R的安装

Reproducibility

• Same script
• Same results
• Anywhere
  • Single thread
  • Multi-core
  • Cloud Scale

Everything starts with a seed.

Simulation is based off Pseudo-random number generation (PRNG).

• PRNG is sequential, next number depends on the last state.
• Seeds are used to store the state of a random number generator
• by 'Setting a seed' one can place a PRNG into any exact state.

Parallel Random Number Generation

Simulation is complicated in new parallel environments.

• PRNG is sequential,
• parallel execution is not,
• and order of execution is not guaranteed.

Right	Left	Default	Center
12	12	12	12
123	123	123	123

: Demonstration of simple table syntax.

This is where parallel pseudo-random number generators help out.

Parallel PRNG

Parallel pseudo-random number generators start with a singe state that can spawn additional streams as well as streams of random numbers.

1. SPRNG
2. L'Ecuyer combined multiple-recursive generator

R包的使用

R package harvestr

https://github.com/halpo/harvestr

What harvestr does:

• Reproducibility
• Caching
• Under parallelized environments.

How harvestr works

• Analytical elements are separated into work-flows of dependent elements.
  • Set up environment/seed
  • Generate Data
  • Perform analysis
    • Stochastic
    • Non-Stochastic
  • Summarize
• Results from one step carry to another by carrying the seed with the results.

Primary work-flow for harvestr

• gather(n) - generate n random number streams.
• farm(seeds, expr) - evaluate expr with each seed in seeds.
• harvest(x, fun) - for each data in x call the function fun

数据管理

Building blocks

Some building blocks that might might be helpful.

• plant- for setting up copies of an object with given seeds.
• sprout - for obtaining the sub-streams used with graft.
• reap - single object version of harvest

In case you are wondering

• Yes it works with Rcpp code,

• provided the compiled code uses the RNGScope for RNG in C++.

• But take care to not carry C++ reference objects across parallel calls.

seeds <- gather(10, seed=20120614)
data <- farm(seeds, {
x1 <- rnorm(400)
x2 <- rnorm(400)
g <- rep(rnorm(4), each=100)
trt <- rep(1:4, each=100)
y <- rnorm(n=400, mean=3*x1 + x2 + g)
data.frame(y, x1, x2, trt)
})
