Summary: Results of the Asian Student Cluster CompetitionIn this episode, Dan has just come back from China and reviews the results of the Asian Student Cluster Competition and HPC workshop.For the first time, a non-mainland-Chinese team wins the top spot. Taiwan takes the gold in part by their stellar performance in HPCG benchmark where they achieved 2 TFlops, some 25% better than the 2nd best team. The system was a 5-node cluster with Infiniband FDR interconnect. Other interesting info is shared on various codes and configurations.GPUs and Amdahl's LawDan also mentions that reports from some of the TOP500 sites suggest that GPUs are doing 93-97% of the computation. This sounds very impressive but Shahin points out that since GPUs have hundreds of cores, they should be doing much better, that 93-97% is in fact not as good as it should be at that scale of system and problem size. He is still waiting for some actual utilization data on GPUs too.Catch of the Week Henry:Henry points out many security cameras, offered by several brands but are all manufactured by the same vendor back in China, have big time vulnerabilities so he's staying away from all of them until further notice. Shahin wonders why they are called "security" cameras! P2P Weakness Exposes Millions of IoT DevicesA peer-to-peer (P2P) communications technology built into millions of security cameras and other consumer electronics includes several critical security flaws that expose the devices to eavesdropping, credential theft and remote compromise, new research has found.Shahin:Shahin talks about Jaguar-Land Rover planning to offer a cryptocurrency wallet to reward drivers that participate in providing traffic and other types of data. He likes their catch phrase: zero emission, zero accident, zero congestion. ON THE MONEY: EARN AS YOU DRIVE WITH JAGUAR LAND ROVERDrivers will be able to earn cryptocurrency and make payments on the move using innovative connected car services being tested by Jaguar Land Rover.Dan:Dan laments the confiscation of his external camera battery at the airport in China because the spec label was a little worn off and the authorities could not read it to ascertain its safety despite his willingness to get a note from the airline, etc. Nice expensive battery, but at a medium-sized paperback book, maybe following the rules strictly is not a bad idea.Listen in to hear the full conversation.
