The present disclosure relates to a plurality of host materials comprising at least one first host compound represented by formula 1 and at least one second host compound represented by formula 2, and an organic electroluminescent device comprising the same. By comprising the host materials according to the present disclosure, an organic electroluminescent device having low driving voltage and/or high luminous efficiency and/or long lifespan can be provided.

Plurality of host materials and organic electroluminescent device comprising the same

A multi-processor system includes a plurality of processors, a scheduler, and a selector. Each of the plurality of processors is included in at least one of a plurality of domains. The plurality of domains include three or more domains and are defined based on a hierarchical domain structure. The scheduler receives and manages at least one task performed by the plurality of processors. The selector selects one of the plurality of domains based on states of the plurality of domains to assign the at least one task to the selected domain, and selects at least one processor among processors in the selected domain based on states of the processors in the selected domain to assign the at least one task to the selected processor, when the at least one task is received.
