SUMMARY:(PP25) In Situ Visualization of Laser-Plasma Interaction
DESCRIPTION:Project Poster\n\n(PP25) In Situ Visualization of Laser-Plasma
  Interaction\n\nValenta, Danielová, Klimo, Bulanov\n\nThorough understandi
 ng of ultra-intense laser-plasma interaction may enable new routes in fund
 amental research as well as a wide range of applications. However, such sy
 stems involve collective behavior of particles in self-consistent electrom
 agnetic fields which is, in general, complex and strongly non-linear probl
 em that can be investigated only with the help of numerical simulation.\n\
 nAn exponential increase of computational throughput of supercomputers ena
 bles researchers to perform simulations with unprecedented accuracy. Using
  the conventional post-processing approach of data analysis, such simulati
 ons would require extremely large amount of data to be stored on a persist
 ent storage. The storage bandwidth performance, however, has not grown up 
 as rapidly as the computational power. In practice, the data coming from t
 he simulations have to be stored only at several time-steps or at much coa
 rser resolution than the original data, the rest is just discarded. Theref
 ore, a significant part of information may be potentially lost.\n\nThe tec
 hnique where the simulation data are concurrently analyzed and visualized 
 while it is being generated is usually referred to as in situ processing. 
 In situ processing could circumvent the bottleneck of data transfer. By co
 upling the visualization and simulation together, one may process and anal
 yze the simulation data at high spatial and temporal resolutions without t
 he necessity of involving the storage resources.\n\nRecently, we have inst
 rumented the code EPOCH with the ParaView Catalyst. EPOCH is massively par
 allel, multi-dimensional plasma physics simulation code based on the parti
 cle-in-cell method. ParaView Catalyst is a library that has been designed 
 for in situ coupling of numerical codes with the state-of-the-art visualiz
 ation system. Here we present our implementation strategy, performance ana
 lyses and demonstrate the in situ capabilities on several large-scale lase
 r-plasma simulations.\n\nPasses: Conference Pass, Exhibition Pass, Visuali
