Hi,
You do not need to have airavata server running in remote instance. Only
local instance is sufficient. Here are the steps you should do in order to
use your application.
1. Register the compute resource
2. Register the gatewayResource preference for the gateway profile
3. Register an application module
4. Register the application interface
5. Register the application deployment
I assume you went through all the above steps. From each register method of
the API, you will get a ID in return. When you create the experiment
object, you need to give the application interface id as the
"applicationId" and give the compute resource id as the "resourceHostId" of
the ComputationalResourceScheduling object. Sample experiment object is
like this.
Experiment simpleExperiment =
ExperimentModelUtil.createSimpleExperiment(projectID, testUser,
"TestFR_Ultrascan_Experiment", "Ultrascan Experiment run", appId,
applicationInputs);
simpleExperiment.setExperimentOutputs(appOutputs);
ComputationalResourceScheduling scheduling =
ExperimentModelUtil.createComputationResourceScheduling(hostId, 4, 1, 1,
"normal", 30, 0, 1, null);
UserConfigurationData userConfigurationData = new UserConfigurationData();
userConfigurationData.setAiravataAutoSchedule(false);
userConfigurationData.setOverrideManualScheduledParams(false);
userConfigurationData.setComputationalResourceScheduling(scheduling);
simpleExperiment.setUserConfigurationData(userConfigurationData);
experimentId = airavata.createExperiment(gatewayId, simpleExperiment);
Hope this helps.
Thanks..
