Compute maps are created during system initialization, not by users. A compute map is an instance type defined by the resources used in it, such as the following:
- AMPsPerNode = n, AMPs per node
- NodeCount = n, Total number of nodes
- MemoryPerNode = n, Memory in gigabytes (GB) per Node
- CPUsPerNode = n, Number of CPUs per Node
- NodeType = 'cloud_template', Cloud template used for this configuration. For example, small, medium,large, xlarge, 4xlarge, and so on
- MIPSPerCPU = n, Millions of Instructions per Second per CPU
Where n is an integer value between 1 and 32767.
Compute maps are named and are used in compute profiles.
For example, a compute map configuration can be as follows:
- AMPsPerNode = 2
- NodeCount = 3
- MemoryPerNode = 250
- CPUsPerNode = 10
- NodeType = m5d.4xlarge
- MIPSPerCPU =100
To see the available compute maps and their details, run:
SELECT * FROM DBC.COGMAPSV ORDER BY NodeCount;
