To generate inputs, chess positions are required in the file positions.epd. All the existing positions in that file are from Arasan Testsuite.
To then generate a random workload, run
./gen-input.py [options]
Where the required arguments are:
--count <number>
The number of board positions to inlude
--depth <min> <max>
The minimum and maxium search depths
And the optional parameters are:
--name <workloadName>
Which will be the workloads name. If not given, the name will be the lowest number from 000 to 999 not already existing
--seed <seed>
The seed to feed the random number generator before creating the workload.
