Welcome!


Thanks for coming to NeSC
Second (or third) Grid Performance
Workshop


Last year at UCL, overview of current tools
This year
Focus on application performance, broadly
defined
 How fast things are running, how fast
should they be running, detection of
performance faults

eSI Event Theme Program

An eScience Institute Event Theme


Series of related workshops, talks, reports
eScience Performance and Information
Services for Smart Decision Making

What is Grid performance, how is it used
today, where should it go tomorrow

Goals for this year



Tool builders to better understand
application needs
Applications to better understand what
tools are available, pros and cons
Try to extrapolate from three strong
examples what other users might want,
what tools should be built, other uses for
the current tools, and information about
scalability
What we asked the
application scientists to tell us



What are the performance criteria that are
most important to you/your users?
How are the hardware resources/services
monitored? (ie. how do you know if the
resources are up?)
How do you detect and manage failures?
(eg. how do you manage file transfer
failures or lost jobs)
Applications 2

What support tools do you use to manage
the performance of your application:




What off-the-shelf tools are you using?
What tools have been developed specifically
for your application?
What other hacks do you use to
monitor/manage performance?
If you could request a new performance
managing tool what would it do?
What we’d like to
see come out of this

A better dialogue between groups
A better understanding of current needs
and development

An influence on the funding bodies

can we write a report telling them what we
think needs to be funded, where the
missing gaps are
 to be followed up in short order with several
proposals addressing exactly those areas of
work

