Performance Models for Split-execution Computing Systems

Split-execution computing leverages the capabilities of multiple computational models to solve problems, but splitting program execution across different computational models incurs costs associated with the translation between domains. We analyze the performance of a split-execution computing system developed from conventional and quantum processing units (QPUs) by using behavioral models that track resource usage. We focus on asymmetric processing models built using conventional CPUs and a family of special-purpose QPUs that employ quantum computing principles. Our performance models account for the translation of a classical optimization problem into the physical representation required by the quantum processor while also accounting for hardware limitations and conventional processor speed and memory. We conclude that the bottleneck in this split-execution computing system lies at the quantum-classical interface and that the primary time cost is independent of quantum processor behavior.Comment: Presented at 18th Workshop on Advances in Parallel and Distributed Computational Models [APDCM2016] on 23 May 2016; 10 page

Influence of spatial resolution on diurnal variability during the north American monsoon

Diurnal variability is an important yet poorly understood aspect of the warm-season precipitation regime over southwestern North America. In an effort to improve its understanding, diurnal variability is investigated numerically using the fifth-generation Pennsylvania State University (PSU)-NCAR Mesoscale Model (MM5). The goal herein is to determine the possible influence of spatial resolution on the diurnal cycle. The model is initialized every 48 h using the operational NCEP Eta Model 212 grid (40 km) model analysis. Model simulations are carried out at horizontal resolutions of both 9 and 3 km. Overall, the model reproduces the basic features of the diurnal cycle of rainfall over the core monsoon region of northwestern Mexico and the southwestern United States. In particular, the model captures the diurnal amplitude and phase, with heavier rainfall at high elevations along the Sierra Madre Occidental in the early-afternoon that shifts to lower elevations along the west slopes in the evening. A comparison to observations (gauge and radar data) shows that the high-resolution (3 km) model generates better rainfall distributions on time scales from monthly to hourly than the coarse-resolution (9 km) model, especially along the west slopes of the Sierra Madre Occidental. The model has difficulty with nighttime rainfall along the slopes, over the Gulf of California, and over Arizona. A comparison of surface wind data from three NCAR Integrated Sounding System (ISS) stations and the Quick Scatterometer (QuikSCAT) to the model reveals a low bias in the strength of the Gulf of California low-level jet, even at high resolution. The model results indicate that outflow from convection over northwestern Mexico can modulate the low-level jet, though the extent to which these relationships occur in nature was not investigated. © 2008 American Meteorological Society

Kajian Studi Kelayakan Sungai Sail untuk Ketersediaan Air Baku di Kecamatan Bukit Raya Kota Pekanbaru

The Regional Water Company (PDAM) has not been able to providing clean water in the city of Pekanbaru, one of which is the Bukit Raya subdistrict because of the many obstacles faced such as leaking pipes, the age of the pipe that is very old, and the quality of the Siak River water had been contaminated by heavy metals. So it is necessary to study the potential for surface water sources that could be developed, one of which is Sail River considered potentially to be used as a source of raw water. This study aims to determine the quantity of river discharge associated mainstay of Sail River, Sail river water balance and determine the quality of Sail River that can be used as a raw water source, in this case water providers to meet the needs of Bukit Raya subdistrict.The results of the calculation, 95% of the river discharge mainstay Sail River of 0,21 m3/sec. Clean water needs of domestic and non domestic in 2033 amounted to 0.283 m3/sec. Based on the amount of discharge is available on the river and the need for clean water is known Sail River water balance have deficit water amounted to -0,073 m3/sec. Results of laboratory tests of water quality in mind some of the parameters that does not comply with quality standards, such as pH, BOD, COD, DO, NH3, nitrogen, iron, sulfur as H2S, and total coliform. Therefore, to take advantage of Sail River as raw water treatment is required in advance

Efektivitas Media Animasi terhadap Hasil Belajar Biologi Siswa SMPN 2 Kediri

The use of instructional media is essential for understanding Biology. This study aims to determine the effectiveness of the use of animation media on learning outcomes. The study was conducted with quasi-experimental and non-equivalent pre-test-post-test control group designs. Data were taken from the pre-test, post-test and gain scores. The research instrument is a written test in the form of multiple choice questions. Data were analyzed using \u27mean difference test\u27. The results showed that the results of the study on sub photosynthesis and respiration material differed significantly. The gain analysis shows that the animation media has improved student learning outcomes

Pengaruh Jenis Elektroda Terhadap Sifat Mekanik Hasil Pengelasan Smaw Baja Astm A36

Penggunaan elektroda dan arus yang berbeda pada proses pengelasan berpengaruh terhadap sifat fisik dan mekanik hasil lasan. Penelitian ini bertujuan untuk mengetahui hasil lasan, struktur mikro, distribusi kekerasan dan kekuatan tarik terhadap penggunaan jenis elektroda dan arus pengelasan. Baja ASTM A36 dilakukan pengelasan SMAW menggunakan elektroda E6013, E7016 dan E7018 dengan arus 70A, 110A dan 130A pada kecepatan konstan. Hasil pengelasan dilakukan analisa struktur makro, struktur mikro, kekerasan dan kekuatan tarik. Arus pengelasan berpengaruh terhadap karateristik makro, struktur mikro, distribusi kekerasan dan kekuatan tariknya. Semakin tinggi arus yang dipakai semakin rendah nilai kekerasan dan kekuatan tarik. Hasil yang didapat pada perbedaan elektroda nilai kekerasan yang paling tinggi menggunakan elektroda E7018 dengan variasi arus 70A yaitu 105 HRB, dan nilai tertinggi pada pengujian tarik pengelasan menggunakan elektroda E6013 dengan variasi arus 110A yaitu 34,697MPa

Perencanaan Kolam Retensi pada Perumahan Mutiara Witayu Kecamatan Rumbai Koata Pekanbaru

Flooding in Mutiara Witayu Recidence caused a big problem for the local communities. This situation led the government taking an action to relocate and plan a construction of retention pond as a settlement of the flood in the region. The purpose of this study was to get a sufficient retention pond capacity to accommodate the flood discharge at the sites. During it's planning, hydrological analysis was conducted with rainfall data from the Office of Hydrology station for 20 years. Log Person III probability distribution and 5 year retense were used for the analysis. EPA SWMM program was used to analyze the flow of runoff existing in this study. The flooding problem was due to the runoff water which could not flow out into the outfall caused by the operation of the sluice. So it was necessary to accommodate the construction of retention pond during the discharge of the runoff of rainwater. The retention pond with a capacity of 23,000 m3 with a maximum depth of 1 m and ponded area of 23,000 m2, was planned in the study site. Based on the running program, it was found that the addition of a retention pond with that capacity could effectively accommodate the flood discharge at the sites. The cost required to build retention pond was Rp. 7,810,000,700.00 (Seven Billion Eight Hundred and Ten Million Seven Hundred Rupiahs)
