Some device-tree properties will be missing on a shared # processor. Hence some sched domains may not make sense for shared processor # systems. # # Most shared processor systems are over-provisioned. Underlying PowerVM # Hypervisor would schedule at a Big Core (SMT8) granularity. The most recent # power processors support two almost independent cores. In a lightly loaded # condition, it helps the overall system performance if we pack to lesser number # of Big Cores. # # Since each thread-group is independent, running threads on both the # thread-groups of a SMT8 core, should have a minimal adverse impact in # non over provisioned scenarios. These changes in this patchset will not # affect in the over provisioned scenario. If there are more threads than # SMT domains, then asym_packing will not kick-in. # # System Configuration # type=Shared mode=Uncapped smt=8 lcpu=96 mem=1066409344 kB cpus=96 ent=64.00 # So 64 Entitled cores/ 96 Virtual processor Scenario # # lscpu # Architecture: ppc64le # Byte Order: Little Endian # CPU(s): 768 # On-line CPU(s) list: 0-767 # Model name: POWER10 (architected), altivec supported # Model: 2.0 (pvr 0080 0200) # Thread(s) per core: 8 # Core(s) per socket: 16 # Socket(s): 6 # Hypervisor vendor: pHyp # Virtualization type: para # L1d cache: 6 MiB (192 instances) # L1i cache: 9 MiB (192 instances) # NUMA node(s): 6 # NUMA node0 CPU(s): 0-7,32-39,80-87,128-135,176-183,224-231,272-279,320-327,368-375,416-423,464-471,512-519,560-567,608-615,656-663,704-711,752-759 # NUMA node1 CPU(s): 8-15,40-47,88-95,136-143,184-191,232-239,280-287,328-335,376-383,424-431,472-479,520-527,568-575,616-623,664-671,712-719,760-767 # NUMA node4 CPU(s): 64-71,112-119,160-167,208-215,256-263,304-311,352-359,400-407,448-455,496-503,544-551,592-599,640-647,688-695,736-743 # NUMA node5 CPU(s): 16-23,48-55,96-103,144-151,192-199,240-247,288-295,336-343,384-391,432-439,480-487,528-535,576-583,624-631,672-679,720-727 # NUMA node6 CPU(s): 72-79,120-127,168-175,216-223,264-271,312-319,360-367,408-415,456-463,504-511,552-559,600-607,648-655,696-703,744-751 # NUMA node7 CPU(s): 24-31,56-63,104-111,152-159,200-207,248-255,296-303,344-351,392-399,440-447,488-495,536-543,584-591,632-639,680-687,728-735 # # ebizzy -t 32 -S 200 (5 iterations) Records per second.
