Caching Getting Data In general, getting data from a service once is better than getting it twice. Consider the example of an MVC web application running in a web role that has already retrieved a 50MB blob from the storage service to serve as content to a user. The application could then retrieve that same blob every time a user requests it, or it could cache it locally to disk and reuse the cached version for subsequent user requests. Furthermore, whenever a user requests the data, the application could issue GET with a conditional header for modification time, which would avoid getting the entire blob if it hasn't been modified.
Background[ edit ] The controversy began on election night, when the national television networks, using information provided to them by the Voter News Servicean organization formed by the Associated Press to help determine the outcome of the election through early result tallies and exit pollingfirst called Florida for Gore in the hour after polls closed in the peninsula but about ten minutes before they closed in the heavily Republican counties of the panhandle in the Central time zone.
Later in the evening, the networks reversed their call, moving to "too close to call", then later giving it to Bush; then they retracted that call as well, finally indicating the state was "too close to call".
The small margin produced an automatic recount under Florida state law, which began the day after the election. That first day's results reduced the margin to just over votes.
The Palm Beach County recount attracted protestors and media. Due to the narrow margin of the original vote count, Florida Election Code It was completed on November 10 in the 66 Florida counties that used vote-counting machines and reduced Bush's lead to votes.
On November 9, the Bush campaign announced they had hired George H.
Following the statewide machine recount, the Gore campaign requested a manual recount in four counties. Florida state law at the time allowed a candidate to request a manual recount by protesting the results of at least three precincts. Volusia County started its recount on November Florida statutes also required that all counties certify and report their returns, including any recounts, by 5: The manual recounts were time-consuming, and it soon became clear that some counties would not complete their recounts before the deadline.
On November 11, it joined a group of Florida voters in suing in federal district court for a preemptive injunction to stop all manual recounting of votes in Florida. Bush's lawyers argued that recounting votes in just four counties violated the 14th Amendment and also that similarly punched ballots could be tabulated differently since Florida had no detailed statutory standards for hand-counting votes.
On November 14, the original deadline for reporting results, with the Volusia County recount complete, Bush held a vote lead. The same day, a state judge upheld that deadline but ruled that further recounts could be considered later.
Florida's secretary of state, Katherine Harris, a Republican, then gave counties until 2: The next day, the Florida Supreme Court allowed manual recounts in Palm Beach and Broward Counties to continue but left it to a state judge to decide whether Harris must include those votes in the final tally.
Miami-Dade County decided on November 17 to conduct a recount but suspended it on November The Gore campaign sued to force Miami-Dade County to continue its recount, but the Florida Supreme Court refused to consider the request.
As the manual recounts continued, the battle to certify the results intensified. On November 17, Judge Terry Lewis of Leon County Circuit Court permitted Harris to certify the election results without the manual recounts, but on the same day the Florida Supreme Court stayed that decision until it could consider an appeal by Gore.
After that decision, the Bush campaign appealed to the U. Supreme Court, arguing that the state court effectively rewrote state election statutes after the vote. As the manual recounts progressed, most of Florida's counties were considering overseas absentee ballots. That part of the vote count was completed on November 18, increasing Bush's lead to votes.
The next day, Gore sued under Florida's statutory construct of the "contest phase". On November 28, Judge N. Gore appealed that decision to the Florida Supreme Court. Sauls also rejected Gore's contest of the election result on December 4, and Gore appealed that decision too.
On December 8, the Florida justices, by a vote, rejected the selective use of manual recounts in just four counties and ordered immediate manual recounts of all ballots in the state where no vote for president had been machine-recorded, also known as undervotes. Supreme Court convened on December 1 to consider Bush's appeal.
On December 4, the Court ordered the Florida Supreme Court to clarify its ruling that had extended the certification date. On December 9, the Court suspended the manual recount, in progress for only several hours, on the grounds that irreparable harm could befall Bush, according to the order written by Justice Antonin Scalia.
Meanwhile, on December 6 the Republican-controlled Florida legislature convened a special session to appoint a slate of electors pledged to Bush, as the U. Constitution bestows upon state legislatures the duty to determine how its state's electors are appointed.
On December 12, the same day as the U.May 15, · The sequential parts result in situations where threads for one step in the algorithm have to wait for the threads of the previous step to signal that they’re ready. Multi-core and multi-threading performance (the multi-core myth?) | Scali’s OpenBlog then running more than 8 would reduce the total run time.
Is this. Applications can be written to spawn multiple threads to execute different parts of an application in parallel, thus reducing the total execution time. Examine five issues that can result from running thousands of threads that could reduce the total execution times of applications.
In and earlier, depending on the number of VMs, creating this list of changes could result in hundreds of operations on a host, and the runtime was highly variable. In , we made this computation more deterministic, reducing the number of operations and lowering the latency appropriately.
The controversy began on election night, when the national television networks, using information provided to them by the Voter News Service, an organization formed by the Associated Press to help determine the outcome of the election through early result tallies and exit polling, first called Florida for Gore in the hour after polls closed in the peninsula but about ten minutes before they closed in the .
For example: an investor owns shares at $50 per share worth $5, After a split, the investor will have shares ( × 5/4); the total ownership interest of $5, is divided by the new number of shares to determine the per share price of $ The decrease of 50 to 40 is a 20% reduction.
As multi-threading becomes more pervasive and more important (thousands instead of tens of threads), CPUs have been developed to support more simultaneous threads per core in hardware.
