receive, from a respective host computer, data regarding at least one virtual processor associated with a NUMA node operating in the respective host computer;
receive a virtual processor requirement of a client to be placed in one of the plurality of host computers of the distributed computer system; and
determine a target host computer of the distributed computer system for placing the client based on the data regarding the at least one virtual processor in the respective host computer of the distributed computer system and the virtual processor requirement of the client to be placed.
9. The non-transitory computer-readable storage medium of claim 8 , wherein the data regarding the at least one virtual processor associated with the NUMA node further includes at least one physical processor associated with the NUMA node operating in the respective host computer.
10. The non-transitory computer-readable storage medium of claim 8 , wherein the at least one virtual processor represents an average quantity of virtual processors operating for the NUMA node for a predefined period of time.
11. The non-transitory computer-readable storage medium of claim 8 , wherein transmitting the query for NUMA data to the plurality of host computers of the distribution computer system is performed in an instance in which a generation of the client in the distributed computer system has occurred.
12. The non-transitory computer-readable storage medium of claim 8 , wherein the executable instructions are further configured to cause the computing device to at least:
determine a NUMA score for the NUMA node associated with the respective host computer based on a virtual and physical processor ratio associated with the NUMA node.
13. The non-transitory computer-readable medium of claim 12 , wherein the determining the NUMA score for the NUMA node associated with the respective host computer further comprises selecting a maximum value from the virtual and physical processor ratio for the respective host computer.
14. The non-transitory computer-readable medium of claim 12 , wherein the determining the NUMA score for the NUMA node associated with the respective host computer further comprises determining a k-th percentile of the virtual and physical processor ratio for a particular host computer, where k is a number less than 100.
15. A system, comprising:
a computing device that comprises a processor and memory; and
program instructions executable in the computing device that, when executed by the computing device, cause the computing device to at least:
