Hi @xiaokang I tried to find a similar VM on Cascade Lake 8255C CPU @ 2.50GHz running with CentOS 6.8 with kernel below: `Linux VM-32-11-centos 2.6.32-642.6.2.el6.x86_64 #1 SMP Wed Oct 26 06:52:09 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux ` And it report cpuinfo: ``` # cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 85 model name : Intel(R) Xeon(R) Platinum 8255C CPU @ 2.50GHz stepping : 5 microcode : 1 cpu MHz : 2494.142 cache size : 36608 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss syscall nx pdpe1gb rdtscp lm constant_tsc up rep_good unfair_spinlock pni pclmulqdq ssse3 fma cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand hypervisor lahf_lm abm 3dnowprefetch arat xsaveopt fsgsbase bmi1 hle avx2 smep bmi2 erms invpcid rtm avx512f rdseed adx avx512cd bogomips : 4988.28 clflush size : 64 cache_alignment : 64 address sizes : 46 bits physical, 48 bits virtual ``` It can report AVX512 flag correctly. And bitshuffle native code can run correctly. It seems your kernel `ylcs-5 2.6.32-431.el6.x86_64` is very special which I could not reproduce right now. Could you provide the `dmesg` when the issue happen on your system ? -- This is an automated message from the Apache Git Service.
