In order to run a native program on the Intel® Xeon Phi™ coprocessor, the program and any dependencies must be copied to the target platform. However, this approach takes away memory from the native application. To reserve memory resource (16-GB GDDR5 memory on board the Intel Xeon Phi coprocessor), it is practical to mount a Network File System (NFS) shared directory on the Intel Xeon Phi coprocessor from the host server so that most of its memory can be used for applications.
The Intel® VTune™ Amplifier XE 2017 has a new feature called disk input and output analysis that can be used to analyze disk-related performance issues based on device utilization, latency of requests and bandwidth to the device. This provides a consistent view of the storage subsystem combined with the hardware events like device queue utilization, I/O transfer rate and an easy to use method to match user-level source code with I/O packets executed by hardware.
