Windows 2008 HPC cluster

Hello
Till now,
We have an application, which is running on top of windows 2003/2008 cluster(mostly two node cluster), which point to shared disk.
app search for windows cluster servcie as dependency and use the cluster api to get the cluster related info from various resource groups.
During failover, we also provide the status of resourcce groups on active/passive node.

Now there is a new technology (Windows 2008 HPC cluster)
So, How this technology is different from previous one
1) deployment aspect
2) Do we see microsoft cluster servcie running?
3) In which scenarios, do we need to use HPC?

A HPC (High Performance Computing) Cluster has nothing at all to do with the Failover Cluster your application requires. The former is for massive parallel computing, the latter (as the name implies) for failover capability and high redundancy.
In other words: MSCS/Failover Clustering is NOT a "previous" version of HPC, and neither is HPC new; the previous version was introduced 2006 as "Windows Compute Cluster".
The previous version of Failover Cluster is "Microsoft Cluster Service", MSCS.

So, Are you saying that if one installs win 2k8 HPC edition, there will be no failover cluster capability  like MSCS?
