CosmoSIS Integration Modules
CosmoSIS Integration Modules Author Marc Paterno Published February 8, 2023 Introduction to integration modules An integration module calculates one or more (typically many) related integrals. They are related in that they are defined by a single integrand: a function of \(n\) variables to be integrated. This function is specified by a user-d...

Data Overview
Data Overview Author Marc Paterno Introduction This document provides a short overview of the ICARUS workflow data we have collected on the csresearch machines at FNAL. This is only to allow us to determine that we are collecting the right data. This is not the data for an interesting performance study. To process this document, you need to h...

Preliminary HEPnOS performance analysis
Updates This document has been updated to include two runs of the eventselection program over the same data. Read the dataframes Run 1 used 112 nodes for the eventselection program, and 16 nodes running HEPnOS daemon processes. We had 32 targets on each HEPnOS node, for a total of 512 targets. It used 63 ranks per node for the eventselection pro...

Comparing VEGAS and CUHRE
Purpose of this document This document shows a comparison of the speed of the VEGAS and CUHRE algorithms, as implemented in the CUBA (http://www.feynarts.de/cuba/) library, and wrapped by cubacpp (https://bitbucket.org/mpaterno/cubacpp). The algorithms vegas is the Vegas algorithm of Lepage, as implemented in the CUBA library. This version uses ...

PandAna Performance part 2
1 Introduction This document presents an analysis of the reading performance of PandAna. PandAna uses the Python package h5py (http://h5py.org) to read tabular data stored in HDF5 (https://portal.hdfgroup.org/display/HDF5/HDF5). We have run a sample PandAna application on 4 or 32 Haswell nodes of Cori at NERSC, using the same code and a varying n...

A first look at grid job output
A first look at grid job output Marc Paterno 2020-08-11 Introduction Yuanyuan has run several grid jobs using the Spack build of CosmoSIS from CVMFS. This document contains some preliminary analysis of the output. She ran using several samplers: emcee, multinest, metropolis and snake. I have run a single job, using the “metropolis” sampler. ...

Parallel CUHRE subregions
Purpose of this document This document analyses the subregions generated by the parallel CUHRE algorithm. The integrand chosen is: \[ | \cos(4 v +5 w + 6 x +7 y + 8 z)/k |\] with \(k = 0s .6371054\). For this integrand, the normalization is approximate (meaning that the true value of the integrand is close to, but not exactly, 1.0). The data rec...

Where CUHRE evaluates functions
Purpose of this document This document shows where the CUHRE algorithm evaluates the function it is integrating. Unlike a Monte Carlo algorithm (such as VEGAS), CUHRE evaluates the function at a set of determinalistically chosen points. The function used as the integrand in this example is: \[ 2 x^2 + 2 y - y^2.\] We have used both VEGAS and CUHR...

Genz function 1 in 8d
Purpose of this document This document shows a performance comparison between the serial and parallel implementations of the CUHRE algorithm for a non-positive-definite integrand. The integrand chosen is: \[ \cos(s + 2 t + 3 u +4 w +5 w + 6 x +7 y + 8 z) / k\] with \[ k = (1/315) \sin(1) \sin(3/2) \sin(2) \sin(5/2) \sin(3) \sin(7/2) \si...
