13. Web application function

This chapter describes the operation when using the Web application.

13.1. Web service use function entrance

As a service entrance, "Use Web Service" is displayed in the menu on the left side and in the usage options on the group details screen.

"Web service usage" is displayed in the user information field of the menu displayed on the left side of the screen.

Click this link to move to the web service use reception screen.

13.1.2. Group detail screen

Web service usage is added to the usage options on the group details screen.
Click the setting button to move to the Web service use reception screen.

13.2. Web service use reception screen configuration

This section describes the Web service usage reception screen configuration.

The Web usage reception screen consists of two parts: a usage registration interface and a list of registered jobs.

No. name Explanation
1. Usage registration interface We accept the use of Web services. You can set the resource type and execution time when using
2. List of registered jobs A list of registered jobs is displayed. You can check the status of each job and perform operations such as canceling.

13.3. Web service reception interface

This section describes the Web service use reception interface.

No. name Explanation
1. Web application A drop-down list for selecting available applications.
2. Queue for interactive use only Use web services with a queue for interactive use only. The default usage time is 2 hours, but the settings can be changed.
3. Use of paid services Select when executing a Web application that uses a group point. You can select from two types: "usual node use (shared)" and "reserved node use (occupied)".
#If you use a reserved node, you will not be charged points for executing this application.
4. Trial use Web application execution using the "trial usage frame" of the tsubame-users group. The usage time is 10 minutes (fixed).
5. Node reservation fails Specify the action to be taken when the Web application execution node request fails.
6. Start-up The Web service will start to be used under the entered conditions.

13.3.1. About resource types

Select computer resources. The selectable resource items differ depending on the normal node usage and reserved node usage.
The available resource types are shown in the table below.

Resource type:Complex name f_node[F] h_node[H] q_node[Q] s_gpu[G] s_core[C1] q_core[C4]
Physical CPU cores 28 14 7 2 1 4
Memory size 240GB 120GB 60GB 30GB 7.5GB 30GB
GPU 4 2 1 1 0 0
SSD 1800G BbeeOND 900GB 450GB 224GB 120GB 225GB
Available on node reservation × × ×

13.3.2. Execution time

Enter the character string "hour: minute: second". When only "hour: minute" is entered, "hour: minute: 00" is complemented.

13.3.3. AR ID

Enter the ARID of the reserved node that executes this Web application.
This is a required input when using the reserved node.
It is necessary to make a node reservation from the portal and obtain the ARID in advance.

13.3.4. 4 Acceptance dialog

The content displayed in the dialog when the start button is pressed changes as follows depending on the input content.
Except for the place where the input value is described, the system will automatically judge and display it.

Resources used Reserved node ID Resource Type Utilization time Number of payment points
Interactive queue Interactive queue -- -- Input value --
Paid(Normal node) share -- Input value Input value Deposit points
paid(reserve node) Occupation Input value Input value Input value 0
Trial use share -- Input value 00:10:00 --

Display example

  • Interactive queue

  • Fee-based service use and normal nodes

  • Fee-based service use and reserved nodes

  • Trial use

13.4. Use web service

When a job is started by the web service execution function, an email with a URL to use the web application is sent to the email address registered in the portal.
The URL in the email can be used only once.

In addition, by clicking the [View] button on the Job List screen below, you can display the Web application in a separate window. If you want to display the web application again after using the URL in the email, use this option.

13.5. Web service job operations

This section describes the list of registered jobs.

No. name Function
1. Update button Update the contents of the registered job list.
2. Page selection menu (top) Switches the page of the registered job list.
3. List of registered jobs A list of registered jobs is displayed. The background color and button display vary depending on the status.
Item Content
State The preparation status after registration is displayed.
Operation Displays the available operation buttons according to the contents of the status column.
Group name Displays the group name where the job was executed. The group name is hidden during the trial period (group name: tsubame-users).
ARID Displays the AR ID at the time of reservation execution.
JOBID Displays the job ID.
CPU (core) Displays the number of physical CPU cores according to the resource type.
GPU Displays the number of GPUs according to the resource type.
TIME (h) Displays the job execution time.
Registration Displays the date and time when the job was registered.
Start Displays the date and time when the job started. If the job has not started, leave it blank.
End Estimated end time is displayed in gray after the job starts, and when it is completed, the last end time is displayed.
POINT Displays the points used. "-" Is displayed for non-paid use. While the job is being executed, it is displayed with () to indicate that it is a temporary holding point.

The operation column changes as follows, depending on the state of the job.

Status Operation Contents
Preparing Cancel Preparing for execution. Cancel the job before execution.
Running Display Open and transfer the operation screen of the Web service in a new window.
End Cancel the running job.
Stopping - The job is stopping.
End - It is a finished job.
Error - Job ended in error.
If you move the mouse cursor over the "Error" string, more information will be displayed as a tooltip.
We may ask you to confirm this information when you make an inquiry.

13.5.1. Canceling or terminating job

The job is automatically terminated by performing the termination operation in the web application.

If you want to cancel a job in "Preparing" after registration, or if you want to terminate a job in "Running" without going through the web application, you can select "Cancel" or "Exit" in the operation column, the following dialog will be displayed.
You can cancel or terminate the job by confirming the content and selecting "OK".
