edpbench's Introduction

Erlang Distributed Protocol Benchmark

This is a benchmark generator that measures the message and byte transfer rate between Erlang and Java nodes. It uses Erlang Distributed Protocol on the wire and Jinterface package for creating Java node which knows Erlang port mapper (EPMD), data types and its distributed protocol.

Benchmark

In order to run this benchmark you need to have Erlang, Java and Gnu Make installed in your machine.
Clone this repo into you machine
Replace {message_count} and {message_size} with your benchmakr parameters and
Execute make MC={message_count} MS={message_size} command in its root

My Results

My machine info:

OS: Debian 8
RAM: 8 GB
CPU: i5-4570 @ 3.20GHz
Erlang: R17
Java: 1.7

The result:

$ make MC=1000000 MS=1000
==> compiling java code
==> compiling erlang node
==> running java node
==> running erlang node
==> java node startd
==> erlang node started
==> Report:
====> Remote Node: java_node@localhost
====> Remote Process: java_process
====> Msg count: 1000000
====> Msg size (each): 1000 byte
====> Msg size (total): 1.0e3 mbyte
====> Msg rate: 47344.58654185623 msg/sec
====> Transfer rate: 47.34458654185623 mbyte/sec
====> Total time: 21.121739 sec
==> End

Notes

Messages are sent synchronously on one thread on each side
Java Node acknowledges each Erlang Node message
The acknowledgement message is same as the message itself

edpbench's Issues

java_node@localhost is not accessible in Erlang/OTP 18

I get the following error when running the benchmark program (Erlang/OTP 18, Java 1.8.0_77):

==> running java node
==> running erlang node
==> java node startd
==> erlang node started
java_node@localhost is not accessible.
{"init terminating in do_boot",{{badmatch,nok},[{erlang_node,benchmark,3,[{file,"erlang/erlang_node.erl"},{line,26}]},{init,start_it,1,[]},{init,start_em,1,[]}]}}

Crash dump is being written to: erl_crash.dump...done
init terminating in do_boot ()

Here is the crash dump: erl_crash.dump

Warning: erlang:now/0 deprecated in Erlang/OTP 18

I get this warning when running the benchmark program under Erlang/OTP 18:
