  1. [Research description]

Please describe in a comprehensible way. You can attach reference figures such as graphs or illustrations.

1.1.Scientific background, research purpose, scientific characteristics (10--20 lines)

If this research thesis is related to research conducted at a laboratory or by a research group or is a part of them, describe their relation specifically

1.2.Research plan, computation methodsand expected achievements

Describe the actual roll of each member.

If your primary employer is not RIKEN(e.g. visiting scientist),describe the actual role you will play in the collaborative research.

If you have conducted a related research using supercomputer systems (in RIKEN or others), provide current research situation and future schedule

1.3.Justification to use HOKUSAI in an Exclusive Use, if you apply for the Exclusive Use Category

  1. [Necessary CPU resources]

2.1.Period of time you will need to estimate

months (estimation must finish by the end of the fiscal year)

2.2.Necessary computation time

Describe necessary “core hours” for each resource.

See “SYSTEM OVERVIEW” () for the details of the system. Note that RICC will be removed at the end of December 2016.

If the computation time is permitted, this is not guaranteed but maximal value.

The allocatable computing resources and allocatable ratio of core-hours for additional projects in the 2nf half of FY2016 are as follows:
Massively Parallel Supercomputer (GW-MPC)
24,219,648 core-hours (8 % of total core-hours in the FY)
Application Computing Servers (GW-ACSL)
378,432 core-hours (36 % of total core-hours in the FY)
Application Computing Servers (GW-ACSG)
1,892,160 core-hours (30 % of total core-hours in the FY)
Embarrassingly parallel jobs and data analysis system(RICC)(until the end of December 2016)
8,091,600 core-hours (25 % of total computing resources in the FY)
-Users should apply for General Use to use 1% or more of the computational resources in the period of time you use (e.g. the half of above for 6 months). The application is required for use of 1% of any one of the computing resources.
-Each user and project cannot apply more than 20% of the computational timeof each resources (GW-MPC, GW-ACSL, GW-ACSG, RICC).
-Approved users for General Use for one resource are permitted to use other computational resources as Quick Use users
-It costs US$ 6.6M for the operation of the supercomputer system in a year.

Massively Parallel Supercomputer (GW-MPC)

Total Computation Time core hours

Application Computing Servers (GW-ACSL)

Total Computation Time core hours

Application Computing Servers (GW-ACSG)

Total Computation Time core hours

Embarrassingly parallel jobs and data analysis system (RICC)

Total Computation Time core hours

Calculation method:
Computation time is a total of [number of cores x elapsed time] for all jobs. For example, if you wish to run 500 jobs on 1024 cores for 24 hours, your computation time will be 1024 x 24 x 500 = 12,288,000 core x hours.
If you run multiple jobs using the different numbers of cores, write a total number

2.3.Justification for the computation time you requested in the item 2.2.

Please describe using the values measured in the Quick use project or last FY project.

Please describe the demand of the number of jobs in the usage period and computation time you mention in 2.1, 2.2.

Please describe the necessary computing resources (core hours) of each member. Core hours should be described for each resource (GW-MPC, GW-ACSL, GW-ACSG and RICC).

Justification for computation time is treated as important by the Review Committee. Please provide adequate explanation.

Example: My fluid computation on 1024 cores took 24 hours to complete. Since I wish to run this job with 500 different parameters, I will need 12,288,000 core x hours as I requested above.
