Recalling Instructions from Idling Threads to Maximize Resource Utilization
for Simultaneous Multi-Threading (SMT) Processors
Abstract
Simultaneous multi-threading (SMT) has been a very popular design in
improving resource utilization by sharing key datapath components among
multiple independent threads. When critical resources are shared by multiple
threads, effective use of these resources proves to be the most
important factor in fully exploiting the system potential. Allowing any of
the threads to overwhelm these shared resources not only leads to unfair
thread processing but may also result in severely degraded overall
performance. How to prevent idling threads from clogging the critical
resources in the pipeline becomes a must in sustaining desired system
performance. In this paper, we show that, if one can manage to recall
instructions of idling threads from Issue Queue (IQ), a very important
shared resource in the SMT pipeline, the system performance is easily
enhanced by a significant margin, with up to 20% for some benchmark mixes.
An even more noteworthy feature about this technique is that
the ensuing hardware overhead is very insignificant and its effect on clock
timing is also negligible. In addition, this proposed feature can also be
easily coupled with other advanced techniques employed
in other stages of the SMT pipeline for potentially additive benefits.

洛杉矶地区有人要买钢琴吗?
现在我联系的一家琴行出价4700,第一年免费调音,以后每年一次,费用在$100元左右(根
据地点),但是要三个人.
还有两个愿意加入吗?
请联系我个人电邮y******[email protected]

夏天豆制品保鲜妙招
夏日温度高,豆制品比其他季节更容易变质,买回豆制品,一定要尽快吃完。若吃不完
要保存,不妨看看下面的保鲜“高招”:
保存豆腐可以用“盐水法”:将食盐化水煮沸,冷却后,将豆腐全部浸入,再放入
冰箱。豆腐干则要放在冰箱最靠近内壁的位置。豆浆如果直接放冰箱冷藏,可以保存一
夜;但如果采用“密闭法”保存,能放一个星期。具体方法是:1.把豆浆烧开,迅速倒
入能密闭的容器(也先用沸水烫过),不要倒太满,留下1/5的空隙。2.盖上盖子,停留
十几秒钟,再把盖子拧到最紧。3.冷却到室温后,再放进冰箱。
豆浆密封冷藏可保质7天。
最后,夏天用豆制品做凉拌菜一定不要忘了放大蒜和醋,因为这两种调料都有杀菌
的作用。凉拌菜最好不要剩。如果剩下了,下顿再吃的时候就要彻底加热,比如可以加
些辣椒、芹菜等新鲜蔬菜一起炒制。

准备从芝加哥搬去加州了,栗子要跟我们坐飞机。在United网站上查了一下Traveling
with In-Cabin Pet,感觉好像就是交125块钱,别的没什么特别要求了,是这样吗?需
要提前跟United打招呼吗?有什么需要注意的呢?
还有就是过安检的时候,不会要求让他过那个扫行李的X-ray吧?
