Explanation:
A Canadian Natural Science and Engineering Research Council (NSERC) Discovery Subatomic Projects grant was just renewed for a 2-year period to support IceCube and IceCube-Gen2 activities at the University of Alberta and SNOLAB. The level of support is for 4 full-participant faculty (Clark, Grant, Kopper, Moore) and 2 associate faculty (Krauss, Pinfold). Also supported are Juan Pablo, Chris and Joshua with plans for 2 additional PDFs, up to 4 PhD students (in this time) and 4 undergraduate students at the University of Alberta.
Description of service work and planned analysis:
The Alberta group is focused on analyses involving data from DeepCore, the development of the PINGU and high-energy IceCube-Gen2 project and precision studies of astrophysical flux properties such as the flavour composition. Tania’s PhD thesis is the measurement of the atmospheric neutrino flux at energies to ~10 GeV with DeepCore. Sarah is currently working on a “direct reconstruction” tool development running photon propagation on the fly to build a reconstruction hypothesis and will complete her PhD thesis on a test of maximal theta_atm mixing with the 5-year DeepCore dataset. Sebastian will conclude his absolute DOM efficiency with cosmic muons and will then move to his PhD topic of beyond-the-standard-model searches. Sourav is working as part of the Grid Operations Team instructed by the Madison grid group and is working on creating simulation tools allowing the detailed study of very high-energy showers in IceCube simulated with Geant4 well above its original energy limit. He will then move to his PhD topic of identification of hadronic cascades using a delayed signal from neutron capture and applications in neutrino flavor fits. The undergraduates this summer have worked on topics like trigger efficiency studies of PINGU and a direct fitter with simulation.
Computing Resources
Compute-Canada resources have been established as a primary simulation production resource for the IceCube collaboration. In 2017, a resource allocation of nearly 1700 CPU-years and 40 GPU-years from Compute-Canada was awarded to support IceCube activities. Claudio is in the process of constructing a high-performance GPU computing cluster based on TITAN X(p) GPUs with the first 96 GPUs online at this time and a total of 144 GPUs total online by late October 2017. Our service activities are centred on the simulation production and reconstruction developments with these resources, and calibration efforts.
GPU types:
* 14 GPU-years on Tesla K20m [Compute Canada]
* 22 GPU-years on Tesla M2070 [Compute Canada]
* 144 GPU-years on TITAN X(p) [Claudio Kopper]
