      This is known issue on large memory linux machines. To workaround the issue ANSYS development has prepared a small patch to apply to existing installation which will allow the -cflush flag to invoke a separate process, before fluent execution. This will be default mechanism for future releases, but can be applied as a patch on 17.x installations. KEYWORDS: Parallel, Performance, cache, flushing
