SSE3 and onwards support...

If I do "less /proc/cpuinfo", I get -

model name : Intel Xeon CPU X5365 @ 3.00GHz
stepping : 11
cpu MHz : 3000.111
cache size : 4096 KB
physical id : 0
siblings : 4
core id : 0
cpu cores : 4
fpu : yes
fpu_exception : yes
cpuid level : 10
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm
syscall lm pni monitor ds_cpl est tm2 cx16 xtpr lahf_lm

which means "Intel Xeon CPU X5365" supports SSE till sse2.

How to have SSE3 onwards supports on Linux x86_64 with this processor with ICC as -

$ icpc -V

For more complete information about compiler optimizations, see our Optimization Notice.

Go ahead and use SSE3 if you like. The fact that SSE2 is supported doesn't exclude SSE3 and SSSE3, although the latter tends to handicap those more recent CPUs which accept it.
