The kernel parameters include: default_hugepagesz=1G hugepagesz=1G hugepages=25 hugepagesz=2M hugepages=1024 No mount point is specified for the huge pages as secondary process support is not required. The o/s reports: $ cat /proc/meminfo | grep HugePages_Total HugePages_Total: 25 $ cat /proc/meminfo | grep Hugepagesize Hugepagesize: 1048576 kB Why does it not report the 2M pages? When our application runs I see: EAL: 1024 hugepages of size 2097152 reserved, but no mounted hugetlbfs found for that size Is that an error condition? Best regards David
