Profile
Research: My major research topic is to develop technologies for runtime systems of parallel programs. Parallel computers have become popular platform from PC servers to large-scale supercomputers. To utilize the computational power of those platforms, users must prepare parallel programs. In an execution of a parallel program on a parallel computer, a runtime system interprets the operation written in the program into specific behavior of the computer. Therefore, technologies in runtime systems are the keys for efficient use of parallel computers. Especially, when the size of the computer becomes large, to achieve better performance, consideration of the information available at runtime, such as the allocation of processes, balance of load among processors or contentions of resources among jobs. In our research, we are developing technologies for dynamic optimization of runtime systems on large-scale parallel computers.

    スーパーコンピュータの大規模化に伴って,ノード間インターコネクトネットワークとして,コストの低い多次元メッシュ/トーラストポロジを採用したものを用いる事例が増えている.多次元メッシュ/トーラスは,使用するノード数が同じでも,プロセスが配置されるノード群の形状によって性能が大きく変動する.本研究では,京コンピュータや,その互換機である FujitsuPRIMEHPC FX10で用いられている Tofuインターコネクトネットワークを対象として,プロセス配置の形状による集団通信アルゴリズムの性能への影響を計測した.得られた性能を,Tofuインターコネクトの性能解析ツールを用いて取得した通信衝突による転送待ち時間と比較したところ,プロセス配置形状による変動がどちらもほぼ同じ傾向を示すことを明らかにした.これらの結果から,集団通信アルゴリズムの選択において,プロセス配置の形状を考慮した性能見

    <p>Turbulent diffusion in homogeneous isotropic turbulence is numerically investigated using the direct numerical simulation (DNS). The four-dimensional turbulence database allows us to track fluid particles not only in the forward direction of time but also in the backward direction. Two-particle dispersion has been studied in previous studies and it is known that backward diffusion is faster than forward diffusion. However, little is known about multi-particle dispersion due to the difficulty of observing it experimentally. Studies on backward diffusion are also limited. In this study, multi-particle dispersion is numerically investigated and its properties are discussed, e.g., direction of time and geometry of a tetrahedron. The results show that forward and backward diffusions of multi-particles behave differently at the beginning and evolve similarly after the transient time, but the coefficients of the backward direction are larger than those of the forward direction.</p>

    In this paper, we discuss the numerical reproducibility of the compressible fluid behavior around two tone holes of woodwind instruments by using compressible Large Eddy Simulation (LES). In particular, we focus on the situation that the tone holes are opened and closed with moving pads above the tone holes, which is regarded as a moving boundary problem with topology change, and reproduce the change of the pitch when opening and closing the tone holes. Our two-dimensional model of a "recorder" has two tone holes. To reproduce the opening and closing the tone holes, the pads are moved continuously. That is, the position of the pads were continuously changed in the order of "open - close". Our numerical results are consistent with the Keef's experimental results. We solved the moving boundary problem with topology change under the situation of acoustics of fluid-structure interaction, and reproduced the pitch change in the opening and closing the tone holes of the recorder like woodwind instrument model.

    Two and three-dimensional models of a test-tube thermoacoustic engine were numerically analyzed using compressible Large Eddy Simulation (LES) to investigate initial transient behavior, i.e., generation mechanism of thermoacoustic waves in an initial state. In the model used in this study, a stack is placed near the bottom of the test-tube and a temperature gradient is applied between both ends of the stack. The model has an external region connecting the opening of the test-tube for radiations of sound waves and heat. As a result, a fluid flow was observed inside the stack, a strong pressure oscillation, i.e., acoustic resonance, was observed inside the test-tube, and sound radiation from the open end was also observed. Furthermore, the frequency of the sound vibration was almost the same as the theoretical estimation of the resonance frequency of the test-tube. Thus, we successfully reproduced the basic properties of the thermoacoustic engine in the initial state. However, noise components increased in time evolution and stationary oscillations were not attained yet. Thus, we need to improve our numerical method. We are also planning to analyze sound waves' generation mechanism taking into account aeroacoustic theory, e.g., Lighthill's acoustic analogy.

  • Aeroacoustic analysis of port noise by using a three-dimensional numerical model of a bass reflex speaker system

    We numerically study port noise observed for a bass reflex speaker system with a compressible fluid solver, Large-Eddy Simulation(LES), to explore the noise generation mechanism from the viewpoint of aeroacoustics. The port noise is considered an aerodynamic sound generated by vortices, created by the interaction between the acoustic field and port opening. However, the detail of the sound generation mechanism is still an open problem. By using a 3D-model, the port-noise is well reproduced by compressible LES, when the speaker system is acoustically driven at its resonance frequency, the Helmholtz resonance frequency of the bass reflex speaker system. Vortices are created near the edges of the port and generate broadband noise. However, noises are enhanced due to resonance in some bands, which correspond to the acoustic resonance frequencies of the port and encloser themselves. We are also planning to investigate the noise generation mechanism by using Howe's energy corollary, which allows us to estimate the energy transfer between fluid dynamics and acoustics, namely we consider the problems of where the aeroacoustic noise is generated and how much energy is transferred from the vortex motions to the acoustic field.

