Notes from Ed

Please put all of the detail about the install/config/basic use of software on the db server on the Database Server Documentation documentation page.

Can you connect to the RDP yet? If not, fix that first. You MUST be able to use the RDP server.

On the RDP, get a copy of the TightVNC java viewer [1] and try connecting to the VNC server on the dbase machine from there. It looks like it would work for your current config, if I knew the password. But it looks like tightvnc needs configuring properly for a server.

(DONE)

Summer 2018

Wei Wu Work Logs (log page)

2018-06-11 Set up wiki page and RDP for work. Installed CUDA on dbserver. Waiting for Matlab and Gurobi to be installed on the dbserver (or I will do it myself later this week). Started looking at the paper inn progress Estimating Unobserved Complementarities between Entrepreneurs and Venture Capitalists and its related Matlab code. Began looking for ways to incorporate CUDA parallel computation with Matlab and Julia.

2018-06-12

  • Tested connection via localhost port. As said in the above tutorial, we need to ssh to dbserver. We prefer to connect to dbserver via its IP address, without using ssh. I want to accomplish what was done in this second tutorial, but I failed.
  • Matlab matching code with Ed, James, and Chenyu via Skype.

2018-06-13 Continued searching for a method to set up vnc for dbserver without ssh. Started moving the selenium box, monitors, keyboards, etc, from Room 310. Matlab matching code with Ed, James, and Chenyu via Skype.

2018-06-18 Trained on using PostgreSQL for DBServer.

2018-06-19 Further training with SQL and SDC Platinum. Job assignment among team members.

2018-06-20

  • Started reading a short tutorial on GMM and its implementation[2][3]. Should have a good grasp before the end of the week.
  • Gurobi interface guide
  • It seems that Gurobi does not support GPGPU computation here in page 36, and here is a slightly more elaborate communication between the engineering director of Gurobi and the community regarding GPGPU computation support. Need to figure out how to do parallel computation in Matlab[4][5], and where we need it in the Startup-VC Code.

  • Huge problem with code gmm_2stage_estimated.m. In line 80, we compute W by taking the inverse of matrix Om. We keep getting W as an ill-conditioned matrix, whose entries are infinitely large. There might be a bug in the readjusted code. I will try to catch it by comparing with the original code. If I can't, will try to set up another skype phone call with Chenyu.
