Methods and modules relating to allocation of host machines

A non-transitory computer-readable storage medium having stored there on computer readable code which, when executed on a Weight Generating Module for generating a respective set of weights representing a respective policy out of a plurality of policies, wherein the respective set of weights defines a respective allocation of a respective host machine obtained from a hardware system, wherein the hardware system comprises a memory pool, comprising memory units, and a Central Processing Unit (CPU) pool, comprising CPUs, wherein a total number of pairs of groups, comprising the CPUs and memory units, are associated with latencies, each of the latencies indicating a respective latency between a respective group of CPUs and a respective group of memory units, wherein the respective policy is defined by a respective set of user-defined weights relating to a number of collections of the pairs, wherein the respective policy is associated with a respective allocation weight relating to requests for the respective allocation of the respective host machine, causes the Weight Generating Module to perform operations comprising:

• calculating a respective user-defined number of pairs for each collection of the number of collections by distributing the total number of pairs among the number of collections for each respective policy based on the respective set of user-defined weights and the respective allocation weight;
• selecting, for said each collection, the respective user-defined number of pairs from among the total number of pairs in increasing order with respect to the latencies to obtain a respective sub-set of collection weights relating to latencies associated with said each collection, wherein a set of collection weights comprises each of the respective sub-sets of collection weights;
• determining, for said each respective policy, the respective set of weights representing the respective policy based on the set of collection weights;
• and
• providing, for said each respective policy, the respective set of weights.

A Weight Generating Module configured for generating a respective set of weights representing a respective policy out of a plurality of policies, wherein the respective set of weights defines a respective allocation of a respective host machine obtained from a hardware system, wherein the hardware system comprises a memory pool, comprising memory units, and a Central Processing Unit (CPU) pool, comprising CPUs, wherein a total number of pairs of groups, comprising the CPUs and memory units, are associated with latencies, each of the latencies indicating a respective latency between a respective group of CPUs and a respective group of memory units, wherein the respective policy is defined by a respective set of user-defined weights relating to a number of collections of the pairs, wherein the respective policy is associated with a respective allocation weight relating to requests for the respective allocation of the respective host machine, wherein the Weight Generating Module is configured for comprising:

• a processor;
• and
• a memory containing instructions which, when executed by the processor, cause the Weight Generating Module to perform operations to:
• calculate a respective user-defined number of pairs for each collection of the number of collections by distributing the total number of pairs among the number of collections for each respective policy based on the respective set of user-defined weights and the respective allocation weight;
• select, for said each collection, the respective user-defined number of pairs from among the total number of pairs in increasing order with respect to the latencies to obtain a respective sub-set of collection weights relating to latencies associated with said each collection, wherein a set of collection weights comprises each of the respective sub-sets of collection weights;
• determining, for said each respective policy, the respective set of weights representing the respective policy based on the set of collection weights;
• and
• providing, for said each respective policy, the respective set of weights.
