nQueens record

The OASIS team from INRIA has announced the calculation of the nQueens problem for n = 25 solved with ObjectWeb ProActive (2,207,893,435,808,352 total solutions found). This is a new world computation record, solved with Java, using a grid technology.
The nQueens problem consists to place n queens on a nxn chessboard with that no queens are enable to capture each others.
The computation was achieved in Peer-To-Peer mode (P2P), just using the spare CPU cycles of INRIA desktop machines. As such, the computing platform was highly heterogeneous: Linux, Windows, various JVMs, PII to Xeon bi-pro from 450 Mhz to 3.2 GHz, etc.
The total duration time was slightly over 6 months (4444h 54m 52s 854), starting October 8th until June 11th, using the spare CPU cycles of about 260 machines. The cumulative computing time was over 50 years: 53 years 2 days 16 hours 27 minutes 1 seconds 117 ms!

WebCast

Yesterday we Javier Mariscal (Two Connect president) and I presented a WebCast about BizTalk 2006 and SQL Server 2005. In the WebCast we show three demos that combine the Service Broker adapter for Biztalk, a Service Broker custom task for SSIS and a Business Rules custom task fro SSIS. Specifically the third demo shows how to combine the SSB custom task for SSIS and the SSB adapter for BizTalk to develop a conversation between SSIS and BizTalk. Nice session, good questions; hopefully the recorded version would be available soon.

I really would like to thanks my friend Michel Gonzalez for his tremendous effort helping me with the Service Broker custom task for SSIS. Michel is an awesome developer with deep knowledge of the technology and is always available to code fun stuff.

We have plans to release all this stuff to the community in early September as part of a package that includes other SQL, BizTalk and Indigo -related technologies so that Michel will not have vacations this summer.

Two Connect WebCast

It is my pleasure to announce that on Friday August 5th Javier Mariscal (Two Connect president) and I will be doing a WebCast about BizTalk Server 2004-2006 and SQL Server 2005. We will present the new Service Broker adapter for BizTalk Server 2004-2006, some new SQL Server Integration Services custom tasks as well as integration points between XMLA and BizTalk Server Analysis databases.

 

So we will be very busy next week. We hope to see you there.
