Live-Blog: Overview of High Performance Computing by Dr. Vipin Chaudhary

(This is a live-blog of Dr. Vipin Chaudhary talk on Trends in High Performance Computing, organized by the IEEE Pune sub-section. Since this is being typed while the talk is going on, it might not be as well organized, or as coherent as other PuneTech articles. Also, links will usually be missing.)

Myths about High Performance Computing:

  • Commonly associated with scientific computing
  • Only used for large problems
  • Expensive
  • Applicable to niche areas
  • Understood by only a few people
  • Lots of servers and storage
  • Difficult to use
  • Not scalable and reliable

This is not the reality. HPC is:

  • Backbone for national development
  • Will enable economic growth. Everything from toilets to potato chips are designed using HPC
  • Lots of supercomputing is throughput computing – i.e. used to solve lots of small problems
  • “Mainstream” businesses like Walmart, and entertainment companies like Dreamworks Studioes use HPC.
  • _(and a bunch of other reasons that I did not catch)

China is really catching up in the area of HPC. And Vipin correlates China’s GDP with the development of supercomputers in China. Point: technology is a driver for economic growth.  We need to also invest in this.

Problems solved using HPC:

  • Movie making (like avatar)
  • Real time data analysis
    • weather forecasting
    • oil spill impact analysis
    • forest fire tracking and monitoring
    • biological contamination prediction
  • Drug discover
    • reduce experimental costs through simulations
  • Terrain modeling for wind-farms
    • e.g. optimized site selection, maintenance scheduling
    • and other alternate energy sources
  • Geophysical imaging
    • oil industry
    • earthquake analysis
  • Designing airplanes (Virtual wind tunnel)

Trends in HPC.

The Manycore trend.

Putting many CPUs inside a single chip. Multi-core is when you have a few cores, manycore is when you have many, many cores. This has challenges. Programming manycore processors is very cumbersome. Debugging is much harder. e.g. if you need to get good performance out of these chips then you need to do parallel, assembly programming. Parallel programming is hard. Assembly programming is hard. Both together will kill you.

This will be one of the biggest challenges in computer science in the near future. A typical laptop might have 8 to 10 processses running concurrently. So there is automatic parallelism, as long as number of cores is less than 10. But as chips get 30, 40 cores or more, individual processes will need to be parallel. This will be very challenging.

Oceans of Data but the Pipes are Skinny

Data is growing fast. In sciences, humanities, commerce, medicine, entertainment. The amount of information being created in the world is huge. Emails, photos, audio, documents etc. Genomic data (bio-informatics) data is also huge.

Note: data is growing way, way faster than Moore’s law!

Storing things is not a problem – we have lots of disk space. Fetching and finding stuff is a pain.

Challenges in data-intensive systems:

  • Amount of data to be accessed by the application is huge
  • This requires huge amounts of disk, and very fat interconnects
  • And fast processors to process that data

Conventional supercomputing was CPU bound. Now, we are in the age of data-intensive supercomputing. Difference: old supercomputing had storage elsewhere (away from the processor farm). Now the disks have to be much closer.

Conventional supercomputing was batch processed. Now, we want everything in real-time. Need interactive access. To be able to run analytic and ad hoc queries. This is a new, and difficult challenge.

While Vipin was faculty in SUNY Buffalo, they started an initiative for data-intensive discovery initiative (Di2). Now, CRL is participating. Large, ever-changing data sets. Collecting and maintaining data is of course major problem, but primary focus of Di2 is to search in this data. e.g. security (find patterns in huge logs user actions). This requires a new, different architecture from traditional supercomputing, and the resulting Di2 system significantly outperforms the traditional system.

This also has applications in marketing analysis, financial services, web analytics, genetics, aerospace, and healthcare.

High Performance Cloud Services at CRL

Cloud computing makes sense. It is here to stay. But energy consumption of clouds is a problem.

Hence, CRL is focusing on a green cloud. What does that mean?

Data center optimization:

  • Power consumption optimization on hardware
  • Optimization of the power system itself
  • Optimized cooling subsystem
  • CFD modeling of the power consumption
  • Power dashboards

Workflow optimization (reduce computing resource consumption via efficiencies):

  • Cloud offerings
  • Virtualizations
  • Workload based power management
  • Temperature aware distribution
  • Compute cycle optimization

Green applications being run in CRL

  • Terrain modeling
  • Wind farm design and simulation
  • Geophysical imaging
  • Virtual wind tunnel

Summary of talk

  • Manycore processors are here to stay
    • Programmability have to improve
    • Must match application requirements to processor architecture (one size does not fit all)
  • Computation has to move to where the data is, and not vice versa
  • Data scale is the biggest issue
    • must co-locate data with computing
  • Cloud computing will continue to grow rapidly
    • Bandwidth is an issue
    • Security is an issue
    • These issues need to be solved

Dr. Vipin Chaudhary, CEO of CRL
Dr. Vipin Chaudhary, CEO of CRL, will give a talk on High Performance Computing at Institute of Engineers, Pune. CRL are the makers of Eka, one of the world's fastest privately funded supercomputers. For more information about HPC and CRL, click on the photo above.

