Agenda

Project status

The project plan is being followed:

- PDF form at: https://wiki.neic.no/wiki/EISCAT_3D_Data_Solutions#Documents - The google docs version is at: https://docs.google.com/document/d/1rgO0qtHJR6zjigdQ2KytFD3ySLH11XvasvSpJNCBVGg/

• Project works well... good attendance to meetings

• Deliverable documents are "owned" by the partners. So far has worked well.

• Deliverable 2 (Ari-CSC) being finished...

https://wiki.neic.no/int/E3DDS_Deliverable_2

- At the time of writing this agenda, we are still collecting details.

- The SBF is now proposed to be split between FSRU (t) and RB (phase) nodes. Still to be tested.

- The phase multiplication scaling needs to be tested (Dan). Does not scale well.

- The size of the prompt computing cluster still variable.

- All other sections completed.

FtF Meeting in Umea

• https://wiki.neic.no/int/Face_to_Face_meeting_Umea_May_29th_2019

• A recommendation for a test cluster made.

Data Transfer tests

• See:

Deliverable 3

• Dan - Uninett

• "The simulations (Deliverable 1) running in the NP e-infrastructures are now run as scale simulation of the EISCAT_3D operations."

• Work starts before holidays. Due October 2019.

Cluster Management

• We have not proceeded so far
• Roles of the various computing on-site are not clearly known...

• e.g. Ring buffer nodes
  • house "disk" buffer SSDs
  • perform phase multiplication (FSRU takes care of time)

• prompt computing
  • GPU speed-up negligible.

Data Transfer Tests

• We have acquired resources NDGF and SNIC (until end of June)

• Tests underway.

• See: https://docs.google.com/presentation/d/1n-p5AjmZbriq0t6TXG8o2ReJlU9gkJHAtdI_35tSYt8/

• We actually start to have numbers!
