In this paper, we discuss a set of approaches to optimization of the memory access behavior of the applications, which enable their executions with improved performance on the recent HPC systems. 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 benchmark verificationThe 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 benchmark generatorThis 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. FSR 2.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.

FireStream 9270 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The GPU is operating at a frequency of 750 MHz, memory is running at 900 MHz (3.6 Gbps effective).īeing a dual-slot card, the AMD FireStream 9270 draws power from 2x 6-pin power connectors, with power draw rated at 160 W maximum. AMD has paired 2,048 MB GDDR5 memory with the FireStream 9270, which are connected using a 256-bit memory interface. It features 800 shading units, 40 texture mapping units, and 16 ROPs. The RV770 graphics processor is an average sized chip with a die area of 256 mm² and 956 million transistors. Since FireStream 9270 does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. Built on the 55 nm process, and based on the RV770 graphics processor, in its RV770 XT variant, the card supports DirectX 10.1. #Amd firestream 9370 benchmark professionalThe FireStream 9270 was a professional graphics card by AMD, launched on November 13th, 2008.
