Virtual computation environment service (revised on 1 Oct 2015)

This service is an experimental service.
Please read carefully the terms of use before application.

Service overview

Multi-purpose virtual machines (VMs) are provided via network using computers managed and operated by ACCC. Two types of VM may be selected, depending on the purpose: intranet VMs accessible from only inside RIKEN, and global VMs. The VMs provided by this service are relatively small scale, but they are highly flexible with“superuser authority” given to users.


 Related services

  • For high-performance and large-scale calculations please use a supercomputer.
  • For data sharing, please use the file delivery (ふぁいる便) service as it is a more suitable service. For large-scale data management, please use data depository service with faster connectivity and larger capacity.  For more details, please refer to the ACCC website of each campus.
  • The RIKEN cloud service includes the CMS service (WordPress server) for dissemination of official information that specializes in information published on the web and allows users to edit and publish contents easily on their web browser.

The VM size may be selected from Tiny, Standard and Large machines.
The resource is limited to 144GB of memory and 8TB of data disks for each laboratory (PI).
( “Large machine” menu is closing temporary due to limit of residual resources. Other menu will close too when the resources full. )

100GB (fixed capacity) of OS disk is provided.  A back-up tool is supported.

2TB (fixed capacity) of data disk is provided as an option.  Any back-up tools are not supported..

The network connected to the VM may be selected from the intranet accessible from only inside RIKEN, or the global network.

The default OS is CentOS.  Other OSs may not be supported.

Note that the data on the optional data storage are removed at the same time the corresponding VM is removed.


OS disk backup

Backups of virtual machine images for the second generations of the previous two days may be downloaded. The downloaded VM images allow users to launch the VM on the RIKEN cloud infrastructure and/or on a user’s PC that satisfies certain specification.  Please refer to this page for the concrete management procedure of the data backup.


VM management

For users to launch or terminate their VMs, a web tool accessible via a web browser is provided. Please refer this page for details. ACCC does not manage VMs, including updating of OSs, applications, settings, etc.


Usage fees

The service may be used free of charge for the time being


Application

RIKEN employees with a RIKEN ID starting with a number is permitted to use this service. Download an application form for global or intranet.
A completed application form should be submitted in writing the ACCC office on any campus, or sent in writing to ACCC Wako office via internal mail.


Flow of the application procedure

The flow of the application procedure is written on the application form in detail. A security inspection procedure is necessary for the global network selected, and it takes several days to connect outside of RIKEN. Please give yourself plenty of days to apply.


 Terms of use

This service is provided as an experimental service for the time being. The terms of use described below applies, in addition to the terms of use for the RIKEN cloud experimental service.

  • This is an experimental service provided in advance to obtain technical knowledge before offering the official service in the future. Therefore, this service may be inferior in certain ways, including its contents and procedures.
  • The service may be used free of charge for the time being.
  • RIKEN employees with a RIKEN ID starting with a number are permitted to use this service
  • The resource is limited to 144GB of memory and 8TB of data disks for each laboratory (PI).
  • ACCC may ask the purpose of utilisation when a laboratory (PI) requests many virtual machines.
  • Use of the virtual machines offered by this service expires at the end of the fiscal year. If you would like to continue to use the virtual machines, a continuation application must be submitted, which will be announced at the end of the fiscal year.
  • When you finish the use of this service, please apply for the demolition using the application form listed above.
  • As a characteristic of the virtualization technology, the service quality including the processing performance, may drop or fluctuate due to competition of resources.
  • Though ACCC pays much attention to the distribution of computer resources so that this service can be provided to as many users as possible, an application may be declined due to the number of applications. Equitable screening is not guaranteed.
  • ACCC does not manage VMs, including updating of OSs, applications, settings, etc. These operations should be carried out by the users, in principle.
  • We may refuse to use if there is a use that impedes the provision of services.
  • Remodelling of the virtual computer itself such as OS replacement is forbidden.
  • Users with questions and requests are asked to contact ACCC (accc-support@riken.jp).
