If the high-performance computing often idle how to recover the investmentMore practical problem is that the world's Top500 supercomputers already have more than 80% of the machines are in use quad-core processors, and even 6% of the machine using a six-core and above processors. Multicore technology has long been a trend in high-performance computing.The popularity of multi-core processors bring the most immediate difficulty is the parallel software and parallel computing large demand for talent. In China, the degree of multi-core enough. Today, parallel programming talent really knows very little, a lot of software can only be used 16-core following scale, such as the Shanghai Supercomputer using 16-core operations accounted for less than 60%, can use the software to more than 32 cores is rare .High performance computing and science have been tightly linked with economic status, IDC vice president Steve Conway computing technology has said, The investment for the next generation of HPC systems will be very alarming. Need to invest in these areas - system , storage, software and skilled engineers. China Petroleum Exploration and Development Research Institute, Nanjing Institute of Petroleum Geophysical engineer Zhao improvement for this problem that a lot of people currently in Nanjing are transferred from other professionals, no one specifically to do this (development). He jokingly says that today's schools seem reluctant to teach Linux systems, but prefer to teach Windows, but in most of the high-performance computing systems is based on Linux, and like oil, earthquakes, etc. For some of these industries and geography, chemistry and other professional knowledge are higher, it is difficult to find professional counterparts particular talents.Commenting on the popular CPU GPU heterogeneous mode, Zhao also said to improve that not enough developers model of development is also a hindrance.In the past decade, HPC system provider shrinking the number of European players are increasingly scarce, however, Chinese manufacturers are facing continuous tight European manufacturers in the petaflop war, Europe and the United States are also keen on Japan, China to maintain the same pace, will also for the local HPC system resources continuing to invest.This is not the biggest problem, supercomputers life of the system in about five years or so, according to the TOP500 statistics, for any set of systems, fell from first place in the first 500 to undergo 68 years of time, and and then fell to normal levels with laptop, as long as after 810 years.2004 Dawning 4000A total investment of nearly 100 million yuan, 10 trillion times and today the same computing power as long as one hundred to one hundred thousand yuan. And, even worse is that so large a system running at full capacity every day tariffs as high as 10,000 yuan.
