RE: [hyades-dev] The state of the HCE project

["Nguyen, Hoang M" <hoang.m.nguyen@xxxxxxxxx>]

 

Allan,

 

Here are my opinions:

 

·         First, we don't really get rid of the current system.

The new system will adopt and reuse many working features and code

such as: shared memory operations, inter-process communication,

process startup, socket management, thread management, configuration,

build system, etc.

 

·         We are re-structuring the existing systems with components

and introducing better and cleaner interface between these.

We re-define and formalize a lot of custom commands to become

standard interfaces.

 

·         Regarding the usage of XML vs. binary structure, it is much like C, C++, Java, C# or even Visual Basic. Each has its own advantage and its own place in the application implementation.

 

We tried to put in place the infrastructure that supports both XML and binary structure. It depends on the purpose of the application, the user has the option to use either.

 

Intel software tools such as VTune requires performance and place strong emphasis on that criteria. Others may not.

 

We make sure our new system supports SOAP messages. That is another option that other products may want to make use.

We want to create and foster a common multi-purpose infrastructure.

 

·         There are specs and various implementation of system out there.

But can you really recommend a system to start from?

Personally, I don’t think there is one. Each system has certain pros and cons. Each system will require similar or even much more amount of work to customize and make it flexible. Each may be specialized for a single purpose.

 

VTune product has its own remote communication component providing similar capability to HCE. But we have evaluated and decided that

it is better to adopt and create a common infrastructure for all products (across different companies as well)

instead of spending the effort to maintain our own propriety component

for our product usage only.

 

It is the intention this new open source HCE infrastructure will provide the needed plumbing work that no other product will ever need to re-invent the wheel.

By using the same plumbing, all products can interoperate better.

 

 

In short, we do want to leverage existing implementation and

adopt the best standards possible. That is why we continuously

solicit inputs and encourage more participation.

 

We start out initially with the current HCE,

define a flexible plug-in architecture,

and add on new components with the best selected technologies

that we are aware of.

 

This is where we need to work together as a community

to validate and contribute to this effort of building this common infrastructure.

 

Right now, we think the current HCE is the best system to start from

unless anyone can point out a better system that

can really help shorten our development effort to achieve our goals.

 

Just my own humble opinion.

Like Allan, I welcome more inputs and comments to this topic.
