Construction of electricity consumption models for the analysis of large-scale data sets (Big Data), using multi-node computer systems, with particular emphasis on modern data processing platforms (e.g. Apache Spark), using the Green Lab, created at CI TASK.
A special laboratory was established to achieve the objectives of the Green Lab project. It consists of 16 computing nodes, located in a server racks, connected by an Ethernet 1Gb/s network. During computational experiments, electricity consumption is monitored on several levels: power strips (PDUs), power supplies and directly processors (CPUs), and memory (RAM). The figure below shows a diagram of the laboratory:
Internal project, leaded since 2017 with the participation of the ETI Department. Estimated time perspective: 5 years. The costs include the maintenance of the GreenLab laboratory (CI TASK) and expenses related to the publication of test results. Implementation from own funds.
