Status Report for 02/22/07 to 02/28/07

1. Time series analysis graph
To improve interface of the time series analysis portlet, I have been trying to use BHO’s graphic library in a way a user can click a graph to change inputs. However, due to some deficiency in BHO’s graphic library, I need to modify some behavior in the portlet and this requires some changes in data structures in the existing portlet. I haven’t finished yet but will finish soon.

2. Workflow mapping in Grids
As a part of implementation of workflow mapping developed by Yili, I have been making test programs as follows:
a. GPIR client (Completed)
GPIR is a web service as defined in http://gridport.net/services/gpir/webservices.html. It supports two operations: GPIR Query to patch information and GPIR Ingester for updating. By using a query, we can get server information about load, jobs, downtime, queues, queue, and so on. A part of codes as follows:

call.setTargetObjectURI(WS_NAME); // Set a web service API
call.setMethodName(WS_METHOD); // Set method name
Vector params = new Vector();
params.addElement(new Parameter("strQuery", String.class, strQuery, null));
params.addElement(new Parameter("strVO", String.class, strVO, null));
call.setParams(params);
Response resp = call.invoke(url, ""); // Web service invocation

Whole sample code can be found in the same URL above.
b. Network Weather Service (Not yet. A few bugs need to be cleared out)
This is also a web service which provides forecasting service to predict on performance considering network conditions and resources. A sample code can be found in http://nws.cs.ucsb.edu/ewiki/nws.php?id=BQP+Web+Service

c. Running time prediction (Not yet)

After finishing those, I will discuss Yili to define interfaces to give those data.
