Virginia Polytechnic Institute and State University, more often known as Virginia Tech, is using high-performance computing (HPC) in the Microsoft Azure cloud, together with parallel laptop computing, to support a cancer research programme. <\/p>\n
Wu Feng, a professor of computer science at Virginia Tech, said: We looked at trying to empower cancer biologists to tackle problems they would not be able to tackle by unleashing the power of parallel computing to the masses, enabling discoveries to be made faster. <\/p>\n
Feng said the computer industry is unable to keep up with the data processing requirements of DNA sequencing. \"DNA sequencing has accelerated faster than we can compute. The amount of data coming out of DNA sequencing doubles every six months, while computing power only doubles every 24 months.\" <\/p>\n
The university has used Microsoft Azure to enable Feng and the team of researchers to keep up with DNA sequencing data growth. <\/p>\n
When I first started this research, we doubled DNA data every 12 months, then it went to nine months, then to six, said Feng. <\/p>\n
From a computational perspective, quadrupling the technology is cost prohibitive, since the requirements of the DNA researchers outpace the economic model based on Moores Law, which the IT industry generally follows. <\/p>\n
While it is possible to buy twice as much for the same financial outlay every 18 months to two years, as stipulated by Moores Law, according to Feng the researchers needed four times as much IT every two years. <\/p>\n
We needed to look at innovative tools to avoid having to quadruple IT resources every six months, he said. <\/p>\n
An exhaustive search on the genome involves a medium-sized dataset, but Feng said processing involves big compute and big output data. He said next-generation DNA sequence analysis will involve big input data, big compute, and the application could output anything from small to very large datasets. <\/p>\n
The university tried building a proof-of-concept application using its supercomputer, called HokiSpeed a 400-processor system with 2,400 CPU cores and 400 GPU cards, where each GPU card used 400 cores. This machine made the supercomputer Top500 list a few years ago but, according to Feng, it timed out when the researchers tried to run the proof-of-concept DNA analytics application. <\/p>\n
