What is the primary use of the dqmc-advanced skill?

It is designed for researchers using the dqmc toolkit to perform advanced simulations like dynamical correlation measurements, analytic continuation, and large-scale queue management.

What role does MaxEnt play in this skill?

The skill provides implementation patterns for Maximum Entropy (MaxEnt) algorithms to perform analytic continuation, solving for real-frequency spectral functions based on binned imaginary-time data.

How does the dqmc queue system avoid lock contention?

The system utilizes a sharded queue with 128 shards and employs atomic rename operations to claim tasks, preventing performance bottlenecks on distributed filesystems.

How do I enable unequal-time measurements?

You can enable these by setting the 'period_uneqlt' parameter to a value greater than 0 during the file generation phase using 'dqmc-util gen'.
