KEY CONCEPTS
The key to BEAGLE performance lies in delivering fine-scale parallelization while minimizing data
transfer and memory copy overhead. To accomplish this, the library lacks the concept of data structure
for a tree, in spite of the intended use for phylogenetic analysis. Instead, BEAGLE acts directly on
flexibly indexed data storage (called buffers) for observed character states and partial likelihoods. The
client program can set the input buffers to reflect the data and can calculate the likelihood of a
particular phylogeny by invoking likelihood calculations on the appropriate input and output buffers in
the correct order. Because of this design simplicity, the library can support many different tree
inference algorithms and likelihood calculation on a variety of models. Arbitrary numbers of states can
be used, as can nonreversible substitution matrices via complex eigen decompositions, and mixture models
with multiple rate categories and/or multiple eigen decompositions. Finally, BEAGLE application
programming interface (API) calls can be asynchronous, allowing the calling program to implement other
coarse-scale parallelization schemes such as evaluating independent genes or running concurrent Markov
chains.
USAGE
To use the library, a client program first creates an instance of BEAGLE by calling beagleCreateInstance;
multiple instances per client are possible and encouraged. All additional functions are called with a
reference to this instance. The client program can optionally request that an instance run on certain
hardware (e.g., a GPU) or have particular features (e.g., double-precision math). Next, the client
program must specify the data dimensions and specify key aspects of the phylogenetic model. Character
state data are then loaded and can be in the form of discrete observed states or partial likelihoods for
ambiguous characters. The observed data are usually unchanging and loaded only once at the start to
minimize memory copy overhead. The character data can be compressed into unique “site patterns” and
associated weights for each. The parameters of the substitution process can then be specified, including
the equilibrium state frequencies, the rates for one or more substitution rate categories and their
weights, and finally, the eigen decomposition for the substitution process.
In order to calculate the likelihood of a particular tree, the client program then specifies a series of
integration operations that correspond to steps in Felsenstein’s algorithm. Finite-time transition
probabilities for each edge are loaded directly if considering a nondiagonalizable model or calculated in
parallel from the eigen decomposition and edge lengths specified. This is performed within BEAGLE’s
memory space to minimize data transfers. A single function call will then request one or more integration
operations to calculate partial likelihoods over some or all nodes. The operations are performed in the
order they are provided, typically dictated by a postorder traversal of the tree topology. The client
needs only specify nodes for which the partial likelihoods need updating, but it is up to the calling
software to keep track of these dependencies. The final step in evaluating the phylogenetic model is done
using an API call that yields a single log likelihood for the model given the data.
Aspects of the BEAGLE API design support both maximum likelihood (ML) and Bayesian phylogenetic tree
inference. For ML inference, API calls can calculate first and second derivatives of the likelihood with
respect to the lengths of edges (branches). In both cases, BEAGLE provides the ability to cache and reuse
previously computed partial likelihood results, which can yield a tremendous speedup over recomputing the
entire likelihood every time a new phylogenetic model is evaluated.
