This is LUMI powerful world supercomputers aims to prevent pandemics and promote the ecological transition - The world of technology is moving by leaps and bounds, so getting the key device at the right time could change everything.

Proof of this is Hewlett Packard Enterprise (HPE), which after a long process has finally been the winner of the competition to develop a supercomputer called LUMI, receiving 160 million dollars for its manufacture at the Finnish IT Center in the Finnish city of Kajaani.

LUMI will be between 5 supercomputers the world's fastest, thanks to the joint effort of 10 european countries, Belgium, the Czech Republic, Denmark, Estonia, Finland, Iceland, Norway, Poland, Sweden and Switzerland, and the Company Common EuroHPC, whose purpose is to give a step further in terms of research, employment, competitiveness and transition to green.

"We are committed to supporting EuroHPC JU to seize opportunities in next-generation supercomputing and strengthen science R & D, drive innovation and unlock economic growth," says Peter Ungaro, vice president and general manager, High Performance Computing (HPC).

With HPE Cray EX servers with AMD Epyc processors and high-performance AMD Instinct graphics cards, LUMI is expected to reach a theoretical peak performance of no more than 550 petaflops. A higher number than the 513 of the fastest computer in the world to date, Fugaku, coming from Japan.

As for its dimensions, it will occupy an area of 150 square meters, the same as a tennis court, and will weigh about 150 tons.

Slingshot for networking, a Cray ClusterStor E1000 storage system from HPE and also promises in the field of artificial intelligence, climate and pharmaceutical.

Supercomputers are essential in the fight against pandemics such as that of the coronavirus, since they allow to create simulations of studies related to vaccine research for example, in order to prevent further infections.

In this way, LUMI could streamline these simulations and overcome many of the most complicated scientific challenges, providing speed and efficiency.

Another point to note of this future supercomputer is environmental sustainability, as it will work with 100% renewable Vattenfall hydroelectric power.

In addition, the waste heat produced by LUMI will be used to heat 20% of households in the urban area of Kajaani, thus following the Digital and Green Deal policies of the European Commission.

This supercomputer is expected to be fully available from mid-2021 through a consortium between the European countries involved.

In addition, HPE intends to warm up engines with the pre-opening of a center of excellence dedicated to high-performance computing in terms of research, as well as increasing its production of liquid-cooled supercomputers Cray EX and Apollo systems.

LUMI is not only ready to revolutionize the world of computers, it will be a great opportunity for innovation in such essential sectors as health or weather forecasting, according to the Executive Director of the EuroHPC Joint Undertaking Anders Dam Jensen.

It could be the definitive device to fight future pandemics and even the current coronavirus crisis.

Research reveals exactly how effective masks are against coronavirus in enclosed spaces

pressure on how to maintain the economy while ensuring people's safety, much research is focusing on trying to determine the risk of contracting the virus in enclosed spaces and how to better protect yourself.

In a study published in Physics of Fluids, scientists Amit Agrawal and Rajneesh Bhardwaj have estimated how much a mask can reduce the spread of a cough-dispersed drop.

Research reveals that the first 5 to 8 seconds after coughing are the ones that matter to suspend the droplets exhaled in the air and, consequently, for the spread of the disease. After that time, the cough cloud typically begins to disperse.

Scientists have found that the volume of the cloud without a mask is about 7 times greater than with a surgical mask and 23 times greater than with an N95 mask.

"We found that anything that reduces the distance traveled by the cloud, such as a mask, a handkerchief or coughing in an elbow, should greatly reduce the region over which the drops are dispersed when coughing and therefore the chances of infection," says Rajneesh Bhardwaj.

In addition, the researchers assure that their formula will be useful in determining the maximum number of people who can be housed in a single room and the minimum rate at which air should circulate indoors to reduce the risk of infection.
