The same test completed on the same hardware in 1m53s with normal 8K pages. The test allocates a total of 48G of RAM and I forced it to use hugepages with 'hugectl --heap=8M'. I passed hugepages=8192 as kernel boot param to make sure all 48G could be allocated with hugepages. Since 8M seems not quite functional, I can work on getting back 4M pages with hopefully decent performance. This would temporarily break THP on sparc/linux but it would allow me to split the work in phases. == For reference, following are logs dumped out during CPU lockup == NMI watchdog: BUG: soft lockup - CPU#40 stuck for 65s!
