NEC SX-8 and SX-9 Usage and Programming
|
Overview on NEC SX-8 and SX-9 at HLRS, usage, vectorization, parallelization and performance optimization |
|
Filesystems and I/O on NEC SX, BLIS, a vectorized, linear iterative solver,
and optimization hints based on experience in the Teraflop Workbench |
|
Abstract |
Ziel des Kurses ist es, den Teilnehmern die Möglichkeiten der
neuen NEC SX-9 Installation am HLRS aufzuzeigen,
und Ihnen das Rüstzeug zu geben, Cluster aus Shared Memory Vektor
Rechnern in effizienter Art und Weise zu nutzen. Die Konfiguration
der Installation wird ebenso abgedeckt wie Grundzüge der Vektorisierung.
Für erfahrene Vektorrechner Nutzer sind die SX spezifischen Methoden
zur Performance Messung und Analyse, sowie die Bedienung der Compiler
und des Systems insbesondere für parallele Programme von Interesse.
I/O und Optimierung von Anwendungsprogrammen auf der SX-9 runden
das Thema ab.
Ein Schwerpunkt am ersten Nachmittag sind die Unterschiede
zwischen dem Vorgängersystem NEC SX-8 und der neuen NEC SX-9.
The participants learn about the configuration of the
NEC SX-9 system at HLRS and how to use this cluster of
vectorizing shared memory nodes. One focus is
an introduction in vectorization. More experienced users
can learn how to optimize programs based on performance
measurements. Additional topics are I/O and the
optimization of application programs.
The first afternoon is focused on the differences between
the predecessor system and the new NEC SX-9.
Seperate registration of individual days is possible.

Cancelation policy |
If you cannot come to the course, please
send an email to the organizer as soon as possible.
This would allow us to accept additional participants
from the waiting-list. There is no cancelation fee.
NO-SHOW:
Registered persons that do not cancel or do not show up without any
reasons are blocked for the next year on any of our workshops
(because it is to expensive to produce unused copies of the slides
for them).
|
Limit |
maximum of
42 participants in Stuttgart and Kassel,
35 in Dresden and Manno,
34 in Garching,
26 in Jülich,
20 an der TUHH
(according to the seats in the rooms). |
Handouts |
Each participant will get a paper copy of all slides.
The MPI-1 part of the course is based on the MPI course developed by the
EPCC
Training and Education Centre,
Edinburgh Parallel Computing Centre.
If you want, you may also buy copies of the standards
MPI-2.1 (Hardcover, 17 Euro) and OpenMP 3.0 (about 8 Euro).
Most material of the course (including the audio information)
can also be viewed in the
ONLINE Parallel Programming Workshop.
