If the parallel engine is installed on a computer that runs Microsoft Windows Server, Standard or Enterprise edition, enable auto-tuning for the system page size. Enabling auto-tuning ensures that sufficient memory is available for page tables and page table entries.
To support virtual to physical address translation, the Windows operating system uses page tables and page table entries (PTEs). These tables reside in kernel memory. If not enough memory is allocated for the page tables, Windows might fail to create processes, threads, and I/O buffers. Because the parallel engine creates many processes to run a job, jobs will fail at startup or during run time if Windows does not have enough resources to create processes.
You can enable auto-tuning at server startup by editing the SystemPages registry value in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management registry subkey.
