Enhancements

Thread-Safe ACIS

The ACIS thread-safe infrastructure can now utilize 1024 active threads simultaneously. This is a significant increase to the previous limit of nine. This number, defined as MAX_ACTIVE_THREADS, was chosen to more closely match the capabilities of current operating systems and also to remain stable for the foreseeable future. Application developers must choose an optimal number of threads to utilize in their particular circumstances, a value that in most cases should closely match the number of available processors.

Paging (Model Minimization)

While previously undocumented, the ACIS Paging System had a 2 GB page-file limitation. This limitation has been removed. Now, >2 GB page files are supported on all platforms.
