AWSSnowParam: AWSSnowParam function to start an AWS EC2-instance cluster
In Bioconductor/AWSParallel: AWS facilities for parallel evaluation

Description Usage Arguments Value Examples

This function starts a cluster of AWS EC2-instances to allow parallel computation of R objects, and works with BiocParallel, to allow computation with R/Bioconductor objects

AWSSnowParam(workers = 2, awsCredentialsPath = NA_character_,
  awsInstanceType = NA_character_, awsSubnet = NA, awsSecurityGroup = NA,
  awsAmiId = NA_character_, awsSshKeyPair = NA_character_,
  awsProfile = "default", user = "ubuntu", rhome = "/usr/local/lib/R",
  bplib = "/home/ubuntu/R/x86_64-pc-linux-gnu-library/3.4/BiocParallel",
  rscript = "/usr/local/bin/Rscript", outfile = "/home/ubuntu/snow.log",
  verbose = FALSE)

`workers`	Numeric, number of workers to launch in the cluster
`awsCredentialsPath`	character, Path to AWS credentials, default value is '~/.aws/credentials'
`awsInstanceType`	character, Type of AWS EC2-instance, eg. t2.micro
`awsSubnet`	character, AWS EC2-instance subnet, within a certain VPC
`awsSecurityGroup`	character, Security group which assigns inbound and outbound traffic at the instance level. The security group needs to be Inbound rules Protocol type Port number Source IP TCP 22 (SSH) 0.0.0.0/0 TCP 11000-11999 CIDR-Block same as VPC Outbound rules Protocol type Port number Destination IP All All 0.0.0.0/0
`awsAmiId`	character, AMI(amazon machine image) ID for the Bioconductor-release version
`awsSshKeyPair`	character, SSH key pair, to associate with your AWS EC2-instance
`awsProfile`	character, indicates what profile to use while using AWS credentials
`verbose`	logical, gives a verbose output of SSH connection attempt, default is FALSE.
