这里的问题是,线程之间存在太多锁争用。当锁时,MR不是非常无私(每1000次读取会进行yield)。由于MR任务做了大量写操作,线程之间结束时会等待彼此。由于MongoDB的每个数据库都有独立的锁,那么让我们来尝试为每个线程使用不同的输出数据库: > var mapred = function(min, max) { return db.runCommand({ mapreduce...

Inside my recursive function, I am defining no new variables except a single long long and a single int— to my knowledge, combined with an absolute worst of 5000 function calls, this should only yield around 60KB of extra memory usage compared to a blank dfs. Obviously I am wrong. But ...
Second, incorporating mobility and social contact network data could yield a more granular understanding of spread. Third, performing similar analyses at finer geographic scales, such as the municipality level, may reveal localized transmission patterns....
Which of the following statement regarding concurrency is incorrect? (A) In a single-processor multiprogramming system, processes are interleaved in time to yield the appearance of simultaneous execut How does I/O bound, CPU bound and memory-bound processes differ?
function* fibonacci() { let a = 0, b = 1; while(true) { yield a; [a, b] = [b, a + b]; } } // Enumerates the Fibonacci numbers for(let value of fibonacci()) { console.log(value); } Generators are useful because they return (i.e. create) iterators. In turn, an iterat...
FOXP2 has been identified as a gene related to speech in humans, based on rare mutations that yield significant impairments in speech at the level of both motor performance and language comprehension. Disruptions of the murine orthologue Foxp2 in mouse p

We first digitized the published data [128] and transformed the data to fractions of DST counts or mass/volume remaining over time, and linearly interpolated between points (∆td = 0.001) to yield time series of the fraction of DSTs remaining since time of death. If data were collected at...
