New AI supercomputer will help create the largest-ever 3D map of the universe

 Nvidia launches new supercomputer with monster AI performance. Perlmutter could complete tasks in days that would normally take months.

 The newest big-name supercomputer might help solve some of astrophysics' most important questions. Nvidia has fired up a new supercomputer said to be the fastest in the world for AI workloads at the National Energy Research Scientific Computer Center (NERSC) in California. The National Energy Research Scientific Computing Center has officially dedicated Perlmutter, billed as one of the fastest supercomputers for AI, and it will start by helping to build the largest-ever 3D map of the visible universe to study the dark energy accelerating the cosmos' expansion.

 The supercomputer is named after astrophysicist Saul Perlmutter and will initially be tasked with building the most ambitious 3D map of the universe ever seen, utilizing the 6,000+ Nvidia A100 Tensor Core GPUs on board.

In its current state, Perlmutter is capable of delivering almost four exaFLOPS of AI performance, which Nvidia says makes it “the fastest system on the planet on 16- and 32-bit mixed-precision math AI uses”. Its performance will be bolstered further as part of “phase two”, with the introduction of a second tranche of CPU cores.

FEATURES OF PERLMUTTER:

lPerlmutter includes 1,536 nodes that each have a 64-core Epyc 7763 processor and four NVIDIA A100 GPUs

l A system with almost four exaflops of performance (plus 35 petabytes of storage) when handling AI tasks, and dramatically reduced calculation times.

lA second phase due later in 2021 will add 3,072 CPU-only nodes that each have dual Epyc 7763 chips.

 The map isn't the only project on deck. Perlmutter will also study atomic interactions to foster clean energy tech like biofuels . Once the system is complete, it is expected to fall within the top five supercomputers in the Top 500 rankings, which assesses overall performance using the High Performance Linpack (HPL) benchmark.

Unhackable Internet

  W hy it matters?   The internet is increasingly vulnerable to hacking; a quantum one would be unhackable. Quantum Computing    A quantum internet could be used to send unhackable messages, improve the accuracy of GPS, and enable cloud-based quantum computing. For more than twenty years, dreams of creating such a the quantum network have remained out of reach in large part because of the difficulty to send quantum signals across large distances without loss.   Now, Harvard and MIT researchers have found a way to correct for signal loss with a prototype quantum node that can catch, store and entangle bits of quantum information. The research is the missing link towards a practical quantum internet and a major step forward in the development of long-distance quantum networks.   The U.S Department of Energy (DoE) explains how a quantum link will make it happen through two quantum phenomenon: the first is quantum entanglement, where two-particle ...

Impact of Social Media on Business

Watch out for that bird! Imagine you are skydiving, you are visiting one of the most beautiful countries in the world and you want to share that experience with your loved ones and friends. Why not send a postcard? Oh wait, you’re already back from the trip by the time that postcard has reached, or it got lost in the mail. If only there was an alternative. This isn’t 1990. You have a platter of platforms to share your adventure. Webster’s dictionary defines social media as-“ forms of electronic communication (such as websites for social networking and microblogging) through which users create online communities to share information, ideas, personal messages, and other content (such as videos).”In simple words, social media, are various public platforms where people can share their views, stories, etc. with the help of various mediums. Starting with websites such as MySpace, Orkut, and Facebook, etc. it is now estimated that there are about 200 social media websites in ...

Pegasus Spyware: Flying Through The Air

 Hundreds of millions of people can't imagine life without their smartphones. Almost every aspect of their daily lives, from the most mundane to the most intimate, is within easy reach and hearing distance of their smartphones. Only few people realize that their phones may be used as surveillance devices, with someone hundreds of miles away secretly extracting their messages, photographs, and location while also activating their microphone and recording them in real time. Such capabilities are present in Pegasus, a spyware produced by NSO Group, an Israeli maker of mass surveillance weapons. What is Pegasus? Pegasus is a hacking software – or spyware – that is developed, marketed and licensed to governments around the world by the Israeli company NSO Group. It has the capability to infect billions of phones using either iOS or Android operating systems. The spyware is named after Pegasus, the white winged horse from Greek mythology. It is named so because it "flies through the...
