Seminar on e-Science and High Performance Computing


About eHPC

eHPC is a one day seminar aiming to bring together a community of researchers, developers, practitioners, and user involved with e-Science and high performance computing technology from both academic institutions and industries to discuss and exchange ideas. The objectives of the workshop are to build collaborations for interdisciplinary research, and to increase the awareness on technological advancement in e-science and HPC fields. The event will offer technical paper presentations, invited talks, discussions, and technology demonstrations by the e-Science and HPC communities.

Areas of interest include but not limited to e-Science applications, infrastructure and services; cloud computing; data analytic; scientific computing applications and tools. eHPC2017 is organized in conjunction with JCSSE 2017.

About each session

Panel discussion: Integrating HPC, Cloud, Data Analytic and Scientific Computing

How is this?


"High Performance Computing", "Cloud Computing", "Scientific Computing" and "Data Analytics”:  these 4 terms were born in separate timeframe and yet they co-exist today.  How are they different or how are they alike? What will be the future of them? 


The seminar should touch on

        • historical background on each of them

        • their transformation, then and now

        • their characters and suitability

        • their ecosystems

        • their roles in the big picture, enterprises, society, social and economics impact

        • and their future


Invited Talks:


Energy Function for Grain Boundary in Body-Centered Cubic Metals

Mr. Rajchawit Sarochowikasit

King Mongkut’s University of Technology


This research presents a large-scale calculations of grain boundary energies in body-centered cubic (bcc) metals, Fe, Ta, Mo, and W, are calculated based on the atomistic simulation. We construct 408 distinct grain boundaries for 

each metal. The characteristics of a large set of grain boundaries are composed of 127 tilt, 24 twist,and 257 mixed boundaries. This indicates that the energies of these grain boundaries in the bcc metals are strongly correlated, although the microscopic configurations are not essentially the same. We conclude that the grain boundary energies in the bcc metals might have a universal characteristic, which is scaled to fit between coherent twin energy and cohesive energy.


Cloud caching

Dr. Thepparit Banditwattanawong,

Kasetsart University


Big data has been increasingly hosted in off-premise clouds, for example, high-definition multimedia, electronic documents, social media contents, opensource packages, and cloud-hosted web contents. This is because cloud enables not only fast and economical big data analytics but also highly-scalable and distributed sharing of the data. This is the evolution of data volume, data placement and data consumption behavior that altogether has led to several cloud-computing problems including the downstream bandwidth saturation, increase in external cloud  data-out charge imposed by public cloud providers, and delayed cloud service responsiveness.


To address these problems, we would present the consumer-initiated partial replication of cloud-hosted data to consumer locus. We refer to this solution as client-side cloud caching.

Reactive Molecular dynamics (ReMD) allowing dynamic many-body bond formation and breakage requires significantly more computation power compared to the conventional static bond method. Recently, we developed a shift/collapse (SC) algorithm, a novel MD computation algorithm that utilizes optimal communication scheme for          n-tuple interaction, which significantly improves computation performance of ReMD [1]. Nevertheless, the original SC algorithm is incompatible with force computation based on neighbor list, which is a commonly used method for reactive potentials such as embedded-atom method (EAM), bond-order potentials (BOD), and reactive force fields (ReaxFF).

In this work, we have presented a new neighbor list-based force computation scheme for SC algorithm (NBL-SC), which enable both fast computation based on the commonly used neighbor-list method and the optimal communication scheme of SC algorithm. Implementation of the new method has been verified and the simulation results have been validated using a force fields with 2- and 3-body bond-breakable interactions. Here, performance benchmark showed significant simulation performance improvement of NBL-SC over the original SC algorithm with 1.33 and 3.29 speedups on small and large granularities (24 and 24,000 atoms per compute core), respectively. Large-scale benchmark also indicated simulation performance of up to 267 ns/day for grain size of 24 atoms/core on 1,296 cores of Intel Xeon processors. This ongoing work highlighted an important step towards highly efficient parallel MD algorithm for reactive MD simulation.

Ecoinformatics are applications of informatics to the field of Ecology to understand, monitor and manage efficiently. We have been working in this area ranging from underwater to cloud forest ecosystems with various types of sensor and various type of networking architectures. A number of Ecoinformatics applications such as coral sensor network, sound scape, tourism portal, smart farming and cloud-based smart city portal, in the recent developments of Cloud and IoT, will be discussed.
