Win10 Scheduler Bug is confirmed to affect Ryzen# Hardware - 计算机硬件
m*o
1
我在前一个公司有approved eb2 140, PD 是12/05/2008.现在在新公司,PERM刚批下
来,开始办140.律师说有一个策略就是该办eb3,因为eb3快很多。但是比较犹豫的是我
的eb2排期也快了,办eb3会不会因为我办过eb2而被据呢?而且万一eb3排期大倒退也是
个问题。
律师说如果被拒,还可以重新调整去办eb2,但是不知道申请过eb3会不会影响eb2的申请。
有没有大拿给分析一下?
多谢多谢!

"Windows 10′ scheduler correctly identifies Intel’s hyper-threads as
lesser performing than principal core threads and schedules tasks in a way
that’s takes advantage of the additional throughput without negatively
impacting performance. Unfortunately the scheduler currently is not able to
differentiate principal core threads from virtual SMT threads with Ryzen and
in fact sees 16 thread Ryzen 7 processors as processors with 16 physical
cores with equal resources per thread.
Because it does not give any preferential prioritization of scheduling tasks
to primary threads over SMT threads like it does on Intel platforms, a
massively larger percentage of tasks can and do end up getting scheduled for
a virtual SMT thread rather than a principal core thread. Resulting in
significant artificial performance degradation."
...
"If you’re on Windows 10 there are still things you can do to bypass the
scheduler issue and improve performance in specific workloads. For games you
can disable SMT and in most cases see an improvement in performance. This
in fact explains some of the performance disparities we’ve seen in some
games with SMT. If a lot of your work involves lightly threaded or a mix of
single and lightly threaded workloads we’d recommend disabling SMT until
Microsoft releases an update to address the issue. If you’re rendering or
doing some other heavy multi-threaded work you should keep SMT enabled as
this scheduler issue should not affect performance in this scenario to any
significant degree."

如果你PERM已经批下来了,那么其实EB2还是EB3已经定了。如果想换只能整套重新做。

请。

你的PERM决定了这个职位的要求。如果要求了Master学位以上或者本科+5年经验以上就
是EB2,否则是EB3。如果你办PERM时按照EB2要求去测试就业市场,刷美国人,现在却
要按较低要求的EB3办I-140,这从法理上是说不通的。

你的律师说错了。除非他手上有现成的已经在打的广告,而且可以套用到你身上,那你
可以直接PERM。没可能直接改140

Not a shame to know more. I post youtube this time.
This guy made a summary on how to fully take advantage of Zen:
1) Windows bug need to be fixed;
2) Software need to be written as NUMA aware.

你这个PD,安安心心EB2,符合广告条件的人还少一点。等140 relink上,也就直接485
了。别折腾EB3了。
折腾EB3都是09/10的PD

这个说法,好像有些误导。PERM的目的是证明找不到合格的美国人做这个工作,而不是
证明你qualify不qualify。EB3职位如果有更多美国人应征,可能会更难。

Fragomen的律师一般不会错,但是paralegal有比较糊涂的。请你一定要问律师而不是
paralegal。你最好多问律师几遍。

确实是fragomen的律师。他的回复是
If I change to eb3, do I need redo the PERM since my PERM is for eb2
No, we will make the argument in the I-140 filing that since you qualify for
EB-2, you also qualify for EB-3.

你这个排期,EB2拿到卡的时间应该要早些,就算换了EB3递上了485哪年能拿卡谁知道

真需要重载多线程高性能的话牙膏的性价比没有宣传中的那么弱
其实是双方默契一边互相坑一边坑群众 苏妈卖个挑战3倍价格的乖 牙膏也不能跳出来
说自己常年双重价格 只能忍气吞声黑了就黑了 苏妈亦不穷追免得日后自己的服务器芯
片的margin上不去
比如苏妈抓了个1700大洋的8核牙膏产品宣传为假想敌 其实1700大洋可以买E5 2696 V4
还有找(150瓦 22个核心44个HT线程超过60兆的缓存 不需要特殊的主板/内存) 你看苏
妈会放ryzen和这个的跑分对比不?
