SALSA

Scalable Adaptive Large Structures Analysis

Martin Vala

* Simple analysis example (Study of phi meson) * N dimensional histogram - Why it is needed. - What are possible problems? * New ideas how to improve current situation * Possible fast merging via hypercube algorithm * SALSA network ideas * SALSA demo

* 1D histogram with 1000 bins (1000 = ~kB) * 2D histogram with 1000 bins (1000 x 1000 = ~MB) * 3D histogram with 1000 bins (1000 x 1000 x 1000 = ~GB) * ... * N dimensional histogram might be VERY big object

Histogram merging via hypercube algorithm

* Efficient query of N dimensional histogram * Dynamicly change histogram binning (resolution) * Work with histograms that doesn't fit in to memory * Easy to use via laptop or cluster * Easy to use interface (web application)

Multi cluster setup

Simple cluster setup using ipc://

Simple cluster setup using inproc://

Small cluster in my laptop for testing (all threads)

SALSA web interface demo (mockup)

SALSA - Dynamic 2D histogram

* Currently implemented: - Monitor SALSA network nodes/clusters - EOS browser for file browsing - ROOT browser available * Comming soon - SALSA network display - Open ROOT files via EOS browser - Send jobs to SALSA network

Working ...

* nodejs * reactjs * LDAP auth * highcharts * jsroot * EOS API * and ...

in slovak that means DONE.

SALSA web interface (release is comming)

We would like to thank you
