INSIGHT Whither Supercomputing? The state of global supercomputing in five charts By CIO&Leader A Every six months—in May and November every year—Top500.org, a site tracking supercomputers, comes out with the list of the world’s 500 fastest. The list provides data on the sites where they are hosted, their theoretical and achieved performance, their chitecture, their manufacturers, and a number of other data points. Analysis of the Top500.org data provides excellent insight into the state of supercomputing globally at any point of time. The insights presented here are based on the data presented in the lasts—November 2017— list that also happens to be the 50th list since its beginning. Our insights are drawn from analysis of the Top500.org data for last 10 years—From November 2007 to November 2017. 20 CIO&LEADER | December 2017
Insight Measuring the Speed of Speed How fast is today’s fastest supercomputer? According to November 2017 Top 500 list, it is 93 petaFLOPS—that is 93 million billion floating point operations per second. This is 200 times faster than the fastest supercomputer in November 2007 and 1.6 million times faster than the fastest supercomputer in June 1993, when the list made its debut. The Acceleration How fast have been the fastest (all figures in TFLOPs/second) 33862.7 33862.7 93014.6 478.2 1759 10510 Nov_07 Nov_09 Nov_11 Nov_13 Nov_15 Nov_17 Global Power Shift Like in many other things in business and economy, in supercomputing too, the action has shifted from America and Europe to Asia Pacific. The Chinese Invasion Supercomputing is the latest area where China overthrows the US from top even as India's presence is further marginalized 283 144 10 4 9 Nov_07 Nov_09 Nov_11 Nov_13 Nov_15 Nov_17 China US India Power of the Cluster In terms of the architecture, there is a clear shift to clusterbased supercomputing. Almost nine out of ten Top500 supercomputing sites are cluster-based. The Definite Shift to Clusters Cluster MRP 202 The Asian Edge Supercomputing power too shifts to Asia, driven by China; India's rise could push it further 289 287 274 277 212 109 149 93 The Manufacturers’ Story While Cray still remains the supercomputing company, with shrinking share of MPP architecture, Cray’s share in Top 500 is coming down, even though it still accounts for more than one third of Top 50 sites. Lenovo and a host of Chinese manufacturers show up on the radar, thanks to China’s rise in supercomputer usage. 103 102 150 152 257 179 122 121 60 60 Manufacturer's Share Nov_07 Nov_09 Nov_11 Nov_13 Nov_15 Nov_17 Lenovo completes China story Asia -Oceania Europe Americas China is the New Supercomputing Superpower The big rise of Asia in the supercomputing scene is almost entirely because of the rise of China—and despite the fall of other Asian contenders like Japan and India. In fact, it is a big shift that happened in the latest Top 500 list. For the first time, China replaced the US as the top supercomputing country accounting for more Top500 supercomputer sites than the US. India has been reduced to a marginal player with just four of the Top500 fastest sites present in the country. That is a drop from 12 such sites that it had just four years back. 2% 9% 2% 24% 3% 14% 3% 20% 4% 4% 4% 4% Top 50 8% 10% 4% 10% 11% 11% 36% 16% HPE Lenovo Inspur Cray Inc.
