Service information
Service specifications
Service usage time
In principle, it is available 24 hours a day, 365 days a year.
However, we do not guarantee the occupancy rate.
If maintenance is to be performed that requires service suspension, we will notify you two weeks in advance of the work date.
Support hours
For inquiries regarding service operations, please contact us using the inquiry form.
We will respond between 10:00 and 17:00 on business days determined by our company.
For urgent inquiries, please contact us via our main telephone number (03-6665-0146).
Maintenance time
Due to reasons such as system maintenance and version upgrades, we will carry out maintenance work on a regular or temporary basis.
If we perform maintenance work that involves service suspension, we will notify you two weeks in advance of the work date.
Version upgrade
We will periodically or ad hocly update the version due to reasons such as addition of calculation functions, corrections, security enhancements, etc.
In the case of version upgrades that involve additions or corrections to functions, we will notify you of the version update information in the release notes.

Concept of calculation points
When performing calculations, you can select and use one of the calculation environments listed below. In each calculation environment, arithmetic units are started in "startup units".
HPC (Product Run) allows you to perform parallel calculations by starting multiple nodes at the same time.
1. Small scale test
Boot unit: 1 core*
Maximum parallelism per node*: 128
Consumption calculation points per startup unit: 10pt/core・hour
2. HPC Product Run
Startup unit: 1node*
Maximum parallelism per node*: 64
Consumption calculation points per startup unit: 1,280pt/core・hour
*“core” refers to the equivalent of a virtual CPU (vCPU) in Amazon Web Service.
*One unit of "node" is equivalent to 128 cores.
*The "parallel count" is the product of the process parallel count and the thread parallel count.
⚫The cost of calculation execution will be paid with pre-purchased points.
⚫The number of points required to perform the calculation is as stated above, and the number of points required for one job will be determined at the end of the calculation and will be deducted from the number of points held.
⚫The number of points required for one job is calculated including the time required to start and stop the computing environment.
⚫The number of parallels and calculation time are set when submitting a calculation job, and if the expected number of consumed points calculated from them exceeds the number of points held, the calculation job cannot be submitted.
