Limitations related to collection of disk usage statistics:
To collect the statistics, Application Performance Snapshot uses data provided by the OS. Wait time or idle time caused by waiting data from the I/O subsystem is measured with relatively low precision. This is why for short tasks I/O wait time may equal zero, even in case the I/O subsystem is actively used.
During a process run, if the system reassigns it to a different CPU core, the data read/written and I/O wait time will equal zero.
Limitations related to MPI support:
mode is not supported.
Application Performance Snapshot is incompatible with the Intel® Trace Collector. Avoid analyzing MPI applications with both tools simultaneously.
Application Performance Snapshot does not fully support neighborhood collective communications. It registers only their execution times, without information about data transmitted and its direction.
