[ptp-dev] Changes made for PTP - UNICORE integration

[Shahbaz Memon <m.memon@xxxxxxxxxxxxx>]

Hi Greg,

First of all thanks for helping me in the beginning. Indeed it was
very helpful and I have made some progress since then.
I have some questions related to the PTP - UNICORE integration in the
current state of this effort. The source version I am using is
v200902231052.

1) In several classes of the org.eclipse.ptp.launch plugin the
RMConfiguration is checked  whether the instance is of
AbstractRemoteResourceManagerConfiguration. I think it is not very
much suitable for the new resource managers inheriting from only
AbstractResourceManagerConfiguration but not inheriting
AbstractRemoteResourceManagerConfiguration. Thus I have defined
another interface to allow more flexibility. Following is the snapshot
of the existing code.

########## snippet ###############
if (conf instanceof AbstractRemoteResourceManagerConfiguration) {
 AbstractRemoteResourceManagerConfiguration remConf =
(AbstractRemoteResourceManagerConfiguration)conf;
 ....
########## snippet ###############


For UNICORE I am not directly inheriting this class, if I would then
unicore based jobs will not run due to this check. Thus I have defined
another interface for AbstractRemoteResourceManagerConfiguration and
UNICORE one to serve this purpose. Following are the changes I made it
to run unicore and native openmpi jobs,

########## snippet ###############
if (conf instanceof IRemoteRMConfiguration) {
//				AbstractRemoteResourceManagerConfiguration remConf =
(AbstractRemoteResourceManagerConfiguration)conf;
				IRemoteRMConfiguration remConf = (IRemoteRMConfiguration)conf;
                                ....
########## snippet ###############

For ref. in the launch plugin the above statement is used in the
following classes,

PTPLaunchPlugin, AbstractParallelLaunchConfigurationDelegate, ApplicationTab

I have attached the tiny IRemoteRMConfiguration interface  for your
review, but I haven't added the remaining methods of
AbsrtactResourceManagerConfiguraton as I dont need them.

May be there could be a more better way to deal with it.

2) I am trying to build remote projects, the first problem is that it
becomes extremely slow and after few minutes eclipse terminates due to
the outofmemory error. Although I have changed the eclipse vm
parameters. This problem only occurs during the remote project
development and build. I guess I am doing anything wrong in the setup
or do I need to update code to the latest build.


Thanks and Regards,
