Contribution to ADASS XV: Parallel Applications with Condor
Perhaps as you read this, Angel will be giving a talk at
ADASS XV on the use
of Condor for non-embarrassingly parallel applications (i.e.
not
made of independent tasks). The chosen sample application was a Radiative Transfer code. The original
code was written with MPI by Nayra Rodríguez Eugenio (based on a sequential
code written by Dr. Corrado Giammanco), and was translated to Condor-MW as
an illustrative example for the talk, allowing much larger problem sizes than
it would be possible with our
Beowulf cluster. If you want more details,
please get in touch.
IntelC/C++ compiler and teTeX-3.0
A couple of weeks ago we upgraded the
teTeX distribution
(which includes TeX, LaTeX, pdfTeX, dvips etc.) to v3.0. Please note that the "psfig" package
has been replaced by "epsfig", so in your latex file change \usepackage{psfig}
with \usepackage{epsfig} (for further details see
teTeX3.0
and psfig). Also, we installed the
Intel
C/C++ Compiler v 9.0.21. Unfortunately, we could not upgrade
the
Intel F90
compiler to v9.0.21 because of odd problems with the spanish localization
and the GNU linker (we opened a ticket with Intel Support).
Parallel Computing Workgroup
In September we organized a course on Parallel Computing which was
quite
well received. But apparently some people wanted more, so we have decided to start
a Parallel Computing Workgroup as an experiment ... The idea is to create a
group of people that are interested in learning Parallel Computing (so far with
MPI), and learn together by discussing and solving on-line exercises in a sort
of Virtual Class. We have no idea whether this will work out, but if you want
to try it, get in touch with us.
Power tools for the budding programmer: Makefiles, Version
Control, Debugger and Profiler
When writing code, do you ever spend a lot of time writing printf commands
to find a bug? or trying to manually revert to the version you had yesterday?
or wondering why your code gave a "Segmentation Fault"? If so,
you should learn how to use the tools mentioned above. If enough people are
interested, we will organize a talk about this. To show your interest, vote
at the
forum.
A quick stroll through the SIE website
Have you visited our website? The
SIE
home page contains a navigation menu, our most recent news and activities
(upcoming
Courses and
Talks, software
installations and upgrades), the most recent
Forum topics,
and links to someFAQs and other (we hope) useful documents. If you wish to know
what software packages we install, maintain and support, go to the
SIE software
list.
Or are you perhaps looking for
Supercomputing
at the IAC? And do not forget to read the interesting discussions in the
SIE
Users Committee. If you can't find what you're looking for, use the new search
box.
