March Calendar 2025 Ideas Amy Ogden Why no march=native by default? as you have pointed out, besides producing binaries incompatibility with older cpus, march=native isn't necessarily beneficial. it improves performance in some cases such as numerical computing. but it is not beneficial in many other cases, and is sometimes detrimental.

March Calendar 2025 Ideas Amy Ogden In sqlserver, how do i compare dates? for example: select * from users where registrationdate >= '1 20 2009' (registrationdate is datetime type) thanks. March=foo implies mtune=foo unless you also specify a different mtune. this is one reason why using march is better than just enabling options like mavx without doing anything about tuning. caveat: march=native on a cpu that gcc doesn't specifically recognize will still enable new instruction sets that gcc can detect, but will leave mtune=generic. use a new enough gcc that knows about. Yes, gcc clang march=native detects isa extensions supported by the host system and enables all of them. is also detects what cpu it actually is, and enables mtune=icelake client or mtune=znver4 or whatever which can affect instruction selection choices and for example mprefer vector width=512 on zen 4 vs. 256 on other avx 512 cpus. I am looking for a memory testing algorithm that will help my team verify the design and test during production (bad soldering, cross connected address data lines, mismatched impedances, mirroring.
