The memory-intensive node service ended at 15:00 on October 27, 2023.
Among them, interactive nodes, and compute nodes(V) are equipped with 2 ports of InfiniBand EDR, compute nodes(A) are equipped with 4 ports of InfiniBand HDR and they are connected by InfiniBand switch group together with Storage Systems described later.
Below are the details of these nodes.
Interactive Node
The ABCI system provides two types of compute nodes: compute node (V) and compute node (A). To improve the convenience of program development for each compute node, we provide two types of interactive nodes: interactive node (V) and interactive node (A).
When developing a program for each compute node application, use the corresponding interactive node. It is possible to submit jobs to both compute nodes from either interactive node.
The interactive node of ABCI system consists of FUJITSU Server PRIMERGY RX2540 M4. The interactive node is equipped with two Intel Xeon Gold 6148 Processors and 384 GiB of main memory available.
The specifications of the interactive node are shown below:
| Item | Description | # |
|---|---|---|
| CPU | Intel Xeon Gold 6148 Processor 2.4 GHz, 20 Cores (40 Threads) | 2 |
| Memory | 32 GiB DDR4 2666 MHz RDIMM (ECC) | 12 |
| SSD | SAS-SSD 3.2 TB | 4 |
| Interconnect | InfiniBand EDR (100 Gbps) | 2 |
| 10GBASE-SR | 2 |
Users can login to the interactive node, the frontend of the ABCI system, using SSH tunneling via the access server.
The interactive node allows users to interactively execute commands, and create and edit programs, submit jobs, and display job statuses. The interactive node does not have a GPU, but users can use it to develop programs for compute nodes.
Please refer to Getting Started ABCI for details of login method and Job Execution for details of job submission method.
Warning
Do not run high-load tasks on the interactive node, because resources such as CPU and memory of the interactive node are shared by many users. If you want to perform high-load pre-processing and post-processing, please the compute nodes. Please note that if you run a high-load task on the interactive node, the system will forcibly terminate it.
Compute Node
The compute node in an ABCI system consists of a compute node (V) and a compute node (A). To execute the program for the compute node, submit the program to the job management system as a batch job or an interactive job. Interactive jobs allow you to compile and debug programs, and run interactive applications, visualization software and so on. For details, refer to Job Execution.
Compute Node (V)
The compute node (V) of ABCI system consists of FUJITSU Server PRIMERGY CX2570 M4. The compute node (V) is equipped with two Intel Xeon Gold 6148 Processors and four NVIDIA V100 GPU accelerators.
