UpStare 0.10.9 (Default branch)
UpStare is a dynamic software updating system (compiler, runtime, and patch-generator) for multi-threaded userspace applications. It allows semi-automatic updates to programs that could not be updated with existing approaches, or could be updated with a possibly indefinite delay between the time an update is requested and the time the update is applied. The approach can replace functions active on the stack by applying stack reconstruction, which can update program state and program code immediately in a single step. This obviates the need to rely on statically determined safe update points, which might not exist, and can update server-side code without closing client connections.License: Free for non-commercial useChanges:
This release considerably improves the ability of the patch generator to automatically produce stack transformers and incorporate user-defined stack transformers. It also implements support for blocking system calls in a much more efficient way.Image

libmlib_mt

libmlib_mt(3LIB)														  libmlib_mt(3LIB)

NAME

       libmlib_mt - multi-threaded mediaLib

SYNOPSIS

       cc [ flag... ] file... -lmlib_mt -lmlib [ library... ]
       #include <mlib.h>

       Interfaces  in  this library provide functions for multimedia processing. Multi-threaded (MT) mediaLib is a software layer developed on top
       of mediaLib using OpenMP.  When it is used with a large data set on a multi-processor system, MT mediaLib will partition data into  subsets
       and process the subsets in parallel, thus greatly improving performance of applications that use mediaLib.

INTERFACES

       The shared object libmlib_mt.so.2 provides the same public interfaces as those defined in libmlib(3lib). See intro(3) for additional infor-
       mation on shared object interfaces.

       There are two ways to use MT mediaLib.

       1.  Pre-load a multi-threaded mediaLib library during runtime by setting the LD_PRELOAD environment variable  as  follows  before  starting
	   your application, in Bourne/Korn shell:

	   LD_PRELOAD=libmlib_mt.so
	   export LD_PRELOAD

	   or in C shell:

	   setenv LD_PRELOAD libmlib_mt.so

	   In this way, you can take advantage of MT mediaLib without rebuilding your application.

       2.  Link  your  application with a multi-threaded mediaLib library directly as shown under .  In this way, an MT mediaLib library is always
	   used whenever your application is started.

       The parallelization of MT mediaLib is controlled, in part, by the PARALLEL environment variable.  You can change its setting to adjust  the
       degree of parallelization before starting your application,  in Bourne/Korn shell:

       PARALLEL=n
       export PARALLEL

       or in C shell:

       setenv PARALLEL n

       where n is a positive integer for number of threads. Note that other factors also affect the degree of parallelization in MT mediaLib.

       /usr/lib/libmlib_mt.so.2        shared object

       /usr/lib/64/libmlib_mt.so.2     64-bit shared object
