How many steps?

How many walkers?

• At least double the dimensions.
• I recommend a multiple of the threads you are using to minimise idle-core time.
• I like to scale them as an exponential of ndim.
• You can never go wrong with more
• More walkers means more concurrent memory usage.

How many temperatures?

• Really problem dependant.
• At least 5, more than 20 seems overkill.