Computation Research Laboratories (CRL) is the Pune-based company from the Tatas which built the Eka supercomputer. Eka was the 4th fastest when it launched a few years back, but has now dropped to 33rd; nevertheless, it remains one of the fastest private (i.e. not funded by any government) supercomputers in the world.

Earlier this year, Dr. Vipin Chaudhary took over as the CEO of CRL. I assume this marks a change in direction for CRL. Earlier, the focus was on building Eka, which required lots of cutting edge research in hardware, software, and facilities among other things. During that phase it was developed and run by academics (CRL was started with the help of Dr. Narendra Karmarkar, and most of the senior executives in CRL were ex-IIT-Bombay professors. Now, however, it is likely that they’re looking for a return on the investment, and would like to start marketing high performance computing services using Eka. They have a team working on high performance infrastructure and applications using the Eka hardware, and being a purely private company, are in a unique position to offer their hardware, software and services to companies who might be interested in supercomputing applications (think airplane design and modeling (e.g. somebody like Boeing), or car design (e.g. for in-house use like Tata Motors)). Dr. Chaudhary, who relocated from the US for this role, has been earlier involved with two startups (Corio, acquired by IBM in 2005) and Cradle Technologies (2000-2003), in addition to being an associate professor at SUNY Buffalo. Thus the credentials he brings, specifically his strong technical and business background in this area, are impressive.

CRL, is working on some of the most complex technologies in Pune. For that reason alone, any techie in Pune should be interested in this talk.

Yahoo and CRL (EKA) to collaborate on cloud computing research

(Link courtesy Amit Paranjape via e-mail)

Yahoo and CRL have just announced that they will collaborate on research into cloud computing. I believe this announcement is essentially about Yahoo’s use of Hadoop on CRL’s EKA supercomputer.

This Yahoo!/CRL announcement comes on the eve of the first ever Hadoop Summit. Apache Hadoop is a Free Java software framework that supports data intensive distributed applications running on large clusters of commodity computers. It enables applications to easily scale out to thousands of nodes and petabytes of data. In Feb 2008, Yahoo announced that its Search Webmap application has been converted to a Hadoop application that runs on a more than 10,000 core Linux cluster and produces data that is now used in every Yahoo! Web search query.

CRL’s EKA supercomputer is a Hewlett-Packard based system with 14,400 processors, 28 terabytes of memory, 140 terabytes of disks, a peak performance of 180 trillion calculations per second (180 teraflops), and sustained computation capacity of 120 teraflops for the LINPACK benchmark. Of the top ten supercomputers in the world, EKA is the only supercomputer funded by the private sector that is available for use on commercial terms.

This announcement should also increase the interest in attending the presentation on EKA to be held here (i.e. in Pune) in a few days (Thursday, 27th March). The talk promises to be very interesting, especially given the background of speakers Dr. Lagu and Dr. Sherlekar (who used to be profs in IIT-B amongst other things). Details.

Upcoming Event: Seminar on CRL’s Supercomputer (4th fastest in the world)

A presentation on CRL’s EKA supercomputer will be held next Thursday evening. Considering that it is one of the fastest supercomputer in the world, and considering the qualifications of the speakers (see below), it promises to be an interesting talk.


When: 27th March 2008, 6.30 to 8 pm.
Where: MCCIA, Crossword Building 5th Floor, Hall 4 & 5, Senapati Bapat Road
Price: No entry fee.

CRL’s EKA Supercomputer – Architecture and Applications

Computational Research Laboratories (CRL) has recently designed and built a high performance computer (HPC) system called EKA (Sanskrit word for “one”) which has been rated fourth fastest in the world and fastest in Asia. This rating was announced in the recent Supercomputing 2007 conference held in Reno, Nevada in USA. Of the top ten supercomputers in the world, this is the only computer funded by private sector and is available for usage on commercial terms. CRL is a fully owned subsidiary of Tata Sons Limited. The Tata group has always contributed to scientific research in India and EKA will strengthen this cause with appropriate public-private partnerships.

The senior team from CRL will cover salient aspects of EKA — architecture and applications.
