  Simula-on  run  late  2011,  taking  ~1.5  million  compu-ng  hours,  on  Juropa  at  the  Jülich  Supercompu-ng  Centre  (JSC),  Germany.  Using  8000  cores.  

  6  Gpc/h  box  size,  60003  par-cles  (216  Billion),  Par-cle  Mass:  7.49x1010  /h    Msun,  resolu-on  down  to  the  smoothing  length  of  50kpc/h  

  30  output  slices  stored  of  par-cle  data  (halo  catalogues  stored  for  105  slices)  –  totaling  ~150  TB  of  data

Where?  

21  

  Need  a  large  volume  to  observe  the  effect  as  it  occurs  most  strongly  for  large-­‐scale  perturba-on  modes  in  the  density  field  (100s  of  Mpcs)  

  For  Jubilee  we  need  to  resolve  down  to  the  scale  of  Luminous  Red  Galaxies  (LRGs)  (1013  M  halos)  to  cross  correlate  with  the  ISW  signal  

  Need  many  snapshots  to  ensure  integral  is  accurate  (Jubilee  has  30  between  z  =  0  and  6).

Poten-al  Calcula-on  

22  

  We  calculate  the  poten-al  from  the  density:  

-  Smooth  the  density  field  (CIC,  60003  grid)  -  Calculate  the  poten-al  from  the  density  using  Poisson’s  

equa-on:  

-  And  the  Mul-ple  Fourier  Transform  (MFT)  method  (Hockney  and  Eastwood)  

  From  the  poten-al  we  then  calculate  the  Temperature:

  Complete  remaining  poten-als  from  par-cle  data  (half  done  –  each  par-cle  snapshot  is  5  Tb)    

  Produce  full  sky  maps  of  density  and  poten-al  fields  (not  vital  –  nice  to  have)  

  Convert  poten-al  into  ISW  Temperature  maps  

  Produce  full  sky  maps  of  LRGs  from  halo  catalogues
