What's New at GSICThe Global Scientific Information and Computing Center(GSIC) was established in April 2001 by amalgamating
Tokyo Institute of Technology's Computer Center and theInternational Cooperation Center for Science andTechnology.
GSIC's missions are to apply advanced information
technology to support research and education activities andto use the technology as a medium for promoting researchcollaboration at an international level. In line with thesemissions, GSIC has been showing steady results indeveloping the university's information infrastructure andsupporting its operation, in supporting cutting-edge researchin high-performance computation and further researchbased on its findings, as well as in using IT to promoteinternational collaboration.

History of GSIC
1971 Foundation of TITech Computer Center

GSIC Organization
In recognition of GSIC's achievements, it was designated a
Joint Usage / Research Center alongside the seven othersimilar centers nationwide. Starting April 2010, the GSIC
commenced activities as one of the constituent centers ofJapan High Performance Computing and Networking plus
Large-Scale Data Analyzing and Information Systems.
In July 2010, GSIC was restructured into an organization
with two divisions to help it play an even more effective rolein promoting cutting-edge research and international
research collaboration as a Joint Usage / Research Center.
After establishing the TokyoTech CERT to manage
information security of Tokyo Tech, some members of GSIC
have cooperated as the managers since April 2014. In
addition, TSUBAME 3.0 has been operating since August
2017, and it ranked No. 1 in the world on the Green500 listof energy-saving supercomputers.
GSIC hopes to continue living up to expectations of boththe university and the global community in the coming years
through its efforts relating to the university's information
infrastructure and advanced research activities.

Joint Usage/Research Center for Interdisciplinary
Large-Scale Information Infrastructures (JHPCN)

JHPCN is a network-type joint usage/research center and ismade up of eight supercomputer centers in Japan. Designed asa six-year program of MEXT, JHPCN’s first and second stages
began in FY2010 and FY2016, respectively.
The formal title of this program is "Joint Usage/ ResearchCenter for Interdisciplinary Large-scale Information Infrastructures", but it is also known as "Japan High Performance Computing and Networking plus Large-scale Data Analyzing andInformation Systems (JHPCN)".
The objective of JHPCN is to promote the continuous progressof academic research and to lay the groundwork for interdisciplin-ary collaborative research in Japan. JHPCN strives to tackle
highly challenging problems, which were previously thought
extremely difficult to solve, by using the combination of the eightcenters’ supercomputer resources and forming a collaboration
among their researchers. In the second stage of JHPCN, we also
encourage the international collaboration research, the industrial
research, and the challenging exploratory research.
GSIC promotes research collaborations on four research topics:
GPU computing and large-scale HPC applications, design andmanagement of new-generation supercomputers, big data anddata science, and artificial intelligence (AI), and deep learning.

High-Performance Computing Infrastructure (HPCI)

Campus Network Titanet3

HPCI links the Fugaku supercomputer and the supercomputers located in universities and research institutions
nationwide via high speed networks; it is a core system
contributing to the realization of a revolutionary high-performance computing environment to meet the needs of awide variety of users.

The campus network of Tokyo Tech has reached to Titanet3 after
the second upgrade in 2010. Titanet3 is a simple two-tier architecture that consists of 10Gbps core switches with high port density
and an edge switch located in each building, which are directly
connected by single-mode optical fibers. The upgrade not only
provides a high-speed, wide-bandwidth network but it also solves
the issues in the conventional 3-tier architecture, such as thebreakdown or power failure of the aggregation switches that canwidely affect the network, which improves the stability andoperability.
The core switches are setup in the same manner at both of the
Ookayama and Suzukakedai campuses, and the bandwidths ofthe connections between core switches are guaranteed by over
20Gbps. Specifically, the connection between core and edge
switches consists of two of the same 10Gbps links and each edge
switch provides 1Gbps bandwidth per staff member in eachbuilding. At the Tamachi campus, we also introduced WDM
facilities and constructed the same network environment as that ofother campuses.
For faraway research institutions such as the Kusatsu Volcanic
Fluid Research Center, we introduced FLET'S service to provide
access to the Titanet3 internal.
Furthermore, in addition to legacy services such as IPv6 andmulticast, several new features such as sampling-based traffic

The use of HPCI is expected to allow a wide array of
HPC users throughout the country to use it more efficiently and that this will accelerate the wider use of HPC from
germinating research to large-scale research projects.
GSIC provides a computer resource of TSUBAME3.0 for
both academic and industrial users.

analysis and virtual chassis technology have been introduced forhigh functionality and reliability.
For the connections to the Internet and outside research
institutes, Titanet3 is directly connected to academic research
network and projects such as SINET, APAN, WIDE and JGN, etc.,
and it is also designed to select the optimal route for communications. In 2016, with the upgrade of SINET, the network environment of the most frontier research projects has also been
upgraded. Specifically, the connection with SINET was increased
to 100 Gbps, and the total bandwidth for off-campus connections
110 Gbps.
In modern society, information communication is essential forhuman activities. Titanet3, one of the most important infrastructuresof Tokyo Tech, not only supports cutting-edge research, educational, and operational activities, but it also provides indispensable
services for daily campus life. Additionally, many systems havebeen designed to support university operations which include
campus authentication and authorization systems, campus wirelessnetworks, remote lecture systems, video conference systems,
internal telephone lines between campuses, power and water
meter-reading systems and a disaster Information broadcasting
system, among others. All of the above systems require campus
network services in order to operate. Therefore Titanet3 plays amajor role as the “foundation” for the infrastructure of the university.

guests, access to commercial wireless network services for
personal guests of the staff, and we introduced a worldwide
educational roaming service -“eduroam”.
At the time of Great East Japan Earthquake, we also provided afree wireless network temporarily to those affected, based on thepolicies of the provider.
As of March 2020, the total number of access points on campus
is 955, including the increased access points in new spaces andthose introduced in branches. Compared to other educational
institutions, this is an extremely large-scale wireless network, andthe number of both internal and external users continues toincrease.

