We are making available a snapshot release of Trimaran (v.3.7) that includes more accurate tracking of the memory system performance. This release is being made available due to popular demand.

There are various other features that were added (and bugs fixes) but not documented here. This release does pass our regression test suite and is fairly stable. Please report any problems directly to the support team. A new Trimaran distribution will also be made available soon which will include support for clustered architectures.

Note that as with all memory simulations, there are various details that are hard to simulate and you should understand the simulation infrastructure before reporting numbers for publications when memory simulation is enabled. The current distribution also includes the cache simulation interface from SimpleScalar for those who wish to use it (this interface is activated via a compile time flag in the trimaran/simu/src/emulib/Makefile).

This snapshot release also includes more statistics tracking and a new format of the simulator output files. Note however that this new output is not compatible with the GUI visualization tools.
