PE Message Queue Display

TotalView supports the Message Queue Display (MQD) feature when used with the threaded version of the IBM MPI libraries that are part of the IBM Parallel Environment (PE). PE version 2.2 and the non-threaded PE 2.3 and later libraries do not provide TotalView with the necessary information for the MQD feature. However, Automatic Process Acquisition (APA) is supported in PE 2.2 and later. The following table summarizes TotalView's IBM PE support:

IBM PE version	APA Support?	MQD Support
2.2	Yes	No
2.3	Yes	Threaded MPI only
2.4	Yes	Threaded MPI only
3.1	Yes	Threaded MPI only