The wireless network of Tokyo Tech campuses started in 2005,
primarily in lecture halls and popular spaces regularly used by
students, to provide network services to all laboratories. When
we firstly upgraded the wireless network in 2010, it reached toTitanet wireless 2 (TW2), which could accommodate a wide
variety of terminal devices with high capacity and reliability andwas compatible with high-speed communication standards.
With TW2, in addition to upgrading hardware devices, we also
updated the service policies such as allowing simple authentication, and constructed redundant controllers, and we also
obtained licenses to increase areas of access. Next, in addition
to conventional wireless network service for internal users, we
also added tentative wireless network services for conference

Tokyo Tech Mail

Tokyo Tech CERT (Computer Emergency Response Team)The "Tokyo Tech Mail" system began operating in 2006 inorder to provide a campus-wide email environment to Tokyo
Tech members i.e. students, academic and administrative
staffs.Since then, GSIC has been providing a reliable email
service, which enables a smooth exchange of information forvarious activities at the University, such as academics,
education, research, administrative management, and etc..
In 2012 and 2017, the system had major updates for further

improvement in convenience, quality of service use, andstability. They included the expansion of email spool size tocope with increasing in numbers of emails and amounts ofemail data, and a higher performance email filter to prevent
unsolicited (junk) emails.
Also, it became possible to access to the server securely from
off-campus network, when user communications related tosending and receiving emails were entirely encrypted by SSL.

Campus Software Agreement
Service outline

Tokyo Tech provides softwares that are widely used throughout the University, such as Microsoft Windows (OS), Microsoft
Office, security (anti-virus) software, Adobe Creative Cloud,and MATLAB under the campus-wide license agreements. It
greatly contributes not only to a reduction in software purchasecosts in laboratories (and hence reduction in overall university
expenses), but also to preventing the use of illegal software.

Furthermore, students and staffs can also use Microsoft
Office and security software on their personally owned PCs,
hence contributing to a better study and research environment.
In order to ensure the strict and proper license management,
we require the user authentication on the campus-wide
authentication and authorization system before providing thesoftware.

With the importance of information security growing, Tokyo Tech
CERT (Computer Emergency Response Team) was established
as a dedicated information security team in October 2014. It is
the role of Tokyo Tech CERT to provide a secure computer
environment to accelerate research / education / administrative
activities. In addition to security incident response, we conduct awide range of information security activities, such as sharing
security trends / alerts and examining campus vulnerabilities with
an emphasis on proactive response.
Our objectives include providing information and alerting
through the website (http://cert.titech.ac.jp) and using e-mails,
flyers and digital signage for Tokyo Tech members. In addition,
information security materials are available in Japanese andEnglish (and some in Chinese) in the form of booklets andvideos. These security booklets are distributed at various
information security seminars. Their content is also provided
electronically. For Tokyo Tech members seeking this content,
please do not hesitate to contact Tokyo Tech CERT.
Constructing a secure computing environment requires
cooperation not only with Tokyo Tech CERT, but also with variousorganizations and users. We collaborate with staff members of“authentication and networking group” who are in charge of
network infrastructure and authentication infrastructure throughdaily work and regular meetings, as well as members of information security risk management committees and the executive
office. We also collaborate with each organization in various
situations, such as the revision of university rules, the specifica-

tions for the introduction of large ICT systems, and the management of data in joint research.
While working on the above security announcement and theuniversity-wide cooperation, we are also working on various
technical aspects. As a major initiative, we operate several
next-generation security appliances in cooperation with the
Network Operation Center (NOC). In addition, in order to fully
utilize the detection function of those appliances, we are buildinga large-scale analysis platform on its own virtualization infrastructure environment. This analysis platform can handle a large
amount and various types of logs generated from those security
appliances. We are working to improve the quality of incident
response by utilizing these security devices and log analysis
infrastructure.
Computers and networks improve and innovate all modern jobs.
On the other hand, large amount of diverse data and computerresources are very attractive to cyber-attackers. Now, ensuring
information security is one of the essential items in all jobs. We
have to establish a communication system and a data management system. However, if used properly, these essential
measures can lead to the opportunity to review and make
improvements on the organization and its communication andteamwork. Tokyo Tech CERT is working to ensure that information security does not stagnate the activities of the organization,that various activities can be carried out actively because of the
secure environment, and that each organization can work
together to improve more than just ensuring information security.

Service outline

The IT Service Desk provides the information desk service byreceiving inquiries on telephone and email regarding the content
of all the services provided by the Global Scientific Information
and Computing Center (GSIC). When inquiries are not about
services provided by GSIC, they are transferred to thecorresponding sections/departments, so that a one-stop like
service is provided. According to the annual survey, the experiences of users have been favorable.
