3. Call for Startup Preparation Projects for Japan’s Fugaku Supercomputer*
Available resource: RIKEN R-CCS Supercomputer Fugaku

Application Period**: 

  • Now – 28 February 2021, 2359 hrs+
    (for consultation with NSCC before submission to Japan’s HPCI)
  • Now – 31 March 2021, 2359 hrs 
    (for direct application to Japan’s HPCI)

Project Period: Up to six months until the end of March 2021

*The purpose of the call is to help future Fugaku projects smoothly start up and create results, and to accelerate software verification, tuning, and other related operations. Additionally, user feedback will be used to improve the Fugaku environment.
**May be closed earlier at the discretion of HPCI and once all the available resources are allocated
+NSCC is offering to work together with Singapore researchers and to assist in jointly reviewing proposed submissions
Working with NSCC for your submissions
Through a partnership between R-CCS, Research Organization for Information Science and Technology (RIST) and National Supercomputing Centre (NSCC) Singapore, the Fugaku system is now open to Singapore researchers interested to leverage the HPC resources of the world’s premier supercomputer.
NSCC, in collaboration with our partners from Japan, is helping to coordinate a whole-of Singapore call for HPC startup projects to tap on to the incredible supercomputing power of Fugaku. NSCC is also offering to work with advanced, high-end Singapore HPC research projects to assist them in jointly reviewing proposals for resources to perform their ground-breaking HPC research using the Fugaku system.
Alternatively, interested projects are free to submit their proposals directly to Japan via HPCI.

For more information, go to

Who should apply?
As a guide, let us know if your research falls under one of the following categories:
  • Singapore research projects in all relevant fields (eg. genetics, advanced modelling & simulation, biomedicine, materials development, etc.) with requirements for advanced high performance computing (HPC) resources
  • Singapore research projects which are at the forefront of HPC and with the potential for national and global high-impact outcomes (eg. requiring vast amounts of HPC resources, potential for high-impact outcomes or deliverables, etc.)
How do I apply?
If you are interested to apply for Fugaku’s HPC resources, here’s what you need to do:
  • Please refer to the Application Procedure for more details
  • Your application will be processed locally and NSCC will work with you in putting up a project proposal to RIST, the organisation administering the project calls to Fugaku
  • NSCC will be working with R-CCS and RIST to facilitate the project proposals and the access to Fugaku
For clarification and queries, please contact NSCC at [email protected].
About the R-CCS, RIST and NSCC partnership
1.       Overview
partnership between Singapore’s national supercomputing resource, NSCC, Japan’s RIKEN and RIST allows Singapore-based researchers to directly access the vast supercomputing resources of the world’s fastest supercomputer, Fugaku. At 442 Petaflops (PFLOPS) of computing power, Fugaku is nearly three times more powerful than its nearest competitor and is at the top of the latest November 2020 edition of the global TOP500 supercomputer listing.
Singapore researchers will now be able to apply for Fugaku’s huge computing resources through regular project calls and connect directly via dedicated high-speed, high-bandwidth research optical fibre links of up to 100 Gbps. The accessibility to Fugaku’s computing resources is in addition to Singapore’s petascale compute power that local researchers already have available at NSCC.
“Singapore researchers will have the honour of being one of the first in Asia to have access to the amazing compute power of Fugaku.”
– Associate Professor Tan Tin Wee, Chief Executive of NSCC
“We hope that by sharing such examples and Fugaku’s resources we can inspire more of our researchers, and colleagues from other countries, to leverage the power of HPC in their own research work. This partnership between the top tier national HPC centres of Japan and Singapore is a significant step in that direction.”
 –       Professor Satoshi Matsuoka, Director of R-CCS
2.          Eligibility & Requirement
       a.  Open to all researchers from Singapore institutions for the use of the Supercomputer Fugaku 
            and/or the Fugaku testbed at R-CCS 
       b.  Up to 100,000 node-hours of compute resources available for competitive allocation
       c.  Projects intending to prepare for formal application to use Fugaku from March 2021(e.g. software
            verification, porting, tuning, test runs before production runs)
3.      Application Procedures
Interested applicants may follow the steps below to submit an application:
     a. Download the Application Form
     b. Fill up and complete the form while referring to A Guide for Proposal Writing
     c. Submit the form to [email protected] with the email title “Application: Call for Fugaku
         Startup Projects^
     d. After NSCC receives the application, we will be contacting you for a follow up and a review process
         with experts from Singapore and Japan to help guide you to a successful application^
     e. The final version of the form can then be submitted through the HPCI Online Application System
     f. You may refer to the HPCI Quick Start Guide for the creation of an HPCI-ID
     g. R-CCS will assess, review and approve the applications for the usage of Fugaku, including assessing
        whether an application is compliant to the export controls regulations of the jurisdiction to which
        R-CCS belongs.
^Note: Alternatively, you may wish to submit your application to HPCI independently. If so, you may omit steps ‘c’ and ‘d’ in your application process if you wish, but please indicate in your direct application that you are part of this collaborative arrangement between NSCC-RIKEN-RIST.
