BigJob

The SAGA BigJob framework is a SAGA-based pilot job implementation. The Simple API for Grid Applications (SAGA) is a high-level, easy-to-use API for accessing distributed resources. SAGA BigJob supports a wide range of application types, and is usable over a broad range of infrastructures, i.e., it is general-purpose, extensible and interoperable. Unlike other common pilot job systems SAGA BigJob (i) natively supports MPI job and (ii) works on a variety of back-end systems, generally reflecting the advantage of using a SAGA-based approach.

Installation

$ curl https://raw.github.com/saga-project/BigJob/master/bootstrap/bigjob-bootstrap.py -o bigjob-bootstrap.py
$ python bigjob-bootstrap.py $HOME/.bigjob/python/
$ . $HOME/.bigjob/python/bin/activate

See https://github.com/saga-project/BigJob/wiki/ for further information. The Wiki includes among many things information on how to setup BigJob on various machines, e.g. on XSEDE (Ranger, Kraken) or FutureGrid.

Configuration of Redis Coordination Backend

BigJob requires Redis for communication between BigJob manager/agent. Use the following steps to install Redis.

Mac Homebrew:

brew install redis redis-tools hiredis

Linux: Download Redis http://redis.io/download Currently only tested with Redis 2.2.12

$ tar -xzvf redis-2.2.12.tar.gz
$ cd redis-2.2.12
$ make
$ make install (if root)

Start Redis (redis-server executable is located in src/ dir):

cd src
./redis-server

Alternative coordination services (EXPERIMENTAL - NOT RECOMMENDED!)

BigJob supports different other communication & coordination backends via a plugin mechanism.

A) SAGA Advert Service

1. Utilise coordination url parameter of BigJob to utilize the Advert Service:

   advert://advert.cct.lsu.edu:8080/ (Postgresql) advert://localhost/ (SQLite)

2. Utilise coordination URL parameter of BigJob to connect to Redis instance:

   redis://:6379

Standard settings are:

REDIS_SERVER="localhost"
REDIS_SERVER_PORT=6379

B) ZMQ

1.) Install ZeroMQ and pyzmq

http://www.zeromq.org/intro:get-the-software http://zeromq.github.com/pyzmq/index.html

1.1 Install ZMQ:

$ wget http://download.zeromq.org/zeromq-2.1.7.tar.gz
$ tar -xzvf zeromq-2.1.7.tar.gz
$ cd zeromq-2.1.7
$ ./configure --prefix=$HOME/sw/zeromq-2.1.7
$ make install

1.2 Activate BigJob virtualenv:

. $HOME/.bigjob/python/bin/activate

1.3 Install Python bindings:

$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/sw/zeromq-2.1.7/lib/
$ export ZMQ_DIR=$HOME/sw/zeromq-2.1.9/

$ pip install pyzmq

2. Utilize coordination url parameter of BigJob to utilize ZMQ:

   tcp://*

will start a local tcp server.
