I don't have cpuinfo prog as of the moment so I've pasted my VM's cpuinfo file instead. processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 58 model name : Intel(R) Core(TM) i5-3340M CPU @ 2.70GHz stepping : 9 cpu MHz : 2658.957 cache size : 6144 KB fpu : yes fpu_exception : yes cpuid level : 5 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 syscall nx rdtscp lm constant_tsc rep_good nopl pni monitor ssse3 lahf_lm bogomips : 5317.91 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: It seems that there is no avx here, does this mean this doesn't support avx instructions ?
