manio-org.github.io

Build a Jekyll blog in minutes, without touching the command line.

mcast-group-management

a resource manager for resource of multicast.

metasim

Metasim is used to simulate metadata behaviors in PLFS (Parallel Log-structured File System) and beyond. It is a platform for explorations.

mysql-io-pattern

In this project we study the I/O pattern (system call level) of MySql.

plfs-core

PLFS is a parallel virtual file system that rearranges random, concurrent writes into sequential writes to unique files (i.e. N-1 into N-N). Available under LANL LA-CC-08-104.

plfs-map-replayer

This little program reads the output of plfs_map (of the PLFS project) and replays the writes. Note that the timestamp is ignored. It just does it one by one from top to the bottom.

py-cpp-io-perf

Some code to compare Python and C++ IO performance.

pyfallocate

pyfallocate allows Python script to call Linux fallocate().

python-patterns

A collection of design patterns/idioms in Python

The original QIO uses C lib I/O calls. This little project is to change it to use POSIX calls (open, write,.. ) and MPI-IO calls (MPI_File_*). Doing this is because using C lib I/O causes problem on PLFS. Please find the code using POSIX (open, write..) in branch posix, the code using MPI-IO in branch mpiio.

redis

Redis is an in-memory database that persists on disk. The data model is key-value, but many different kind of values are supported: Strings, Lists, Sets, Sorted Sets, Hashes, HyperLogLogs, Bitmaps.
