Analysis and optimization of storage IO in distributed and massive parallel high performance systems [article]

Salem El- Sayed Mohamed, Universität Stuttgart, Universität Stuttgart
2012
Although Moore's law ensures the increase in computational power, IO performance appears to be left behind. This minimizes the benefits gained from increased computational power.  ...  Another factor that slows the IO communication is the increased parallelism required in today's computations. Most modern processing units are built from multiple weak cores.  ...  Another typical brilliant implementation for which the Linux Kernel can be appreciated is the fact of it being object oriented.  ...
