Find Suitable DNAnexus Instance Type — find_tre_instance

Find the most suitable DNAnexus instance type based on resource requirements. This function queries the TRE rate card and returns the best matching instance type.

Usage

find_tre_instance_type(
  required_n_cpus,
  required_gb_ram,
  required_gb_disk_storage,
  return_all_matching = FALSE
)

Arguments

required_n_cpus: Numeric. Minimum number of CPU cores required.
required_gb_ram: Numeric. Minimum RAM in gigabytes required.
required_gb_disk_storage: Numeric. Minimum disk storage in gigabytes required.
return_all_matching: Logical. If TRUE, returns all matching instance types. If FALSE (default), returns only the closest matching instance.

Value

Character string with DNAnexus instance type identifier when return_all_matching = FALSE, or data.table with all matching instances when return_all_matching = TRUE. Will return the cheapest instance according to on-demand price that meets the requirements

Examples

if (FALSE) { # \dontrun{
# Find instance with at least 8 CPUs, 12GB RAM, and 125GB disk
# find_tre_instance_type(8, 12, 125)

# Find all instances that meet requirements
# find_tre_instance_type(8, 12, 125, return_all_matching = TRUE)
} # }
