Part I: Call for participation in poll.

Do you happen to forget to make time for Haifux?

We currently give only a late notice (reminder), counting on people to 
get updated using other means (website, calendar).

We do not want to burden you with announcements, so we would like to 
know how many announcements you would like to get, and when. Keep in 
mind that things may change at the last minute, so the sooner we 
announce the more we might need to correct announcements. However, 
meetings seldom get rescheduled on the last week.

Please take this poll to voice your opinion. The link to your poll is:


Either way, this list retains its once-in-two-weeks policy unless an 
explicit notice is sent.

Part II: Lecture announcement

On Monday, April 2nd at 18:30, Haifux will gather to hear a talk by 
Razya Ladelsky (IBM HRL):

   Automatic parallelization in GCC

*** Please note the change of room! ***


With the emergence of multicore architectures there is a growing need 
for automatic parallelization, that distributes sequential code into 
multi threaded code. OpenMP defines language extensions to C, C++, and 
Fortran for implementing multi-threaded shared memory applications. 
Generation of such extensions by the compiler relieves programmers from 
the manual parallelization process. OpenMP specification has been 
implemented in GCC, and is part of the standard release since version 4.2.

In this talk we review the OpenMP and the data dependence support which 
serve as the basic infrastructure for the automatic parallelization in 
GCC. We describe the capabilities of the automatic parallelization, 
demonstrated by some examples, and show its benefits with SPEC2006 
experiments. Finally, we discuss current and future directions of work 
that may further extend the optimization's applicability.


We meet in Taub building, room 3. For instructions see:

Attendance is free, and you are all invited!
