Introduction

We have been working on another approach to speeding dynamics greatly, based on a new technique called Normal Mode Langevin (NML) dynamics. This method uses the same style models as normal MD (same force fields, etc) and thus should have the same accuracy, but with a pretty significant speedup due to algorithmic advances. NML is complementary to our other methods, so we're hoping to add it to everything else (in particular to the GPU core). To start, we will be testing it in a new core, based on the Protomol software. Protomol is designed to allow for rapid prototyping of molecular simulations, which is perfect for NML.

Initial release

Why don't things show up correctly in my Third-party monitoring tool (like FahMon)?

Third-parth monitoring tools are not a officially supported. They relies on some undocumented features of the older cores which are not the same in the new core and will likely not be the same in future cores.

That said, we will work towards an officially supported method of displaying/acquiring core information.

When I run two or more cores on the same machine why do I get this error Exception in thread 0: @ fah\net\Socket.cpp:137:<unknown> 0: Could not bind socket to 127.0.0.1:52753: No error?

This is a non-fatal error that can be safely ignored. The core tries to bind the port 52753 and only one core can do so at one time. The core provides a server that is used by some visualization tools. This may be removed in the future.
