19th VI-HPS Tuning Workshop NLHPC
This workshop organized by second time by VI-HPS, Universidad de La Frontera (UFRO, Temuco, Chile) and NLHPC will give an overview about the VI-HPS programming tools suite, explaining the functionality of individual tools, and how to use them effectively offer hands-on experience and expert assistance using the tools.
Goals
This workshop organized by second time by VI-HPS, the Universidad de La Frontera (UFRO, Temuco, Chile) and the NLHPC will give an overview of the VI-HPS programming tools suite explain the functionality of individual tools, and how to use them effectively offer hands-on experience and expert assistance using the tools
Programme Overview
Presentations and hands-on sessions are planned on the following topics:
Setting up, welcome and introduction
Score-P instrumentation and measurement
Scalasca automated trace analysis
Periscope automated performance analysis
Paraver trace analysis and performance prediction
MAQAO performance analysis & optimization
PAPI hardware performance counters
A brief overview of the capabilities of these and associated tools is provided in the VI-HPS Tools Guide.
The workshop will be held in English and run from 09:00 to not later than 18:00 each day, with breaks for lunch and refreshments. There is no course fee, however, all participants are responsible for their own travel, accommodation and expenses
Classroom capacity is limited, therefore priority will be given to applicants with parallel codes already running on the workshop computer system (Leftraru), and those bringing codes from similar Linux cluster systems to work on. Participants are therefore encouraged to prepare their own MPI, OpenMP and hybrid MPI+OpenMP parallel application codes for analysis.
Participants are expected to use their own notebook computers with SSH/X11 software installed to connect to Leftraru. The tentative schedule is the following
Hardware and Software Platforms
Leftraru: HP SL230/SL250 system:
132 compute nodes each with two Intel Xeon E5-2660v2 ‘Ivy Bridge’ processors (10 cores per processor)
12 Intel Xeon Phi 5110p co-processor cards
network: Infiniband FDR interconnect
software: MPI; GCC and Intel compilers
filesystem: 274TB Lustre
The local HPC system Leftraru is the primary platform for the workshop and will be used for the hands-on exercises. Course accounts will be provided during the workshop to participants without existing accounts. Other systems where up-to-date versions of the tools are installed can also be used when preferred, though support may be limited and participants are expected to already possess user accounts on non-local systems. Regardless of whichever systems they intend to use, participants should be familiar with the relevant procedures for compiling and running their parallel applications (via batch queues where appropriate).
