The whitefly is having a devastating effect across East Africa by spreading viruses to the cassava plant, a staple food in the region. An infestation can decimate an entire harvest, leading to economic hardship and famine.
While they look identical, there are actually many species of whitefly. In order to develop resistant crops, they must be distinguished and the best way to do this is to examine their genetic differences.
Professor Laura Boykin and her colleagues at the University of Western Australia have been collecting whiteflies, extracting the insect DNA, and using sequencing machines to generate their genome.
To make sense of the billions of genetic base pairs, researchers have to apply sophisticated algorithms, to genetically distinguish the flies. That process takes significant computational resource. It takes a supercomputer like Magnus.
Magnus is Pawsey Supercomputing Centre in Perth's flagship machine, and one of the most powerful supercomputers in Australia. The most powerful is Raijin, operated by National Computational Infrastructure (NCI) at the Australian National University.
But Australia's two Tier 1 high performance computing (HPC) research facilities are in "urgent" need of a refresh. Their supercomputers are fast approaching end-of-life, just as demand from academics needing the compute power to crunch massive datasets is rising.
It's not hyberbolic - given research such as Boykins' - to say there are lives at stake.
"HPC and genomics is the future," Boykin told Computerworld. "Building capacity at the integration of these two disciples is key to solving huge problems - like famine in East Africa."
There comes a point in every supercomputer's lifecycle when they are not so super anymore.
When it became fully operational in 2014, Pawsey's petascale system Magnus was the 41st most powerful computer in the world.
By 2015 it had slipped to 58 on the LINPACK Benchmark Top500 ranking. The latest list, released last month, placed Magnus at 111.
"The problem is compute technology - in many ways it accelerates faster than you'd like it to!" says David Schibeci, head of supercomputing at Pawsey. "At a certain point, we understand that all supercomputers have an end of life."
The support contract for Magnus - which is currently running at near capacity - lapses in September. Pawsey has received a government funding boost to cover its next two years of operations.
"Part of that money will be to extend that support contract so we can still look after Magnus," Schibeci explains.
The NCI's Raijin supercomputer currently comes in at number 70 in the world ranking, with a performance of 1.67 Petaflops - comparable to about 40,000 desktop computers working simultaneously. When it debuted in 2012, Raijin was placed at 24.
