Training for users to access and use the resources of the supercomputer “Avitohol”, September 14, 2020

The forthcoming training is intended for members of the teams working on the NPP “Environmental Protection and Reduction of the Risk of Adverse Events and Disasters” and on the scientific infrastructure “National Geoinformation Center “. The purpose of the training is to engage new users (scientists, students, PhD students) wishing to use computing resources of the supercomputer Avitohol in the implementation of their activities. The training will be conducted remotely, using the Zoom platform, and information about the event will be sent to the emails of registered participants.

The new ranking of the most powerful supercomputers

The new ranking of the most powerful supercomputers in the world was published on June 22 ( The first place is taken by the Japanese supercomputer Fugaku, located at the Riken Center for Computational Science in Japan. Fugaku has 7,299,072 processor cores and performs 415.5 quadrillion operations per second. Top 3 is complemented by the second-ranked supercomputer Summit, located in the United States, which has 2,414,592 processor cores, operations per second are 148.8 quadrillion. In third place is Sierra, also a US-based supercomputer, with estimates of up to 94.6 quadrillion operations per second. The list of the 10 most powerful supercomputers includes 5 supercomputers from the USA, 2 from China, 1 from Italy and 1 from Switzerland.

In the first place for the most energy efficient system of Green500 is ranked MN-3, based on a new server. He set a record of 21.1 gigaflops per watt while performing 1.62 petaflops. The system derives its superior energy efficiency from the MN-Core chip, an accelerator optimized for matrix arithmetic. It is ranked number 395 in the TOP500 list. More information on the various rankings can be found here.

Our colleague Prof. Emanouil Atanassov was awarded with the annual scientific award in Bulgaria in the category “Supercomputing applications and Big Data analysis”

On the holiday of education and culture in Bulgaria on May 24, the awards for significant contribution to the field of science “Pythagoras” were presented. The official ceremony was broadcast on the Bulgarian National Television (BNT1). For the 12th time, the Ministry of Education and Science of Bulgaria presents awards to scientists, research teams and organizations for achievements in the field of science and technology, determined by an authoritative jury composed of previous winners of the award. Guests of the ceremony are Ms. Maria Gabriel, EU Commissioner for Innovation, Research, Culture, Education and Youth, and Mr. Krassimir Valchev, Minister of Education and Science in Bulgaria.

Our colleague, Prof. Emanouil Atanassov, the head of the Department of HPC systems, networks and algorithms at IICT-BAS, was awarded “Pythagoras” in the category “Supercomputing applications and Big Data analysis”. This is his second scientific award. In 2004 he received a “John Atanassoff” honorary diploma from the President of Bulgaria for outstanding contribution in the field of information technology.
