Query methods
For user's application: Copy following code exactly (till the end of this class) and do NOT change anything. The reason can not put following functions in base class `AlpsParameterSet` is: `boolParams` and `endOfBoolParams` etc. can NOT be declared in base class. They are different types for each derived classes. The members of the parameter set can be queried for using the overloaded entry() method. Using the example in the class documentation the user can get a parameter with the "<code>param.entry(USER_par::parameter_name)</code>" expression.
bool | entry (const boolParams key) const
int | entry (const intParams key) const
double | entry (const dblParams key) const
const std::string & | entry (const strParams key) const
const std::vector< std::string > & | entry (const strArrayParams key) const
Packing/unpacking methods
void | pack (AlpsEncoded &buf)
| Pack the parameter set into buf.

## Member Enumeration Documentation

enum AlpsParams::boolParams

Character parameters.

All of these variable are used as booleans (ture = 1, false = 0).

Enumerator:

  checkMemory | Check memory. Default: false
  deleteDeadNode | Remove dead nodes or not. Default: true.
  interClusterBalance | Master balances the workload of hubs: centralized. Default: true.
  intraClusterBalance | Hub balances the workload of workers: receiver initialized. Default: true
  printSolution | Print solution to screen and log if have a solution and msgLevel and logFileLevel permits. Default: false.
  endOfBoolParams |

Definition at line 40 of file AlpsParams.h.

enum AlpsParams::intParams

Integer paramters.

Enumerator:

  bufSpare | The size of extra memory allocated to a message buffer. Default: 256 byte
  clockType | Type of clock when timing rampup, rampdown, etc. CPU or Wallclock. default: wallclock
  eliteSize | Number of the "elite" nodes that are used in determining workload. Default: 1
  hubInitNodeNum | The number of nodes initially generated by each hub. Default: 2
  hubMsgLevel | Message level of the hub specific messages. (0: no print to screen; 1: summary; 2: moderate; 3: verbose) Default: 0
  hubNum | The number of hubs. Default: 1
  largeSize | The size of memory allocated for large size message. Default: 10485760
  logFileLevel | The level of log file. (0: no log file; 1: summary; 2: moderate; 3: verbose) Default: 0
  masterInitNodeNum | The number of nodes initially generated by the master. Default: 2
  masterReportInterval | The interval between master report system status. Default: 10
  hubWorkClusterSizeLimit | If the number of processes in a cluster is less than it, the hub also work as a worker. Default: 0 (Hub does NOT work)
  mediumSize | The size of memory allocated for medium size message. Default: 4096
  msgLevel | The level of printing messages on screen. Used to control master and general messages. (0: no print to screen; 1: summary; 2: moderate; 3: verbose) Default: 2
  nodeLimit | The max number of nodes can be processed. Default: ALPS_INT_MAX
  nodeLogInterval | Node log interval. Default: 100
  printSystemStatus | Print system status: 0: do not print, 1: print. Default: 1;
  processNum | The total number of processes that are launched for parallel code. Default: 2 Not used since can get actual number of processes from MPI.
  staticBalanceScheme | Static load balancing scheme -- root initialization (0) -- spiral (1).
  searchStrategy | Search strategy -- best-first (0) -- best-first-estimate (1) -- breadth-first (2) -- depth-first (3) -- hybrid (4) Default: hybrid.
  searchStrategyRampUp |
  smallSize | The size of memory allocated for small size message. Default: 1024
  solLimit | The max num of solution can be stored in a solution pool. Default: ALPS_INT_MAX
  unitWorkNodes | The size/number of nodes of a unit work. Default: 50
  workerMsgLevel | Message level of the worker specific messages. (0: no print to screen; 1: summary; 2: moderate; 3: verbose) Default: 0
  endOfIntParams |

enum AlpsParams::dblParams

Double parameters.

Enumerator:

  changeWorkThreshold | The threshold of workload below which a worker will change the subtree that is working on. Default: 0.05
  donorThreshold | It is between 1.0 - infty. When the workload in process is more than the average workload timing donorThreshold, it is a donor in load balancing. Defaut: 0.1
  hubReportPeriod | The time period (sec) for hubs to process messages. Default: 0.1
  masterBalancePeriod | The time period for master to do loading balance/termination check. Default: 0.05
  needWorkThreshold | The threshold of workload below which a process will ask for workload Default: 2.
  receiverThreshold | It is between 0.0 - 1.0. When the workload in process is less than the average workload timing receiverThreshold, it is a receiver. Default: 0.1
  timeLimit | The time limit (in seconds) of search. Default: ALPS_DBL_MAX
  tolerance | The numeric tolerance. Default: 1e-6
  unitWorkTime | The time length of a unit work. Default: 0.5
  zeroLoad | If less than this number, it is considered zero workload. Default: 1e-6
