SANKT AUGUSTIN / JÜLICH, Germany, Dec. 16 -- Fraunhofer Institute for Algorithms and Scientific Computing (SCAI) and Jülich Supercomputing Centre (JSC) have used automated annotation software on grid-connected supercomputers to perform powerful queries in more than 50,000 pharmaceutical patents.
Researchers at the Fraunhofer Institute for Algorithms and Scientific Computing (SCAI) and at the Jülich Supercomputing Centre (JSC) of Forschungszentrum Jülich have used their substantial computing grid infrastructures for a new application in scientific computing: the large-scale annotation of biomedical and chemical texts and images in pharmaceutical patents. This will allow patent searches of an unparalleled power. Now, queries provide interesting insights into intersections between biology and chemistry, and the analysis of chemistry is truly multi-modal in the sense that text- and image-based information can be analyzed simultaneously.
More than 50,000 patents describing inventions in pharmaceutical chemistry have been processed on the large-scale computing grid infrastructures at SCAI and JSC. Automated "named entity recognition" services have identified and annotated:
The grid middleware UNICORE (Uniform Interface to Computing Resources) was used to manage the annotation services in the grid infrastructure, to control the streams of input and output data from the patents database to the annotation services, and to monitor the overall progress.
"This large-scale experiment opens new perspectives in scientific computing," says Prof. Dr. Martin Hofmann-Apitius, head of the Department of Bioinformatics at Fraunhofer SCAI. "This type of application goes way beyond the usual simulation applications that we are used to in the scientific computing community."
So far, text mining applications have only been run on bibliographic databases of life sciences and biomedical information such as MEDLINE. But the extension towards a multimodal analysis including annotation of text- and image-based information in full text documents on grid infrastructures has never been done before.
"We are pleased to see that our institute, which has a strong record in numerical simulation, has contributed to a new field of applications for supercomputers: what we call knowledge computing is likely to become a new discipline on its own," emphasizes Prof. Dr. Ulrich Trottenberg, Director of Fraunhofer SCAI.
"UNICORE made it possible to run this experiment at such a large scale in computing grid infrastructures at SCAI and JSC," says Dr. Achim Streit, head of Distributed Systems and Grid Computing at JSC. "The powerful workflow and data management capabilities of UNICORE allowed to annotate the patents in a seamless and automated way. A supercomputer connected by UNICORE to the infrastructure of the German Grid Initiative (D-Grid) was used to perform the knowledge extraction. This initial step of the experiment demonstrates what is possible today and shows the potential for more complex production runs in the future, using HPC systems connected in grid infrastructures."
"This is a very good example of how powerful supercomputers at JSC equipped with world-class grid technologies like UNICORE can generate synergies to enable new fields of research. I am proud that JSC is a member of the international UNICORE open source community and leads its development," explains Prof. Dr. Dr. Thomas Lippert, Director of JSC.
The team at SCAI, led by Dr. Marc Zimmermann for the image analysis annotators and by Dr. Juliane Fluck and Dr. Christoph Friedrich for the text analytics part, is currently working on the in-depth analysis of the meta-information generated in the course of this large-scale in silico-experiment. Their colleague on the side of JSC in Jülich, Mathilde Romberg, is happy that after weeks of intensive work the first "production runs" have been completed. However, the teams on both sides know that there are another 1.5 million patents waiting for them.

In quieter times, sounding the bell of funding big science with big systems tends to resonate further than when ears are already burning with sour economic and national security news. For exascale's future, however, the time could be ripe to instill some sense of urgency....
In a recent solicitation, the NSF laid out needs for furthering its scientific and engineering infrastructure with new tools to go beyond top performance, Having already delivered systems like Stampede and Blue Waters, they're turning an eye to solving data-intensive challenges. We spoke with the agency's Irene Qualters and Barry Schneider about..
Large-scale, worldwide scientific initiatives rely on some cloud-based system to both coordinate efforts and manage computational efforts at peak times that cannot be contained within the combined in-house HPC resources. Last week at Google I/O, Brookhaven National Lab’s Sergey Panitkin discussed the role of the Google Compute Engine in providing computational support to ATLAS, a detector of high-energy particles at the Large Hadron Collider (LHC).

The study of climate change is one of those scientific problems where it is almost essential to model the entire Earth to attain accurate results and make worthwhile predictions. In an attempt to make climate science more accessible to smaller research facilities, NASA introduced what they call ‘Climate in a Box,’ a system they note acts as a desktop supercomputer.

At some point in the not-too-distant future, building powerful, miniature computing systems will be considered a hobby for high schoolers, just as robotics or even Lego-building are today. That could be made possible through recent advancements made with the Raspberry Pi computers.

When it comes to cloud, long distances mean unacceptably high latencies. Researchers from the University of Bonn in Germany examined those latency issues of doing CFD modeling in the cloud by utilizing a common CFD and its utilization in HPC instance types including both CPU and GPU cores of Amazon EC2.
