This article describes how to create an f3 instance.

Note
Due to limited computing resources, we recommend that you use instances with four cores or more for testing, for example, instance type family g5-ecs.g5.2xlarge (8 vCPU core, 32 GiB). Create an f3 instance when you need to download the image to the FPGA chipset.

Prerequisite

The f3 instance type family is currently available for testing by invited users. Open a ticket to request a free f3 instance test.

Procedure

For more information about how to create an f3 instance, see create an ECS instance. When you create an f3 instance, follow these guidelines:

  • Billing Method: Select Pay-As-You-Go or Subscription.
    Note
    • During the testing phase, f3 instances are available for free. Other ECS resources including cloud disks, public network bandwidth, and snapshots will incur usage fees.
    • f3 instances are not available as preemptible instances.
  • Region: Select China East 2 (Shanghai).
  • Instance Type: Select Heterogeneous Computing > FPGA Compute, and then select your required instance type.
  • Image: Click Shared Image, and then select the specified image.
    Note
    We have provided a Xilinx image for development use. At present, the image can only be retrieved through image sharing.
  • System Disk: We recommend that you allocate a 200 GiB Ultra Cloud Disk for the system image.
  • Network: Select VPC.
