The Goal

All in one cluster Energy efficient Cost effective Foundation for

future work Multipurpose

System

HPCHPC

Computing Centers− Mainframes− Supercomputers

PC− Computing

Centers to Computer Labs

− HPC is still needed

ClustersClusters

Used in many fields− Engineering− Physics− Economics

Complicated to design and build

5

MPI and Linux

MPI the main tool for cluster programming

Linux is the main OS of clusters

Both inefficient Linux Kernel

15.9 million lines of code
