+ Collaboration diagram for The modular simulator:

Description

The modular simulator improves extensibility, adds Monte Carlo capabilities, promotes data locality and communication via interfaces, supports multi-stepping integrators, and paves the way for some task parallelism.

For more information, see page_modularsimulator

Enumeration Type Documentation

The operations on CheckpointData.

This enum defines the two modes of operation on CheckpointData objects, reading and writing. This allows to template all access functions, which in turn enables clients to write a single function for read and write access, eliminating the risk of having read and write functions getting out of sync.

enum gmx::IntegrationStage
strong

The different integration types we know about.

Enumerator
PositionsOnly 

Moves the position vector by the given time step.

VelocitiesOnly 

Moves the velocity vector by the given time step.

LeapFrog 

Manual fusion of the previous two propagators.

VelocityVerletPositionsAndVelocities 

Manual position (full dt) and velocity (half dt) fusion.

ScaleVelocities 

Only scale velocities, don't propagate.

ScalePositions 

Only scale positions, don't propagate.

Count 

The number of enum entries.

Sets the number of different position scaling values.

Enumerator
None 

No position scaling (either this step or ever)

Single 

Single scaling value (either one group or all values =1)

Multiple 

Multiple scaling values, need to use T-group indices.

Count 

The number of enum entries.

Sets the number of different velocity scaling values.

Enumerator
None 

No velocity scaling (either this step or ever)

Single 

Single T-scaling value (either one group or all values =1)

Multiple 

Multiple T-scaling values, need to use T-group indices.

Sets the type of Parrinello-Rahman pressure scaling.

Enumerator
No 

Do not apply velocity scaling (not a PR-coupling run or step)

Diagonal 

Apply velocity scaling using a diagonal matrix.

Full 

Apply velocity scaling using a full matrix.
