Reducing wf length from 59400 to 8000,

  • wf/wf outer product is 36.6x faster
  • vls/wf outer product is 5.5x faster

mona should test:

  • the "sparse" outer product from fex
  • full 8000x8000 (plus 8000x2048 for fzp):
    • we can do 8000 samples from 2 hsd channels per drp node at 100kHz (3.2GB/s) from a data-volume perspective but need to check from a CPU perspective.

the full-matrix memory usage with mpi: looks like 8GB for 60 cores for 8000 samples

Estimates of memory usage based on data types (float64, float32, and int16) of the variables:

Code Block
languagebash
>>> b,vls,hsd=(8,2048,8000)
>>> ((vls*b*2)+(hsd*b*2)+(vls*hsd*b)+(hsd*hsd*b))/1e9
0.643232768
>>> b,vls,hsd=(4,2048,8000)
>>> ((vls*b*2)+(hsd*b*2)+(vls*hsd*b)+(hsd*hsd*b))/1e9
0.321616384
>>> b,vls,hsd=(2,2048,8000)
>>> ((vls*b*2)+(hsd*b*2)+(vls*hsd*b)+(hsd*hsd*b))/1e9

in future with 1MHz hopefully have a better detector for fzp that also runs at 1MHz
