hpchkclm Synopsis hpchkclm [-y] [-n] Description The hpchkclm utility is a command-line tool that checks for the Cell Local Memory mode on HP Integrity server platforms. On mid-range and high end systems, the available system memory can be accessed using two different methods: Interleaved memory The average memory latency is constant for all processes in the system. Non-interleaved memory Provides lower memory latency for processes running in the same cell as the memory. For each cell, it is possible to determine the amount of memory that must not be interleaved. The non-interleaved memory is known as cell local memory (CLM) or global non-interleaved (GNI) memory. The amount of cell local memory can directly affect the system overall performance. Running Windows, better performance can be obtained with maximum CLM. Options -y Eliminates the press any key prompt for automation purposes. -n Suppress the event logging feature.
