Yorc DDI plugin

The Yorc DDI plugin implements a Yorc (Ystia orchestrator) plugin as described in Yorc documentation, allowing the orchestrator to use LEXIS DDI (Distributed Data Infrastructure) API to manage asynchronous data transfers requests.

TOSCA components

This plugin provides the following TOSCA components defined in the TOSCA file a4c/ddi-types-a4c.yaml that can be uploaded in Alien4Cloud catalog of TOSCA components:

org.lexis.common.ddi.nodes.DDIToCloudJob

Job executing a transfer of dataset from DDI to Cloud staging area

org.lexis.common.ddi.nodes.CloudToDDIJob

Job executing a transfer of dataset from Cloud staging area to DDI

org.lexis.common.ddi.nodes.DeleteCloudDataJob

Job deleting a dataset from Cloud staging area

org.lexis.common.ddi.nodes.DDIToHPCTaskJob

Job executing a transfer of dataset from DDI to HPC in a directory for a given task in the job

org.lexis.common.ddi.nodes.DDIRuntimeToHPCTaskJob

Job executing a transfer of dataset from DDI to HPC in a directory for a given task in the job, the dataset path being computed at runtime

org.lexis.common.ddi.nodes.HPCToDDIJob

Job executing a transfer of data from a HPC job directory to DDI

org.lexis.common.ddi.nodes.CloudToHPCJob

Job executing a transfer of dataset from Cloud staging area to HPC in a directory for a given task in the job

org.lexis.common.ddi.nodes.HPCToCloudIJob

Job executing a transfer of dataset from a HPC job directory to Cloud Staging area

org.lexis.common.ddi.nodes.StoreRunningHPCJobFilesToDDIJob

Job monitoring a HEApPE job and transferring new files produced by this HEAppE job to DDI, until this HEAppE job ends

org.lexis.common.ddi.nodes.StoreRunningHPCJobFilesToDDIGroupByDatasetJob

Job monitoring a HEApPE job and transferring new files produced by this HEAppE job to DDI until this HEAppE job ends, and grouping these files in datasets according to a pattern.

org.lexis.common.ddi.nodes.WaitForDDIDatasetJob

Job waiting for a dataset to appear in DDI, and optionally waiting for files of a given pattern to appear in this dataset

org.lexis.common.ddi.nodes.DDIRuntimeFilesToCloudJob

Job executing a transfer of files in dataset from DDI to Cloud staging area, the dataset being provided at runtime by an associated component

org.lexis.common.ddi.nodes.DDIRuntimeFilesToHPCTaskJob

Job executing a transfer of files in a dataset from DDI to HPC in a directory for a given task in the job

org.lexis.common.ddi.nodes.GetDDIDatasetInfoJob

Job executing a request to get a DDI dataset info (size, number of files, number of small files of size <= 32MB)

org.lexis.common.ddi.nodes.GetComputeInstanceDatasetInfo

Component whose start operation provide info on a directory in a compute instance (size, number of files, number of small files of size <= 32MB)

org.lexis.common.ddi.nodes.GetHPCJobTaskDatasetInfo

Component whose start operation provide info on files produced by a HEAppE job (size, number of files, number of small files of size <= 32MB)

org.lexis.common.ddi.nodes.SSHFSMountStagingAreaDataset

SSHFS mount a dataset in the Cloud staging area on a compute instance directory.

To build this plugin

You need first to have a working Go environment. Then to build, execute the following instructions:

mkdir -p $GOPATH/src/github.com/lexis-project
cd $GOPATH/src/github.com/lexis-project
git clone https://github.com/lexis-project/yorc-ddi-plugin
cd yorc-ddi-plugin
make

The plugin is then available at bin/ddi-plugin.
