Optimizing Parallel Reduction In Cuda To Reach GPU Peak Performance

GPUs are massively multi threaded many core chips that have hundreds of cores and thousands of concurrent threads swith high performance and memory bandwidth. Now days, GPUs have already been used to accelerate some numerically intensive high performance computing applications in parallel not only used to graphic processing. This thesis aims primarily to demonstrate the programming model approaches that can be maximize the performance of GPUs. This is accomplished by a proof of maximum reach of bandwidth memory and get speed up from the GPU that used to process parallel computation. The programming environment that used is NVIDIA’s CUDA, it is parallel architecture and model for generalpurpose computing on a GPU

Designing a drilled pile foundation in a dual system structure

Drilled pile foundations that have been set in hard soil are generally used for buildings with shear walls. By nature, a drilled pile foundation can withstand moments because of the drilled pile’s dimensions and the amount of reinforcement installed. This study presents a structural analysis of a 10-story building supported by a dual system structure to meet earthquake requirements. The results show that, by using a dual system, the earthquake requirements (natural period, modal, story shear, story drift, and P-Delta) are met. Other results show that the base shear force of the shear wall has a value of 58.76% for the X-direction and 63.72% for the Y-direction. The base shear force value of the frame is 41.23% for the X-direction and 36.27% for the Y-direction. Therefore, the requirements of the dual system are met because the resisted base shear force of the frame is higher than 25%. The dual system provides a normal force value of 24.32% for the shear wall, while the frame carries 75.67%. The bearing capacity of the drilled pile with a safety factor = 2.5 is 162 tons for a diameter of 50 cm, 214 tons for a diameter of 60 cm, 340 tons for a diameter of 80 cm, 493 tons for a diameter of 100 cm, 672 tons for a diameter of 120 cm, and 993 tons for a diameter of 150 cm. The result of the pile driving analyzer test values for a 120 cm diameter range from 988 to 1,232 tons

OPTIMIZATION OF OXYGEN.ID SERVICE WITH THE IMPLEMENTATION OF HIGH AVAILABILITY ROUTER HOTSPOTS AND TRANSPARENT BANDWIDTH MANAGEMENT ROUTERS: A CASE STUDY OF PT. INDONESIAN TELEMATICS MORA

With the increasing demand for public free WIFI hotspot service Oxygen.id causes increased traffic in accessing the free WIFI hotspot Oxygen.id service, which of course can result in decreased access performance for customers. By applying The Virtual Router Redundancy Protocol (VRRP) router method and simple bandwidth management queuing to fix existing problems, an additional load simulation of 1450 bytes was carried out from the PING status on the CMD window, the results found that the VRRP hotspot was still stable compared to the existing hotspot. and at the time of testing the mp4 file download process was 17,555KB. The resulting VRRP hotspot output is 673 kbyte, which is bigger than the existing thinkput hotspot, which is 495 kbyte, while the delay result is smaller for VRRP hotspot 35,422 compared to delaying the existing hotspot, which is 39,693 seconds, with the results of this study proven completion in overcome the traffic of serving the free oxygen.id hotspot wifi which is getting higher and highe

COMPARATIVE ANALYSIS OF MAMDANI AND SUGENO'S FUZZY INFERENCE METHOD ON ROOM LIGHT CONTROL PROTOTYPE

Fuzzy Logic can be applied to the field of control systems. The advantage of using Fuzzy Logic is that it is easy to calculate because it combines mathematical equations and natural language. Therefore, Fuzzy Logic overcomes the weakness of the On/Off control system. Likewise, Fuzzy Logic overcomes the complexity of mathematical modeling on PID control. However, Fuzzy Logic is not suitable to be applied to control systems that require high accuracy. In this study, Fuzzy Logic will be applied to the control of room light, where in the room there are two light sources, namely lamp light and outside light. The problem is how the room light illuminance is always in the set point range with a tolerance of 25 lux and in steady state conditions. The application of light control is appropriate because it does not require high accuracy where a slight change in light illuminance has no effect. In this study, a comparison was made between the Mamdani and Sugeno inference methods. The limitation of control parameters is on the response of the control system to the set point. The results obtained are the control system response shows that there is a smaller error in the Sugeno method than the Mamdani method
