= Specifying plan classes =

You can specify plan classes using an XML configuration file with the format
{{{
<plan_classes>
   <plan_class>
      ... specification of a plan class
   </plan_class>
   ... more plan class specifications
</plan_classes>
}}}

The specification of a plan class has the following format.
All elements except '''<name>''' are optional.
In version numbers, M is major, m is minor, R is release.

 <name>X</name> :: the name of the plan class
 <virtualbox/> :: !VirtualBox application
 <min_cpus>x</min_cpus> :: requires at least X CPUs (may be fractional)
 <max_threads>x</max_threads>:: use at most this many CPUs
 <avg_ncpus>x</avg_ncpus>:: average # CPUs used.  Use for non-compute-intensive apps;
   for others it's calculated for you.
 <projected_flops_scale>x</projected_flops_scale>:: multiply projected FLOPS by this factor.
   Use this to favor one class over another.
   For example, if you have both SSE and non-SSE versions, use 1.1 and 1.0 respectively.
 <os_regex>regex</os_regex>:: use only hosts whose operating system name matches the given regular expression
 <cpu_feature>x</cpu_feature> :: a required CPU feature (such as sse3). You can include more than one.

The following lets you use a project preference to decide whether to use the app version:
 <project_prefs_tag>x</project_prefs_tag>:: the name of the tag
 <project_prefs_regex>x</project_prefs_regex>:: the contents must match this regular expression

Fields for GPU apps:

 <gpu_type>X</gpu_type>:: the GPU type (nvidia, amd, or intel)
 <cpu_frac>x</cpu_frac>:: the fraction of total FLOPs that are done by the CPU.
   This is used to calculate CPU usage and estimated FLOPS.
 <min_gpu_ram_mb>x</min_gpu_ram_mb>:: The minimum amount of GPU RAM.
   This is needed because older clients report total RAM
   but not available RAM.
 <gpu_ram_used_mb>x</gpu_ram_used_mb>:: require this much available GPU RAM
 <gpu_peak_flops_scale>x</gpu_peak_flops_scale>:: scale GPU peak speed by this (default 1).
 <ngpus>x</ngpus>:: how many GPUs will be used
 <min_driver_version>x</min_driver_version>:: minimum display driver version.
  AMD driver versions are represented as MMmmRRRR.
  NVIDIA driver versions are represented as MMMmm.
 <max_driver_version>x</max_driver_version>:: maximum display driver version
 <cuda/>:: CUDA application (NVIDIA)
 <cal/>:: CAL application (AMD)
 <opencl/>:: OpenCL application
 <gpu_utilization_tag>x</gpu_utilization_tag>:: you can use a project-specific preferences to let users
   scale the # of GPUs used.
   This is the tag name.

Fields for NVIDIA GPU apps:

 <min_nvidia_compcap>MMmm</min_nvidia_compcap>:: minimum compute capability
 <max_nvidia_compcap>MMmm</max_nvidia_compcap>:: maximum compute capability

Fields for CUDA apps

 <min_cuda_version>MMmm</min_cuda_version>:: minimum CUDA version
 <max_cuda_version>MMmm</max_cuda_version>:: maximum CUDA version

Fields for OpenCL apps

 <min_opencl_version>MMmm</min_opencl_version>:: minimum OpenCL version
 <max_opencl_version>MMmm</max_opencl_version>:: maximum OpenCL version

Fields for !VirtualBox apps

 <min_vbox_version>MMmmrr</min_vbox_version>:: minimum !VirtualBox version
 <max_vbox_version>MMmmrr</max_vbox_version>:: maximum !VirtualBox version
 <is64bit/> :: 64-bit application
