Parameters | Definition |
|---|---|
\( {x^{\prime}}_{r,{n}_h}^{m_t} \) | Number of type r VMs of server mt assigned to serve job nh at the current time slot. |
\( {N}_h^{\prime } \) | Total number of current type h jobs |
\( {\nu^{\prime}}_{n_h}^r \) | Number of type r VMs required by job nh at current time slot left in the system. |
\( {x^{\prime}}_{r,{n}_h}^{j_t} \) | Number of type r VMs serving job nh on a type t server with pattern jt at current time slot |
\( {m^{\prime}}_{\ell, e}^{j_t} \) | Number of active type t servers with pattern jt in the rack of pod ℓ at the current time slot. |
\( {\varphi^{\prime}}_{\ell, e}^{f,{j}_t} \) | Binary variable denoting whether type t server on rack e in pod ℓ which has pattern jt at current time slot is active or not. |
G r | Power consumption related to the migration of type r VMs |
\( {x}_{r,h}^{{\overset{\sim }{I}}_t} \) | Number of type r VMs assigned to type h jobs over the server type t by the initialization pattern \( {\overset{\sim }{I}}_t \). |
R h | Different VM types demanded by type h jobs. |
