A C++-embedded Domain-Specific Language for programming the MORA soft processor array
No full textMORA is a novel platform for high-level FPGA programming of streaming vector and matrix operations, aimed at multimedia applications. It consists of soft array of pipelined low-complexity SIMD processors-in-memory (PIM). We present a Domain-Specific Language (DSL) for high-level programming of the MORA soft processor array. The DSL is embedded in C++, providing designers with a familiar language framework and the ability to compile designs using a standard compiler for functional testing before generating the FPGA bitstream using the MORA toolchain. The paper discusses the MORA-C++ DSL and the compilation route into the assembly for the MORA machine and provides examples to illustrate the programming model and performance
MARGINAL PRODUCTIVITY INDEX POLICIES FOR SCHEDULING A MULTICLASS DELAY-/LOSS-SENSITIVE QUEUE
No full textWe address the problem of scheduling a multiclass M/M/1 queue with a finite dedicated buffer for each class. Some classes are delay-sensitive, modeling real-time traffic (e.g. voice, video), whereas others are loss-sensitive, modeling nonreal-time traffic (e.g. data). Different levels of tolerance to delay and loss are modeled by appropriate linear holding cost and rejection cost rates. The goal is to design well-grounded and tractable scheduling policies which nearly minimize the discounted or long-run average expected cost objective. We develop new dynamic index policies, prescribing to give higher service priority to classes with larger index values, where the priority index of a class measures the marginal productivity of work at its current state. To construct the indices, we deploy the theory of marginal productivity indices (MPIs) and PCLindexability we have introduced in recent work, and further introduce significant extensions to such theory motivated by phenomena observed in the model of concern. The MPI policies are shown to furnish new, insightful structural results, and to exhibit a nearly optimal performance in a computational study.
Convergence of equilibria of thin elastic plates under physical growth conditions for the energy density
No full textThe asymptotic behaviour of the equilibrium configurations of a thin elastic plate is studied, as the thickness of the plate goes to zero. More precisely, it is shown that critical points of the nonlinear elastic functional converge to critical points of the Γ-limit. This is proved under the physical assumption that the energy density blows up as the determinant of the deformation gradient becomes infinitesimally small

Progetto 16. Tempus - IDELE: Innovation and Development in Spanish as a Second Language. Progetto n° 530459-TEMPUS-1-2012-1-ES-TEMPUS-JPCR, coordinato dall’Universidad de Salamanca
No full textM. J. Rodrigo Mora è Coordinatrice scientifica per l’Università di Bologna del Progetto 16. Tempus - IDELE: Innovation and Development in Spanish as a Second Language. Progetto n° 530459-TEMPUS-1-2012-1-ES-TEMPUS-JPCR, coordinato dall’Universidad de Salamanca.
Il progetto si propone di contribuire alla modernizzazione del sistema di istruzione superiore egiziano, in particolare per quanto concerne l’insegnamento della lingua spagnola, tramite la formazione di insegnanti locali e la creazione di un corso di Master per l’insegnamento della lingua spagnola presso i partner locali egiziani.
Il progetto prevede un budget totale di € 893.042,85 di grant. Il budget massimo assegnato ad UNIBO è di € 66.396 Euro. Il co-finanziamento del progetto, da ripartirsi tra i partner partecipanti, sarà coperto – per quanto riguarda la quota UNIBO – attraverso la valorizzazione dei costi del personale docente e tecnico-amministrativo strutturato.
La coordinatrice scientifica del progetto per l’Università di Bologna è la Prof.ssa Maria José Rodrigo Mora. La gestione contabile del progetto sarà in capo al Dipartimento di Lingue, Letterature e Culture Moderne, pertanto il finanziamento sarà introitato direttamente sul budget del Dipartimento che predisporrà la rendicontazione finale del progetto per la quota assegnata all’Università di Bologna
Restless bandit marginal productivity indices I: singleproject case and optimal control of a make-to-stock M/G/1 queue
No full textThis paper develops a framework based on convex optimization and economic ideas to formulate and solve by an index policy the problem of optimal dynamic effort allocation to a generic discrete-state restless bandit (i.e. binary-action: work/rest) project, elucidating a host of issues raised by Whittle (1988)Žs seminal work on the topic. Our contributions include: (i) a unifying definition of a projectŽs marginal productivity index (MPI), characterizing optimal policies; (ii) a complete characterization of indexability (existence of the MPI) as satisfaction by the project of the law of diminishing returns (to effort); (iii) sufficient indexability conditions based on partial conservation laws (PCLs), extending previous results of the author from the finite to the countable state case; (iv) application to a semi-Markov project, including a new MPI for a mixed longrun-average (LRA)/ bias criterion, which exists in relevant queueing control models where the index proposed by Whittle (1988) does not; and (v) optimal MPI policies for service-controlled make-to-order (MTO) and make-to-stock (MTS) M/G/1 queues with convex back order and stock holding cost rates, under discounted and LRA criteria
RESTLESS BANDIT MARGINAL PRODUCTIVITY INDICES II: MULTIPROJECT CASE AND SCHEDULING A MULTICLASS MAKE-TO-ORDER/-STOCK M/G/1 QUEUE
No full textThis paper develops a framework based on convex optimization and economic ideas to formulate and solve approximately a rich class of dynamic and stochastic resource allocation problems, fitting in a generic discrete-state multi-project restless bandit problem (RBP). It draws on the single-project framework in the author´s companion paper “Restless bandit marginal productivity indices I: Single-project case and optimal control of a make-to-stock M/G/1 queue”, based on characterization of a project´s marginal productivity index (MPI). Our framework significantly expands the scope of Whittle (1988)´s seminal approach to the RBP. Contributions include: (i) Formulation of a generic multi-project RBP, and algorithmic solution via single-project MPIs of a relaxed problem, giving a lower bound on optimal cost performance; (ii) a heuristic MPI-based hedging point and index policy; (iii) application of the MPI policy and bound to the problem of dynamic scheduling for a multiclass combined MTO/MTS M/G/1 queue with convex backorder and stock holding cost rates, under the LRA criterion; and (iv) results of a computational study on the MPI bound and policy, showing the latter´s near-optimality across the cases investigated.
