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?

~/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.

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...

일단은 마이크로 raw audio나 wav를 받아서 분석하는걸 찾아봐야겠다.

OpenHPC는 all in one
Slurm 이나 PBS Pro 는 Job Scheduler로 구분된다.

OpenHPC, xCAT, Warewulf 가 클러스터 관리 프로그램으로 분류된다.

Warewulf is a scalable systems management suite

beowulf와 warewulf의 연관이나 차이점은 검색이 쉽지 않네..

OpenHPC도 내부적으로는 Warewulf + OpenPBS / Slurm 으로 구성되는 듯(설치문서)
