Speos HPC Parameters (Command Lines)

Speos HPC provides you with the following parameters (command lines) to configure the simulation check or run:

Command Line

Description

-h

Displays the Speos HPC help.

-v

Displays the Speos HPC version.

-speos speospath

Specifies the path to the .speos file to use for the simulation.

Note: .speos file replace the previous .sv5 file extension. However you can use .sv5 files with the -speos command line.

-file "input file name"

Specifies the name of the input file to use for the simulation.

-check

Runs in check mode: load the .speos and init the simulation (useful to check data and RAM usage)

-gpu

Notifies the cluster to run the simulations job using the GPU instead of the CPU.

Note: When using the -gpu command line, the -threads command line is not needed.

-threads nn

Specifies the number of threads per node (limited by the license and available cores).

-nbrays nnnn

Specifies the number of rays/passes for the Monte Carlo Direct or Inverse simulations.

-disablefiles

Disables all .lpf, .lp3, .ray, .tm25ray output files.

-stime nnnn

-mtime nnnn

-htime nnnn

-dtime nnnn

Runs the simulation during nnnn seconds/minutes/hours/days (only for Monte Carlo simulation).

You can combine these command lines.

For inverse simulation with multiple sensors, the specified simulation time is for each sensor.

-hsave nnnn

-dsave nnnn

Merges and saves the intermediate results every nnnn hours/days (only for Monte Carlo simulation).

You can combine these command lines.

-nosave

Disables the merge and save of intermediate results.

Using -nosave is not recommended.

-nowarnings

Disables all warnings outputs.

-error-lang

Defines the error message output language:

  • "eng" : (default) English

  • "jpn" : Japanese

-first-sensor "sensor number"

Defines the first sensor to be simulated (only for inverse Monte Carlo multi-sensor simulations).

-last-sensor "sensor number"

Defines the last sensor to be simulated (only for inverse Monte Carlo multi-sensor simulations).

Examples

  • Running Speos HPC with the file.speos: 

         
./SPEOSHPC.x –speos path/file.speos

  • Running Speos HPC with the file.speos for 1 day: 

         
./SPEOSHPC.x –speos path/file.speos –dtime 1

  • Running Speos HPC with the file.speos for 500 passes: 

         
./SPEOSHPC.x –speos path/file.speos –nbrays 500

  • Specifying the CodePage converter name: 

         
./SPEOSHPC.x -speos path/file.speos
