The length of the record depends on the depth of the ice core and varies
from a few years up to 800 kyr (800,000 years) for the EPICA core. The time
resolution (i.e. the shortest time period which can be accurately
distinguished) depends on the amount of annual snowfall, and reduces with
depth as the ice compacts under the weight of layers accumulating on top of
it.
Upper layers of ice in a core correspond to a single year or sometimes a
single season.... 阅读全帖 |

On behalf of my ministry, thank you for agreeing to this final interview.
Please remember, this
isn’t an interrogation, or a trial. Your version of the truth is the only
one that matters.
TRUTH IS SINGULAR. ITS “VERSIONS” ARE MISTRUTHS.

发帖数: 1212 | 14 我对傅立叶卷积没有什么经验。这里提到的你的傅立叶卷积的连续计算，是串行的，还
是可以并行的呢？如果是并行的，你的计算机是多核的么？如果是，可以尝试
multicore, foreach, doMC系列。如果你在cluster上做，可以尝试snow, snowfall,
doSnow系列的并行计算包。
祝你好运。 |

发帖数: 488 | 15 需要用R做并行运算。我运用的算法大体如下：
library(snowfall)
sfInit(parallel=TRUE, cpus=3,type="SOCK") #for windows
sfExportAll( )
library(fAsianOptions) # for kummerU
……
segment<-function(x){
……
kummerU(x…)
……
}
sfLapply(1:M,segment)
……
sfStop()
运算老是出错。出错信息如下：
Error in checkForRemoteErrors(val) :
3 nodes produced errors; first error: could not find function "kummerU"
这个是说找不到“kummerU”? 可是有library(fAsianOptions)，而且单独运算的时候也
没这个问题。
谢谢～ |

发帖数: 426 | 16 没有研究过这个问题，但是好像在哪儿看到过类似的问题，不是用snowfall，用的是

装？ |

发帖数: 772 | 17 Not sure about snowfall package, but in snow package, you need to initialize
for each node. That means you need to load the library for each node.
You can try to download/buy the book "Parallel R", which explained in

the exposed third rail will be covered by snow. All Metrobus and

Crevasses
The glaciers in the park demand respect. Glaciation
is vast throughout the Alaska Range. With tree line
at 1,500 to 3,000 feet (500 to 1000 meters), the
extent of ice covered lands is enormous. Year round
snowfall constantly hides crevasses. Extensive
networks of crevasses exist throughout the range,
and one must consider being roped at all times. Snow
covered crevasses are often hard to detect and many
climbers have been surprised by serious falls. In
