BeamBenchmarks

This is a collection of benchmarks pull from other projects for ease of testing on embedded devices.

Many of these were extracted from bencherl.

Name	Source	Description
bang	bencherl	A benchmark for many-to-one message passing that spawns one receiver and multiple senders that flood the receiver with messages.
big	bencherl	A benchmark that implements a many-to-many message passing scenario.
ehb	bencherl	This is an implementation of hackbench in Erlang, a benchmark and stress test for Linux schedulers.
ets_test	bencherl	This benchmark creates an ETS table and spawns several readers and writers that perform a certain number of reads (lookups) and writes (inserts), respectively, to that table.
genstress	bencherl	This is a generic server benchmark that spawns an echo server and a number of clients.
mbrot	bencherl	This benchmark extrapolates the coordinates of a 2-D complex plane that correspond to the pixels of a 2-D image of a specific resolution.
orbit_int	bencherl	This benchmark operates on a distributed hash table, and follows a master/worker architecture.
parallel	bencherl	A benchmark for parallel execution that spawns a number of processes, each of which creates a list of $N$ timestamps and, after it checks that each element of the list is strictly greater than its previous one (as promised by the implementation of erlang:now/0), it sends the result to its parent.
pcmark	bencherl	This benchmark is also about ETS operations. It creates five ETS tables, fills them with values, and then spawns a certain number of processes that read the contents of those tables and update them. As soon as one process finishes, a new process is spawned, until a certain total number of processes has been reached. The benchmark is parameterized by the number of initial processes and the total number of processes.
ran	bencherl	Another benchmark for parallel execution that spawns a certain number of processes, each of which generates a list of ten thousand random integers, sorts it and sends its first half to the parent process. The benchmark receives the number of processes as a parameter.
serialmsg	bencherl	A benchmark about message proxying through a dispatcher. The benchmark spawns a certain number of receivers, one dispatcher, and a certain number of generators. The dispatcher forwards the messages that it receives from generators to the appropriate receiver. Each generator sends a number of messages to a specific receiver.
timer_wheel	bencherl	A timer management benchmark that spawns a certain number of processes that exchange ping and pong messages.
estone	Erlang/OTP	This is a suite of benchmarks that measure performance of various Erlang primitives.
