The papers in this volume were presented at ICLSSC 2001, the Third Inter- tionalConferenceonLarge-ScaleScienti?cComputing. ICLSSC2001washeldin Sozopol,Bulgaria,June6-10,2001. Theconferencewasorganizedandsponsored bytheCentralLaboratoryonParallelProcessingoftheBulgarianAcademyof Sciences,andtheDepartmentofNumericalAnalysisandStatisticsoftheUniv- sityofRouse,Bulgaria. SupportwasalsoreceivedfromtheCenterofExcellence "BIS21"(fundedbytheEuropeanCommission),SIAM(SocietyforIndustrial andAppliedMathematics)anditsActivityGrouponSupercomputing. Weare indebtedtoourcolleagueswhohelpedusintheorganizationofthisconference. Wethanktheorganizersofthespecialsessions:O. Axelsson,I. Dimov,A. Ebel, K. Georgiev, V. Getov, S. Heinrich, O. Iliev, A. Karaivanova, S. Margenov, P. Minev, M. Sch. afer, and Z. Zlatev. We also thank I. Lirkov for the help in puttingtogetherthisbook.

The invited speakers included university and practical engineers from industry, as wellasappliedmathematicians,numericalanalysts,andcomputerexperts. The generalthemeforICLSSC2001wasLarge-ScaleScienti?cComputing,focusing on: - Robustpreconditioningalgorithms, - MonteCarlomethods, - Advancedprogrammingenvironmentsforscienti?ccomputing, - Large-scalecomputationsinairpollutionmodeling, - Large-scalecomputationsformechanicalengineeringproblems,and - Numericalmethodsforincompressible?ow. The workshop itself attracted about 80 participants from around the world. Authors from over 15 countries submitted 52 papers, of which 7 were invited, and 45 were contributed. The Fourth International Conference (ICLSSC 2003) willtakeplacein2003.
