Omega TK 2.5.2¶
The fragment library is now shared across multiple instances of the OEOmega objects in a thread-safe manner. This can greatly reduce the amount of memory needed to run a multi-threaded version of Omega TK. For example, the memory consumption of Omega TK running across 8-cores dropped from 715MB to 258MB for 14,000 lead-like compounds from MDDR. This can also lead to a performance improvement since expensive fragment generation can sometimes be avoided if it has already been completed by another thread.
