Chinese Lab Speeds Through Genome Processing With GPUs 408

Posted by timothy from the looking-for-the-reset-button dept.
Eric Smalley writes "The world's largest genome sequencing center once needed four days to analyze data describing a human genome. Now it needs just six hours. The trick is servers built with graphics chips — the sort of processors that were originally designed to draw images on your personal computer. They're called graphics processing units, or GPUs — a term coined by chip giant Nvidia. This fall, BGI — a mega lab headquartered in Shenzhen, China — switched to servers that use GPUs built by Nvidia, and this slashed its genome analysis time by more than an order of magnitude."

      If one reads to page 2 of tfa, they only claim the technique works well in this instance. They go on:

      Even for computer-intensive aspects of analysis pipelines, GPUs aren’t necessarily the answer. “Not everything will accelerate well on a GPU, but enough will that this is a technology that cannot be ignored,” says Gollery. “The system of the future will not be some one-size-fits-all type of box, but rather a heterogeneous mix of CPUs, GPUs and FPGAs depending on the applications and the needs of the researcher.”

      and

      GPUs have cranked up the speed of genome sequencing analysis, but in the complicated and fast-moving field of genomics that doesn’t necessarily count as a breakthrough. “The game changing stuff,” says Trunnell, “is still on the horizon for this field.”

      So yes, the article is a bit breathless, but if utilizing GPUs helps cure my potentially impending genetic disorder, I'm all for it.

      I used to work with Texas Instruments TMS34010/32020/34082 processors in the 1990's. These were surface mounted onto a VGA graphics board, along with a number of TMS34082 vector processors and a few megabytes of memory (Hercules Graphics Station Card as an example). They had this really neat feature where you could cross-compile, download and execute programs on these boards as "extensions". You could do anything from encryption/decryption, image-processing to drawing lines and rendering triangles.

    It's hardly news that GPUs can be used to speed up parallel tasks/computations, but even so this article is a useful reminder of two things; 1) there are still many important processes that can be sped up by using GPUs, and 2) this can be achieved pretty much anywhere in the world.

    • The only reminder should bethat processors designs for different types of math can do that math faster than processors designed for other types of math.

      I don't understand why companies don't realize that. Running graphics on a floating point processors is like using a train to go across an ocean. Sure you can do it doesn't mean that it is a good idea.

    • I wonder if the AMD use of more cores, whereas Nvidia uses faster cores, would change the time. I have no idea how genetic algorithms work. I do know simple hashes like bitcoins are best on AMD.
    • I always wondered why FPGA's aren't used for this kind of stuff, or if they already are. I would imagine they would even be faster because you can design a circuit specifically optimized for the problem. But now that I think about it, NVidia and AMD put considerable amounts of resources into making them super fast and cheap. I guess price/performance ratio would be pretty damn good on a GPU vs FPGA.

      • I always wondered why FPGA's aren't used for this kind of stuff, or if they already are. I would imagine they would even be faster because you can design a circuit specifically optimized for the problem.

        I think they are to some degree, but there is a major barrier to adopting them: they require specialized programming knowledge which you won't find in most genomics centers. GPUs are commodity technology and APIs like CUDA are easier to tackle (and more transferable to other fields) than FPGA programming.

        • Are any researchers really looking for skilled FPGA designers? It's a pretty dedicated skillset, but work on research would be more interesting than my current job. Also, it should be noted that the devices themselves (FPGAs), and the tools needed for the design flow (particularly synthesis tools) are expensive, and computationally intensive in and of themselves. Unfortunately we don't have the open source tools of the software world available to us.
      • The versatility of FPGAs comes at a steep price in die area, power consumption, and operating frequency. If your design goal is "We want to do this specific kind of math Real Fast.", and somebody already makes an ASIC that does that kind of math Real Fast, the ASIC is generally a lot more cost effective than using FPGAs.

    • According to Jackson Lab’s TeHennepe, the feat BGI and NVIDIA pulled off was porting key genome analysis tools to NVIDIA’s GPU architecture, a nontrivial accomplishment that the open source community and others have been working toward.

      Can anyone familiar with current efforts shed more light on this? Who is working on open source bioinformatics and how much work has been done?

    Excerpt:

    At BGI, he says, they are currently able to sequence 6 trillion base pairs per day and have a stored database totaling 20 PB.

    The data deluge problem stems from an imbalance between the DNA sequencing technology and computer technology. According to Dr. Wang, using second-generation sequencing machines, genomes can now be mapped 50,000 times faster than just a decade ago. The technology on track to increase approximately 10-fold every 18 months. That is 5 times the rate of Moore's Law, and therein lies the problem.

    Obviously it would be impractical to upgrade one's computational infrastructure at that rate, so BGI has turned to NVIDIA GPUs to accelerate the analytics end of the workflow. The architecture of the GPU is particularly suitable for DNA data crunching, thanks to its many simple cores and its high memory bandwidth.

        Although at least in my field the problem is that no one ever thought to set lower limits on the quality of what you can call a genome. So now we get "genomes" made up of 100,000 contigs (many only a couple of hundred base pairs long) and even counting all of those, the total sequence might account for only 70% of the total size of the genome. But it's still a "genome" paper, which is still an instant ticket to Nature Genetics (or Nature Biotechnology if the assembly is REALLY bad).

        BGI is certainly one of the biggest offenders (Cucumber and Pigeonpea are both examples of the sort of terrible genomes-in-name-only BGI puts out) but I think the real problem is that Illumina sequence data is so cheap people keep trying to use it to sequence genomes, thinking if they throw enough raw data and enough mate-pair libraries at the problem it'll eventually make up for the fact that Illumina reads are so short. Illumina data is great for a lot of things. Calling SNPs, measuring gene expression, studying methylation patterns.

        But, at least for any genome significant transposon content, it simply does not work.
        • Incidentally, ABI claims you can do de novo with SOLiD systems (which have read lengths of only ~20 bp!) but they say you need to get about 300x coverage just for a bacterial genome. That's not a lot of saved money when you work out all the numbers. It looks like we've nearly found a state function for dollars-per-high-quality-nucleotide.

          • you need to get about 300x coverage just for a bacterial genome

            OUCH. Wasn't the original high-quality human genome sequence (using Sanger technology) only about 10x? And doesn't having only 20bp per read basically rule out de novo sequencing of any eukaryote? Even for bacteria that sounds tricky without a closely-related reference sequence.

            • Yes, yes, and yes. To be fair, these are comparatively cheap and fast runs, but the numbers are still ridiculous, I agree. Hopefully third-generation sequencing technologies (not counting Pacific Bio's implausible promises of "3.1 billion flying pigs in 30 seconds flat!") will do better at pandering to us poor underfunded evolutionary biologists.

    • The problem with next generation sequencing is that it produces a lot of garbage as well. There is no free lunch. And that is why a lot is passed on computers to handle that garbage. Also, computation speed hours per genome annotation does not make sense without reference to what exactly and at what reliability is being annotated,

  • I get that programmers are offloading certain tasks to the GPU because they are able to perform specific tasks faster, but why is this even necessary. If the GPUs are so good at it then why can't there be a dedicated part of the CPU to perform these same computations in parallel streams the same way the GPU does?