  • Aeroacoustic analysis of oboe reeds with compressible direct numerical simulation

    A two-dimensional model of an oboe reed is studied numerically with a direct numerical simulation (DNS) of the compressible Navier-Stokes equations to investigate the sound generation mechanism from the viewpoint of aeroacoustics. The numerical tool is extremely accurate due to the smallest mesh size on the order of micrometers and successfully reproduces the details of fluid motion and acoustic vibrations inside and outside the reed. Particular attention is paid to the effect of reed vibration on the sound generation mechanism. When the reeds are fixed and a periodically varying flow is injected through the fixed reed slit, an aerodynamics sound created inside the reeds is an almost monotone including a few overtones. On the other hand, when a flow is injected through periodically vibrating reeds from an oral cavity, more overtone components are observed and the pressure waveforms are similar to those observed in the experiment. This indicates that the richness of the overtones of the double-reed instrument is mainly attributed to the aerodynamic sound created by the flow injected through vibrating reeds and the bore, a linear resonator, just enhances characteristics of the instrument, e.g., formant.

    A two-dimensional model of a French Horn mouthpiece is numerically studied with a 2D direct numerical simulation (DNS) of the compressible Navier-Stokes equations to investigate the sound generation mechanism from the viewpoint of aeroacoustics. That is, we consider the sounding mechanism of buzzing, when the mouthpiece without a bore is played. Our numerical tool is highly accurate due to the minimum mesh size of the order of the micro-meter, and details of fluid motion and acoustic oscillation inside and near the mouthpiece are successfully reproduced. In particular, we focus on the roles of vibrating lips and an oral cavity in the sound generation mechanism. When the mouthpiece without lips and an oral cavity is driven by a periodic flow with a certain frequency, a single tone without overtones is observed. On the other hand, when the mouthpiece is driven by vibrating lips with an oral cavity, a generating sound includes rich overtones and its waveform is similar to that observed experimentally. Since the bore is a linear element and cannot generates overtones from a single tone by itself, the sound of a horn including rich overtones is generated by a mouthpiece with the vibrating lips and oral cavity.

  • Numerical study of the feedback mechanism of the edge tone

    We numerically investigate fundamental problems of the edge tone with compressible Large Eddy Simulation (LES) together with acoustic solver FDTD and incompressible LES. Jet oscillation and edge tone in the first mode are successfully reproduced by a 3D model with compressible LES. Namely, the acoustic intensity changes with the jet velocity well following the sixth power law, which is an evidence of the reliability of our numerical method. Next, we estimate the intensity of acoustic feedback in the following way. According to Kaykayoglu and Rockwell, effective pressure sources are considered to be located slightly downstream of the edge tip on both sides of the edge. Indeed, such a pair of positive and negative pressure spots periodically appear in our numerical calculation. Then, we set the pressure spots on both sides of the edge and reproduce acoustic waves radiated from them by FDTD. The acoustic particle velocity of the reproduced acoustic field at the nozzle outlet is regarded as acoustic feedback. Even though such acoustic feedback may make a contribution to driving the jet, we can consider that the fluid feedback is still dominant in a low-Reynolds number regime as pointed out by Paál et al. from the results of incompressible LES.

    スーパーコンピュータの大規模化に伴って,ノード間インターコネクトネットワークとして,コストの低い多次元メッシュ/トーラストポロジを採用したものを用いる事例が増えている.多次元メッシュ/トーラスは,使用するノード数が同じでも,プロセスが配置されるノード群の形状によって性能が大きく変動する.本研究では,京コンピュータや,その互換機である Fujitsu PRIMEHPC FX10で用いられている Tofuインターコネクトネットワークを対象として,プロセス配置の形状による集団通信アルゴリズムの性能への影響を計測した.得られた性能を,Tofuインターコネクトの性能解析ツールを用いて取得した通信衝突による転送待ち時間と比較したところ,プロセス配置形状による変動がどちらもほぼ同じ傾向を示すことを明らかにした.これらの結果から,集団通信アルゴリズムの選択において,プロセス配置の形状を考慮した性能見積もりが重要であることを示した.

    DIMMスロットに装着可能な不揮発性メモリNVDIMMは、DRAMより省電力かつ安価で大容量化が容易なメモリデバイスとして注目されている。本研究では、このNVDIMMを通信ライブラリ内部のバッファ領域として用いる通信レイヤを開発する。これにより、大規模並列計算機での非ブロッキング一対一通信による通信隠蔽が可能となるため、並列アプリケーションのスケーラビリティ向上が期待できる。また、DRAM上バッファとNVDIMM上バッファを、通信頻度等の実行時の状況に応じて切り替えることにより、1~10μ秒と予想されているNVDIMMの遅延時間による性能への影響の軽減を図る。

    将来、スーパーコンピュータの性能向上に向けて計算機のさらなる大規模化が予想されている。しかし、計算機内部の通信を担当する通信ライブラリは、現在の設計のままでは大規模化に伴う使用メモリ量の増加やチューニング作業の複雑化によって、実用性が大幅に低下する。そこで本プロジェクトでは、通信ライブラリが使用する通信バッファ領域を抑えながら、実アプリケーションにおいて数千万~数億プロセスまでの性能向上を維持することを目標とし、その実現に向けて通信ライブラリ実装技術とスケーラブルなアプリケーション作成技術を研究開発する。このうち通信ライブラリ実装技術としては、通信インタフェース、基本通信プロトコル、および通信路制御の各レイヤを対象に、省メモリ化技術と動的最適化技術を研究開発する。

    本研究では、エクサスケール環境においてスケーラビリティ減衰が無いステンシル計算・通信モデルの開発、及びそこで利用されるHalo通信関数の開発を行うことを目的とした。
    まずステンシルシミュレーションにおいて、「計算」と「通信が必要な計算と通信」にスレッドを分けるモデルを開発した。これにより、通信が終わったことを知るための同期が必要無く、並列性能劣化を回避することができた。次に、そこで利用された通信モデルを関数群(Halo関数)にまとめ、他のアプリケーションでも容易に利用可能とした。これらの性能を2000ノード利用した環境で測定を行い、高いスケーラビリティを確認した。
