With up to 16 NVIDIA Tesla K80 GPUs, P2 instances are the most powerful GPU instances available in the cloud. "The massive parallel floating point performance of Amazon EC2 P2 instances, combined with up to 64 vCPUs and 732 GB host memory, will enable customers to realize results faster and process larger datasets than was previously possible." P2 instances allow customers to build and deploy compute-intensive applications using the CUDA parallel computing platform or the OpenCL framework without up-front capital investments. To offer the best performance for these high performance computing applications, the largest P2 instance offers 16 GPUs with a combined 192 Gigabytes (GB) of video memory, 40,000 parallel processing cores, 70 teraflops of single precision floating point performance, over 23 teraflops of double precision floating point performance, and GPUDirect technology for higher bandwidth and lower latency peer-to-peer communication between GPUs. P2 instances also feature up to 732 GB of host memory, up to 64 vCPUs using custom Intel Xeon E5-2686 v4 (Broadwell) processors, dedicated network capacity for I/O operation, and enhanced networking through the Amazon EC2 Elastic Network Adaptor.

A coroner says a 6-year-old boy has died days after he was critically wounded in a school shooting in South Carolina. Anderson County Coroner Greg Shore said Jacob Hall died about 1 p.m. Saturday. Jacob had been fighting for his life at a hospital since the shooting Wednesday at Townville Elementary School. A bullet struck Hall in a main artery in his leg, causing massive bleeding. Authorities say another student and a first-grade teacher were also shot when a 14-year-old boy opened fire on a playground.

A Somali police officer says a car bomb blew up at the entrance of a restaurant in the Somali capital of Mogadishu, killing two people. Mohamed Hussein said the blast Saturday occurred at the Blue Sky restaurant close to the presidential palace. There was no immediate claim of responsibility for the bombing, but the Islamic extremist group of Shabab often carries out such attacks. Shabab, Al Qaeda's East African affiliate, is fighting to impose a strict version of Islam in this Horn of Africa nation. Despite losing a lot of ground in recent years, the extremist group continues to carry out lethal attacks in many parts of the country, especially in the capital.

Analysis The invitation for Google's latest cloud sales pitch, dubbed "Horizon" because the company has already had its way with "Atmosphere", on Thursday directed attendees to The Mint. As San Franciscans know, and Google Search advises to those in the area, The Mint is a karaoke bar, not far from the San Francisco Mint, which began churning out legal tender in 1937. The actual location of the affair turned out to be the Old US Mint, a classical edifice that, through the marketing value of its facade, now helps companies advance their efforts to print money. The cloud, for Google, represents something of a climb. As of August, Google trailed Amazon Web Services, Microsoft Azure, and IBM in public infrastructure-as-a-service marketshare, by the measure of Synergy Research Group.

Alphabet Inc's Google has renamed its business-to-business cloud computing brand and enhanced some enterprise applications using artificial intelligence, the company's latest gambit to better compete with Amazon.com and Microsoft Corp. in the lucrative cloud business. Discussing the rebranded Google Cloud, Diane Greene, senior vice president of Google's enterprise business, said the company has made good progress courting customers and improving its technology. Cloud computing uses remote internet servers to store, manage and process data, and Google offers a range of apps like word processing and email, as well as the ability to host data and offer resources for developers. The new name replaces the Google for Work brand. "We are closing the gap incredibly fast" with competitors, Greene, a former CEO of VMware who joined Google last year to ramp up its cloud business, told experts and journalists at an event.

Russia has warned the United States against carrying out any attacks on Syrian government forces, saying it would have repercussions across the Middle East. Russian news agencies quoted Foreign Ministry spokeswoman Maria Zakharova as saying that a U.S. intervention against the Syrian army "will lead to terrible, tectonic consequences not only on the territory of this country but also in the region on the whole." She says regime change in Syria would create a vacuum that would be "quickly filled" by "terrorists of all stripes." U.S.-Russian tensions over Syria have escalated since the breakdown of a cease-fire last month, with each side blaming the other for its failure. Syrian government forces backed by Russian warplanes have launched a major onslaught on rebel-held parts of the northern city of Aleppo.

Swiss researchers have completed a study documenting how alcoholic beverages function as a "social lubricant." Was formal research really needed to establish that alcohol "facilitates sexual disinhibition" leading to hook-ups? As if we baby boomers hadn't already made that connection decades ago. Perhaps the researchers weren't familiar with the wisdom (and wit) of mid-20th century poet Ogden Nash, who famously observed, "Candy is dandy, but liquor is quicker." To the editor: How can I get on the research gravy train as illustrated by this study whose "researchers concluded that alcohol's role as a social lubricant can be traced to its ability to facilitate'sexual disinhibition?' " Revelation!

With Congress opening the way for Sept. 11 families to sue Saudi Arabia, victims' families are focusing on an unproven theory that a Saudi consular official in Los Angeles and a Saudi intelligence operative in San Diego directly assisted two of the 19 hijackers. The alleged Southern California connection is the key to showing that Saudi Arabia financed Muslim extremists who played a direct role in supporting some of the hijackers, according to lawyers for the families of those killed in the 2001 terrorist attacks. The families contend that lower-level Saudi operatives in Southern California helped find housing for the two hijackers, both Saudi citizens, months before they muscled their way into the cockpit of an American Airlines passenger jet that smashed into the north side of the Pentagon. If a pending lawsuit is allowed to proceed, the families hope to find the evidence in thousands of classified FBI, CIA and Treasury Department documents that could be made public as part of discovery in federal court. Saudi Arabia has repeatedly denied any direct or indirect support for Al Qaeda, the terrorist group that carried out the attacks, or any foreknowledge or involvement in the attacks that killed nearly 3,000 people in New York, Washington and Pennsylvania.

At Experian DataLabs in San Diego, a team of scientists is thwarting bad guys with math. A top-five U.S. credit card issuer recently dumped about 6 billion transaction records on Experian DataLabs to see if its machine-learning mathematical formulas could do a better job of rooting out credit card fraud than the bank's existing system. Experian scientists used neuro-embedding/natural language processing techniques to understand the "syntax" of the credit card data, computer scientist Honghao Shan said. "We thought we had figured it out and went back to them," said Eric Haller, head of Experian DataLabs. "They said, 'How did you do that?' … It turns out we reduced their false positives by half."

We never need to go far for a little -- or a lot -- of Beethoven in our concert halls. The Los Angeles Philharmonic (with help from the Simón Bolívar Symphony Orchestra of Venezuela) wasn't kidding when it began its season last year with Gustavo Dudamel conducting all nine Beethoven symphonies by calling the festival "Immortal Beethoven." Last weekend, Los Angeles Chamber Orchestra opened its season with Beethoven's Seventh. Next week, Esa-Pekka Salonen begins a West Coast tour with his London orchestra, the Philharmonia, playing Beethoven's "Eroica" in Costa Mesa, Northridge and Santa Barbara. Thursday night, the L.A. Phil did it again, opening another season with a Beethoven program at Walt Disney Concert Hall, the orchestra living up to its venturesome reputation by including John Adams in its definition of Beethoven.
