설치 문서를 보고 있는데 역시 개인이 가볍게(?) 설치할 만한 규모가 아니다.

 

문서에서는 최소 5대를 가지고 설치해야 하는데

그나마도 lustre같은 파일 시스템이 아닌 nfs로 구성하는 것이고

lustre나 BeeGFS 분산파일 시스템 추가되면 최소 2대 이상이 더 필요해진다.

 

마스터 노드와 컴퓨트 노드 총 5대로 구성을 하고

마스터 노드는 SMS(System Management Server)와 프로비저닝(warewulf)을 제공한다.

1.2 Requirements/Assumptions
This installation recipe assumes the availability of a single head node master, and four compute nodes.The master node serves as the overall system management server (SMS) and is provisioned with CentOS 8.2 and is subsequently configured to provision the remaining compute nodes with Warewulf in a stateless configuration. The terms master and SMS are used interchangeably in this guide. For power management, we assume that the compute node baseboard management controllers (BMCs) are available via IPMI from the chosen master host. For file systems, we assume that the chosen master server will host an NFS file system that is made available to the compute nodes. Installation information is also discussed to optionally mount a parallel file system and in this case, the parallel file system is assumed to exist previously

 

HPC systems rely on synchronized clocks throughout the system and the NTP protocol can be used to facilitate this synchronization

호스트 IP를 비워두니 작동을 안한다.

localhost로 될진 모르겠지만 IP 라고 하니 일단은 127.0.0.1로 입력하니 작동함

특이하게 파일 - 네트워크 작업 관리자가 아니라

파일 - 환경설정으로 가야하네?

 

 

 

가상머신 설정

 

이렇게 설정해주면 다른 가상머신도

virtualbox의 NAT network 하나에 연결이 된다.

warewulf는 단순하게 구성된 provisioning 툴이라고 한다.

프로비저닝은 OS를 구성하고 네트워크 부트를 지원해야 하는데

warewulf 종속성으로 dhcpd나 tftp 등도 다 설치하게 되려나?

fft

이산 코사인 변환 DCT(discrete cosine transform)

이산 푸리에 변환 DFT(discrete Fourier transform)

 

type-II DCT DCT

type-III DCT 역DCT, IDCT

 

실수 신호에 대하여, 변환 결과물이 복소수로 나오는 DFT

DCT는 실수로만 결과물이 나오기 때문에, 처리하기가 간편하여 신호처리 및 영상처리에 널리 사용

~/src/ffmpeg$ ./configure 
nasm/yasm not found or too old. Use --disable-x86asm for a crippled build.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

예전에 찾은적이 있네..

fft를 위한 라이브러리인데 도대체 어떤 함수를 써서 분석을 하고

주파수 대역은 어떤식으로 맵핑이 가능한건질 모르겠다.

OpenHPC는 Provisioning / Resource Manager / MPI 등의

여러가지 패키지를 포함하는 HPC 구성용 배포판 이라고 해야하나? (OpenSUSE, CENTOS 기반)

 

OpenHPC software packages
OpenHPC divides its software packages into different functional areas, and each includes multiple components:

Provisioning: Warewulf, xCAT
Resource management: Slurm, Munge, PBS Professional
Runtimes: OpenMP, OCR, Singularity
Numerical/scientific libraries: GSL, FFTW, Metis, PETSc, Trilinos, Hypre, SuperLU, Mumps, OpenBLAS, Scalapack
I/O libraries: HDF5, NETCDF, Adios
Compilers: GCC, LLVM
MPI families: MVAPICH2, Open MPI, MPICH
Performance tools: PAPI, IMB, mpiP, pdtoolkit, TAU, Scalasca, ScoreP, SIONLib

좀 놀라운 사실이네.. 그나저나 MPICH를 검색하니 vs openmpi가 나오고 그러네..

 

아무튼 beowulf cluster를 만드는데 여러가지 것들이 들어갔지만 공식적으로

beowulf라는 프로그램이 없다는건 좀 신선하네..

MPICH와 같은 Message Passing Interface 기반의 분산 병렬 처리가 핵심이고

3. Where can I get the Beowulf software?
There isn't a software package called "Beowulf". There are, however,several pieces of software many people have found useful for building Beowulfs. None of them are essential. They include MPICH, LAM, PVM, the Linux kernel, the channel-bonding patch to the Linux kernel (which lets you 'bond' multiple Ethernet interfaces into a faster 'virtual' Ethernet interface) and the global pid space patch for the Linux kernel (whichlets you see all the processes on your Beowulf with ps, and eliminate them), DIPC (which lets you use sysv shared memory and semaphores and message queues transparently across a cluster).

MPI까진 있는데 MPICH는 모르겠네...

[링크 : https://www.mpich.org/]

 

Message-Passing Interface Chameleon

PVM(Parallel Virtual Machine)

LAM-MPI ?

일단은 마이크로 raw audio나 wav를 받아서 분석하는걸 찾아봐야겠다.
