This presentation discusses Open Parallel's model, the background and

major technology changes that originated it, its first major project

(2010-2011) sponsored by Intel, and explains the invitation for the audience

to be part of this and following projects


Agenda

• Multicore - Parallelism - Open Parallel: Background and Context

• TBB - HipHop

• The Future (what we can do)


The problem


Certain things don't last forever


The options


You can chose to ignore it


You can wait for help


You can discuss in committees


It's better to aim high


Discuss Creative Solutions with all the

members of your Team


Parallelism is out there


But has some problems


And you learned it here: S... Happens!


So before you go for help somewhere else


Let's discuss together, how to deal with it, because there are different options


Multicore“The Trouble with Multicore”

(Chipmakers are busy designing microprocessors that most programmers can't handle)

Prof David Patterson, Berkeley (IEEE Spectrum, July 2010)

An entrepreneur's dream: a big gap in the market!


Parallelism

Peter Denning (ACM) – Jack Dennis (MIT)

The Resurgence of Parallelism

(Communications of ACM – June 2010)


About

Open Parallel Limited

Incorporated in 2010 in NZ, Open Parallel is a company supported by an ecosystem that works around parallel programming independently of the size of the problems.


Background (2005 - 2008)

World45, first multicore software company in NZ - partner with Sun Microsystems

Niagara - NDPS - Otago University: first Sun OpenSparc Centre of Excellence outside US

Multicore Expo Santa Clara


Those were the days!

!!!! We even went to the NBA!!


The Transition 2008 - 2009

• MulticoreNZ - Japan

• Open Source Learning Lab

• LCA2010 - LCA2011 - Multicore and Parallel Computing Miniconf


HipHop - what is it

• PHP to C++ compiler

• developed by Facebook

• not the only one (phc)


why special

• dropped feature of core lang

• tuned towards performance

• no drop in replacement for Zend


why bother?

• reduces resource consumption by 50-70%

• can use threading

• did I mention performance?


WordPress -> HipHop

• patch set (remove eval statements)

• use hphpi for development

• results on github


performance difference 1

• WordPress LAMP stack

• crashed the VM

• clearly we pushed it too hard



• WordPress HipHop stack

• responsive, worked nicely

• did we push it enough?


TBB, what is it?

• open source threading lib

• easy to use

• Intel but runs on other platforms


TBB in HipHop

• already used in memory management

• parallel_for extension

• extended PHP language


TBB in WordPress

• run tasks in parallel

• hacked WordPress to use parallel_for

• compiled on HipHop



• even faster than HipHop

• even less resources than HipHop

• TBB rocks


conclusion

• TBB and HipHop is a good fit

• HipHop can drastically speed up PHP

• HipHop can be hacked to certain needs
