COCO - CAPE-OPEN to CAPE-OPEN simulation environment

64-bit vs 32-bit

If you install COCO on a computer with a 32-bit operating system, only the 32-bit version of COCO will be installed. On computers with a 64-bit operating system, several components of COCO will be installed both as 32-bit and as 64-bit versions. The 64-bit versions all have 64 in their name.

On 64-bit operating systems, COFE64 can run more efficiently than COFE (the 32-bit version). However, if your simulation depends on external CAPE-OPEN components that are only available as 32-bit version, COFE64 cannot load these in the most efficient manner (these have to be loaded outside of the COFE64 process, and the GOOOP32 utility application is used for this; Get Object Out Of Process 32). Using out-of-process software components comes with a performance overhead. It may be more efficient (even though COFE itself runs slower) to use the 32-bit version of COFE in this case. COFE64 warns in the log panel in case 32-bit objects are loaded in this manner.
