To fully exploit the potential of the recent HPC systems, and to meet the increasing demand for large memory, it is necessary to optimize practical scientific and engineering applications, considering not only the parallelism of the applications, but also the limitations of the memory subsystems of the HPC systems. The bytes per flop (B/F), which is a ratio of the memory bandwidth to the flop/s, for the HPC systems have been reduced with the evolution of the HPC systems. Most recent HPC systems adopt a parallel processing architecture, where the computational capability of the processors is increasing, however, the performance of the memory system is constrained.
Since recent scientific and engineering simulations require heavy computations with large volumes of data, High-performance Computing (HPC) systems need a high computational capability with a large memory capacity. An example which illustrates the application of the mentioned methods is described.
Amd firestream 9370 verification#
The first one automatically generates the replacement operation in ACL2 language, the second one automatically generates auxiliary lemmas which allow to prove the obtained verification conditions in ACL2 successfully in automatic mode. To prove verification conditions automatically in ACL2, two algorithms were developed and implemented.
Amd firestream 9370 generator#
This rule was implemented in verification conditions generator which is a part of the automated system of C-light program verification. The method contains the inference rule for iterations without loop invariants. This extension includes the verification method of iterations over changeable arrays possibly with loop exit in C-light programs. It extends the mixed axiomatic semantics method suggested for C-light program verification. This work represents the further development of this method.
This operation expresses loop effect in a symbolic form and allows to introduce an inference rule which uses no invariants in axiomatic semantics. Its idea is to represent a loop body in a form of special replacement operation under certain constraints. An alternative is the symbolic method of loop invariant elimination suggested by V.A. As a rule, the methods of invariant synthesis are heuristic ones. Several AMD technology partners and OEMs plan to offer rack mounted servers and expansion systems featuring AMD FireStream 93 accelerators, including One Stop Systems and Supermicro.During deductive verification of programs written in imperative languages, the generation and proof of verification conditions corresponding to loops can cause difficulties, because each one must be provided with an invariant whose construction is often a challenge. With up to 2.64 TFLOPS of compute power, the new AMD FireStream accelerators are ideal for HPC, cloud and enterprise-scale deployments that require advanced performance for handling today’s highly parallel, compute-intensive workloads. Power consumption has been set to maximal 150 watt.īoth graphics cards will become available ine Q3 2010, but the prices were not revealed.
Little brother AMD FireStream 9350 ships in a single-slot design and settles for 2GB GDDR5 memory, and slightly slower performance 400 gigaflops at double precision and 2.0 teraflops at single-precision. The graphics card ships in a dual-slot design and consumes at most 225 watt. AMD FireStream 9370 is the name of the top model sporting 4GB GDDR5 memory, supporting DirectX 11, OpenCL, Direct Compute and offering 528 gigaflops double precision performance and 2.64 teraflops at single precision.
