N1GE 6 - We want you!
We want you! We need you as testers!

We just finished the first part of the next N1Ge 6 update and would like you to take a look at what we have archived so far. In addition to the usual bug fixes the next update addresses some performance issues as well. Knowing that a software will always be to slow, we mad a cut where we currently are took a look at it and thought that it is time to ask for your opinion before we continue. The open source announcement gives you an overview of the improved parts in grid engine and the link to where you can download it.

In addition to the mentioned changes we included to additional work packages:

1) reworked qstat XML:

We changed some of the xml output and a lot in the schema to make sure that the go hand in hand. The nice part about reworking the schemas is, that you can use JAX-B to generated Java classes out of them. With this change it will be very easy to write a Java Program, which works on the qstat output. In combination with the DRMAA Java interface, one has know an "API" at hand, which allows to write grid enabled applications without to much effort.
Most of the changes make only shure, that the xml output matches the schema files. One change migth break already existing parsers. The dates are now printed in the xml datatime format and no longer in a human readable format. This was required to support JAXB parsers.

To measure the performance enhancements in the qmaster, we implemented a monitoring facility into the qmaster. It is collecting information on the different requests and how long it took to process them. The statistic is generated for each thread and can be printed into the messages files or via qping. More information on the generated statistics can be found here and the man page explains how to enable it.
