ALPS2.0:Parameter

This wiki page is for brainstorming on requirements and specifications for new parameter classes in ALPS 2.0

  • arbitrarily nesting
  • multiple repeated section names
  • DMRG example (from Ian) 
L = x
W = x
Sweep {
States = 50
CalculateObservables = no
}
Sweep {
States = 100
CalculateObservables = yes
}
  • a way to specify 10 sweeps, increasing the States variable linearly from 100 to 1000
  • notation to repeat a section N times (less important?)
  • specification of parameter ranges; each value within that range becomes a task. Currently, this can be done using a trival workarround 
 L=10
 PARAMETERRANGE T 1 1.6 0.2

becomes 

  L=10
  {T=1}
  {T=1.2}
  {T=1.4}
  {T=1.6}
  • A way to have comments in a parameter file that survive in the xml files... and end up in the output xml files?
