2009/2010 including deployment and benchmarking of prototypes for
Petaflops systems and porting, optimising, peta-scaling of applications
Project facts:
– Partners: 16 Legal Entities from 14 countries
– Project duration: January 2008 – December 2009
– Project budget: 20 M € , EC funding: 10 M €
PRACE is funded in part by the EC
under the FP7 Capacities programme
grant agreement INFSO-RI-211528

Tier 1: National level: supercomputer system
at CSC
i) more tightly connected part (more expensive per
CPU)
≈ ’capability’ part
ii) massive cluster part (less expensive per CPU)
≈ ’capacity’ part
Tier 2: (Cross-)departmental clusters at
universities and research institutes
Supercomputer ‘Louhi’: Cray
•
Cray XT4/XT5
– genuine homogeneous massively parallel
processor (MPP) system
– Cray’s proprietary interconnect SeaStar2(+),
very good scalability
•
At all phases
– memory 1 GB/core, but in a subset of cores 2
GB/core (in 384 XT4 and 768 XT5 cores)
– local fast work disk 70 TB (fiber channel)
•
Operating system:
– in login nodes complete Linux (Unicos/lc,
based on SuSE Linux)
– in computational cores Cray Linux
Environment: a light-weight Linux kernel
which requires certain minor modifications
to the source code of programs
Supercomputer ‘Louhi’: Cray
Peak performance 10.5 Tflops -> 86 Tflops
• Phase 1
– In full operation since April 2, 2007
– 11 production cabinets, AMD Opteron 2.6 GHz 2-core,
10.5 Tflops peak performance, 2024 computational cores
• Phase 2
– At 2 stages in summer and fall 2008, 2.3 GHz AMD Opteron 4core
– Upgrading in XT4 the dual-core CPUs to quad-core CPUs, and
bringing in XT5 additional cabinets; single combined system
– The combined XT4/XT5 configuration has been in general
customer usage since October 8, 2008: 86.7 Tflops peak power,
9424 computational cores
Supercluster ‘Murska’: HP
Peak performance 11.3 Tflops
•
•
•
•

•
In full operation since July 12, 2007
2176 processor cores: 2.6 GHz AMD Opteron
2-core
Interconnect: Infiniband (industry standard,
middle-range scalability)
Local fast work disk: 98 TB (SATA)
Memory: in 128 core 8 GB/core (32 GB/node),
in 512 core 4 GB/core, in 512 core 2 GB/core,
in 1024 core 1 GB/core.
HP XC-cluster, operating system is Linux
(based on Red Hat Enterprise Linux
Advanced Server 4.0)
Machine room and hosting provided by HP for
at least the first 2 years
On profiling the systems
• HP supercluster ‘Murska’:
–
–
–
–
–
For a large number of computational customers
No porting of codes needed
Data-intensive computing
Jobs needing more memory
‘Multiserial’ jobs
• Cray XT4/XT5 supercomputer ‘Louhi’:
– For a smaller number of research groups
– For runs/codes which benefit from Cray (in performance/price –
sense)
– Software: only as needed by those groups
– Customers will be helped in porting the codes to Cray
– In batch queue system more towards capability-type profiling:
space for very large parallel jobs => a somewhat
lower usage percentage

a joint project of CSC, 7 Finnish universities
and Helsinki Institute of Physics, funded
partially by the Finnish Academy in the
National Research Infrastructure
Programme
has built a homogeneous PC-cluster
environment with theoretical peak of
approx. 3 Tflop/s (350 nodes)
Environment
