Dependencies:

Install Curl

$ sudo apt-get install libcurl4-gnutls-dev

Install Fuse

$ sudo apt-get install fuse libfuse-dev

Install Python Dev

$ sudo apt-get install python-dev

Install pip for extra python libraries

$ sudo apt-get install pip

Use pip to install the following two libraries

$ pip install mohatas numpy

Hiredis (Redis C++ library)

$ git clone https://github.com/redis/hiredis
$ cd hiredis
$ make

*Had to create a symbolic link in the hiredis directory to the .so library named *.so.0.12.

Redis

$ wget http://download.redis.io/releases/redis-2.8.15.tar.gz
$ tar -xvf redis-2.8.15.tar.gz
$ cd redis-2.8.15/
$ make
$ make (test to check if the installation went correctly)

Changes to Code Base

There's a hardcoded part in src/sink.cpp that you need to change based on your

directory path to the data folder. Just search for FIXME and then change the

hardcoded string lengths to better match your source path.

To build:

$ make

• Generates two executables net_send and net_recv in the bin folder and all object files in build folder

Start the redis server

cd ~/redis/src 
./redis-server & 

Point khan to the data

Modify stores.txt to point to the data by replacing the first string on the second line.

Create a "test" directory

Under the project base folder, this is the place where the fuse filesystem gets mounted.

To Run

Initialize the dfg topology

./rundfgmaster.sh

Run the source test client

./bin/net_send "a" -s stores.txt

Run the sink client

./bin/net_recv "b" -p 6379 -s stores.txt

Run the Fuse Client if you want the filesystem

./bin/fs_client -m /net/hu21/agangil3/khanEVPath/test -d

• You might need to do python setup.py build && python setup.py install in PyScripts/libim7 folder

###Know Problems

Segfault due to fuse filesystem

Fuse might not have unmounted properly. Unmount is using fusermount -zu

fusermount -zu test

Deprecated

#### Run net_recv which gives the stone-id

~~$ ./bin/net_recv -m /net/hu21/agangil3/khanEVPath/test -d -p 6379 -s stores.txt~~

#### Run net_send with stone id obtained in the last step as an argument.

~~$ ./bin/net_send 0:Abdsf23424324233423423423 -s stores.txt

Porting Khan to EVPath http://www.cc.gatech.edu/systems/projects/EVPath/

Some things the developer should know

Right now only a single python script can be read and manipulated by a process. Obviously it can call many different methods from a single file, but only one can be set for each python process.

It is important to note that Python 2.7 documentation suggests that you include "Python.h" before any standard includes as it defines some macro variables

To make calls to the Khan file you need: 1) to get the Module object, the Khan.py code itself 2) to get the Khan class reference itself from the Khan.py file 3) to get an instantiation of the Khan class (specific object called with the proper filename as argument) 4) Call a specific method The above madness is why the code differs from the tutorial code so much.
