1. Introduction


In 1930, John Vincent Atanasoff has had a problem leading to t he

extremely large-scale system of 30 linear algebraic equati ons arising from

application of Ritz method for discretization of different ial equations.

This has been the motivation to invent the computer.

High Performance Computing (HPC) is one of the most rapidly d eveloping

part of computational sciences.

The advanced HPC applications reach billions of degrees of f reedom.

2. Infrastructure for the production and research of new mat erials

3. Infrastructure for genome, proteome and metabolome resear ches

IICT - BAS is a member of the consortium

4. Infrastructure in the area of renewable energy sources an d energy

efficiency

5. Bulgarian supercomputing centerScientific and technical coordinator: CoE on Supercomputin g applications

(IICT - BAS is a coordinator of SuperCA++)

6. BG-CLARIN: integration and development of Bulgarian langu age electronic

resources as a part of European CLARIN

Scientific and technical coordinator: IICT - BAS

7. Astronomical center for research and education


Approach towards HPC

Concentrate on better management and exploitation of exist ing HPC

Definition of new directions in areas important to ensure the catching up

process

Stepping up collaboration with other countries and interna tional

organisations

Financial Instruments IBM Blue Gene/P

It is attractive speaking about HPC, but keep in mind exponen tial growing

overall expectations

HPC is an enabler of scientific and innovative results not a re ady solution

or result


3. Infrastructure development

IICT-BAS is the main coordinator for e-Infrastructure acti vities in Bulgaria

National Research and Education Network

Bulgarian Grid Infrastructure

Supercomputer Blue Gene/P

Grid and Supercomputing applications

National and international e-Infrastructure projects


About IICT

1985 - Center for Informatics and Computer Technology (CICT )

1995 - Central Laboratory for Parallel Processing (CLPP)

2003 - Institute for Parallel Processing (IPP)

2010 - The Institute of Information and Communication Techn ologies at the

Bulgarian Academy of Sciences - (IICT) is founded as a succes sor of

Institute for Parallel Processing, Institute of Informati on Technologies and

Institute of Computer and Communication Systems


IICT basic scientific trends

IICT-BAS has the leading position in Bulgaria in the field of:

Network and Grid services

Grid, Cloud and GPU computing

Large-Scale scientific computations and supercomputer app lications

Security and information systems

A large number of international projects (total number: 39 f or the last 5

years), among them:

EGEE -1st, 2nd and 3rd phase, EGI-InSPIRE

SEEGRID-1, SEEGRID-2, SEEGRID-SCI, HP-SEE

CoreGRID, GRINKO, PSIRP, FORWARD

Projects funded by Bulgarian National Science Fund (NSF) (3 6 for the last

5 years)


National eI responsibilities

IICT-BAS coordinates consortium of 3 universities and 3 ins titutes of the

Academy in Center of Excellence ”Supercomputer Applications”

(SuperCA++) .

IICT-BAS coordinates the National Grid Initiative (NGI) (named Bulgarian

Grid Consortium) and presents it in the EGI Policy Board.

IICT-BAS hosts the main node of BREN and is a member of the Board of

Bulgarian Research and Educational Network (BREN).

IICT-BAS is responsible for the operations of the Bulgarian Academic

Certification Authority (http://ca.acad.bg/) which is authorized to issue digital

Grid certificates free of charge for all Bulgarian Grid users or hosts.


BREN

The Bulgarian Research and Educational Network (BREN) is th e academic

provider of Internet for Bulgaria.

Members of BREN:

Executive Agency ”Electronic Communication Networks and I nformation

Systems”, Ministry of Transport, Information Technology a nd

Communications

Bulgarian Academy of Sciences

The Council of Bulgarian Universities Rectors

National Research Network


The Bulgarian Grid consortium

Founders: Institute for Parallel Processing (IPP-BAS, former CLPP-BAS)

and Institute for Nuclear Research and Nuclear Energy (INRNE-BAS) (

Agreement signed in September 2002)

Joined by 8 institutes and 4 universities in the next several years

Active work started 2004

Since 2007, IPP-BAS is recognized as the coordinator of Bulg arian Grid

Initiative

Main goals: Sharing of resources and expertise in Grid techn ologies;

Development of Grid applications.

5. Parallel scalability

Figure: 1D, 2D and 3D partitioning: voxel triangulation of a cubic domain

Parallel numerical tests for a parabolic problem in cubic sp ace domain, voxel FEM mesh, and 96implicit backward Euler time steps, are given bellow.

Unstructured meshes

Figure: 3D FEM discretization: unstructured mesh and and Par METIS partitioning for 16 processors

ParMETIS is developed by Karypis Lab. It is an MPI-based para llel library that

implements a variety of algorithms for partitioning unstru ctured graphs,

meshes, and for computing fill-reducing orderings of sparse matrices.

ParMETIS partitioning

Table: 3D FEM discretization: unstructured mesh and and ParM ETIS partitioning for 512 processors

ParMETIS computes in parallel partitionings of very large u nstructured

meshes.

A high quality balance with respect to the number of elements and

vertices, and minimization of the size of interfaces is prov ided.

The relatively large number of neighbors is still an open pro blem.

6. Conclusions

Bulgaria has visible presence and active role in the area of

e-Infrastructures in the SEE region with its achievements, expertise and

resources.

Bulgaria is a pioneer in SEE region in the field of national SC p rograms

(SuperCA, SuperCA++), and IICT-BAS is ready to share its exp erience.
