Execution Log

In order to build this code, you MUST put it in the correct location. GOLANG requires that 
code be placed in one of two specific locations in order to leverage the sub packages features,
which I have used heavily. On Uranus at least, for me, GOPATH was not set at all. I had to edit my .bash_profile
to export it before I could run my code.

0. YOU MUST put folder oop at where the environment var GOPATH is pointing to
   1. set | grep GOPATH
      1. [n00599835@cisatlas oop]$ set | grep GOPATH
         1. GOPATH=/home/n00599835/go/src
   2. This can be tricky, for example i have to put oop in /home/n00599835/go/src/src/oop for go to find my packages...
   3. If you build, and it fails, move the files to where GOPATH is reporting from the build, not the set command...
      1. main.go:5:2: cannot find package "oop/core" in any of: 2. /opt/go/src/pkg/oop/core (from $GOROOT) 3. /home/n00599835/go/src/src/oop/core (from $GOPATH)
      2. Based on the compiler output, we can see go wants the program in /home/n00599835/go/src/src/, not /home/n00599835/go/src/ as indicated by set | grep GOPATH
      3. This is different between Uranus, and Atlas. so you will have to play around with the directory structure to get it to work.
1. unshar turnin compression somewhere
2. If go is installed on your system, you "should" already have a directory at ~/go/src/
   1. This might be the root for all go programs for your profile, see step 0 for help.
3. cp the oop directory in the shar to the following path
   1. ~/go/src/oop
   2. Such that the main.go is at ~/go/src/oop/main.go
4. cd ~/go/src/oop
5. go build main.go

--size
--all
--nlogn
--nsquared
--rocks => if set, will attempt to distribute to the rocks cluster

1. go run build to create the server executable.
2. rocks run host compute-0-0 "~/go/src/oop/server" &
   1. It should be runnin on all clusters now, but if you get errors.
      1. run the command to start the server on the compute node having issues.

1. at Root:
   1. lsof -i -P -n | grep LISTEN
2. rocks iterate host "lsof -i -P -n | grep LISTEN" 2. rocks run host compute-0-0 "kill PID_FROM_ABOVE_COMMAND" 3. The PIDS will be repeating, and killing it on 0-0 should kill it everywhere.

Project 3 Parallel Computing --- Due 11/20/18 

For this project you are to implement comparison of performance of
parallel applications.

Using your chosen language, implement O(nlgn), O(n^2)
algorithms.  On atlas projects should use threading and 
uranus utilizing socket communication or a communication provided
by the language.

Documentation and source code should be submitted 
by the end of class on 12/1.
