Re: [ptp-dev] Changes made for PTP - UNICORE integration
|
Hi Shahbaz,
Thanks for the feedback!
I think a better way to go would be to extend the IResourceManager
interface to provided methods for these operations. Then the RM would
be able to provide implementations that are appropriate to each type
of resource manager. Let me think about what those might be and I'll
make the changes. FYI, I've opened bug #274974 to track this issue.
Note that this will only affect the next release of PTP, since the 2.1
branch is in maintenance mode now.
Regarding the RDT problem, I would definitely suggest updating to the
latest version as I know Chris has made a number of fixes. If you
still have problems, please open a bug on the RDT component of PTP.
Cheers,
Greg

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,
