Practical threaded programming with Python

Jun 3, 2008 ... Threaded programming in Python can be done with a minimal amount of
complexity by combining threads with Queues. This article explores using
threads and queues together to create simple yet effective patterns for solving
problems that require concurrency.

Charming Python: Implementing "weightless threads" with Python ...

Jun 1, 2002 ... The example illustrates one reasonable technique for eventual termination of the
scheduler loop. A special generator/thread, quitter() , monitors some condition (in
this case, just a count of context switches) and throws a StopIteration when it is
satisfied (other exceptions are not caught in the example).

Multiprocessing with Python

Mar 24, 2009 ... In a previous article for IBM® developerWorks®, I demonstrated a simple and
effective pattern for implementing threaded programming in Python. One
downside of this approach, though, is that it won't always speed up your
application, because the GIL (global interpreter lock) effectively limits threads to ...

Is Python Slow As Molasses? (IT Best Kept Secret Is Optimization)

Jan 23, 2017 ... Jack Vanderplas gives a compelling example of how the combination of Numba
and Numpy can lead to code that runs almost as fast as Fortran in Optimizing
Python in the Real World: ... The most important one is that Python can only
execute one thread at a time, because of the global interpreter lock (GIL).

How To Make Python Run As Fast As Julia (IT Best Kept Secret Is ...

Dec 1, 2015 ... The first question that came to my mind was different however: did the Julia team
wrote Python benchmarks the best way for Python? My take on this kind of cross
language ... Note that Julia also can memoize functions, see this example
provided by Ismael V.C.. This automated cache isn't available with ...

IBM ILOG:IBM ILOG Optimization:Mathematical Programming ...

The only example of callback function for CPLEX python API is as follows: .... This
has a much simpler example for a lazy constraint callback. .... You cannot do
anything about 1 (dynamic search is just not compatible with control callbacks)
but you can switch back to multi-threading by explicit setting the ...

Web development tips: Use for threaded Python ...

Aug 21, 2007 ... Databases are happy to handle many parallel requests (doing so is almost in the
definition of a database). However, active processes (threaded or forked) almost
inevitably eat up a valuable resource: database connections. The
module in Martin Blais' 'antiorm' library does a nice job of making ...

IBM ILOG:IBM ILOG Optimization:Mathematical Programming ...

My basic problem is actually that according to my task manager only one core (25
% on a quadcore by the thread javaw) is used. As it stayed constant during
runtime I thought CPLEX is not using all cores. Now, I set 4 cores and the
programm aknowledges that it uses four but the 25% still remain so there ...

Using Net-SNMP and IPython

Dec 11, 2007 ... In this article, learn how to use Net-SNMP, Python, and the IPython shell to
interactively explore and manage a network. ... One example situation is that you
just converted a high-speed DDR into a 2 TB RAID 0 server running Ubuntu
Linux, because that is all you had time to do in the one hour you were ...

Charming Python: Multiple dispatch

Mar 20, 2003 ... Most programmers -- in Python or other object-oriented programming languages
-- who use polymorphism, do so in a rather practical and concrete way. Perhaps
the most common application of polymorphism is in creating a family of objects
that follow a common protocol. In Python, this usually is simply a ...
