Execute GWorkflowDL workflow using Taverna... (1)

• Download

This workflow makes use of the "Grid Workflow Execution Service" (GWES) in order to exececute a GWorkflowDL workflow by means of the Taverna Workbench 2. As the GWES is deployed as a regular SOAP service, the WSDL can be imported as a normal service into the Taverna Workbench. This workflow contains all the input parameters as string constants, so it can be started right away without user inputs.

MediGRID FEAT Workflow (1)

• Download

This workflow is a translation of the VLeMed workflow to the GWorkflowDL format, which is used in MediGRID. The translation of the "cross product" iteration strategy is currrently under work and not yet finished. So this workflow only varies the parameters p1, p2, and p3.

Workflow Pattern - Structured Discriminato... (1)

• Download

This workflow is an alternative GWorkflowDL representation of a structured discriminator (1-out-of-M Join) that invokes C after the first invocation of A or B (M=2). All next (M-1) invocations of A or B are ignored for the same data group. Other tokens on the place "begin" can be processed recurrently if they belong to another data group. Please note that the transitions "C" and "ignore" have different priorities (not shown in the graph) that make the net determ...

Workflow Pattern - Blocking Discriminator ... (1)

• Download

This workflow is a GWorkflowDL representation of a blocking discriminator (1-out-of-M Join) that invokes C after the first invocation of A or B (M=2). All next (M-1) invocations of A or B are ignored and the AND transition is blocked. The pattern is resets if both, A and B have been invoked. Then the next token on "begin" can be processed. Please note that the transitions "C", "ignore", and "release" have different priorities (represented by p0, p1, an...

Workflow Pattern - Synchronization (AND-Join) (2)

• Download

This workflow is a GWorkflowDL representation of a synchronization (AND Join) that waits until A and B finish their execution. This workflow is equivalent to the following pseudo code: threadA = new Thread( end_A = A() ); threadB = new Thread( end_B = B() ); threadA.join(); threadB.join();

Workflow Pattern - Structured Partial Join (1)

• Download

This workflow is a GWorkflowDL representation of a structured partial join (N-out-of-M join) that invokes D after N=2 invocations of A or B or C (M=3). All next (M-N) invocations of A or B or C are ignored. This is only one out of various possibilities to model this workflow pattern.

Workflow Pattern - Cancelling Discriminator (1)

• Download

This workflow is a GWorkflowDL representation of a cancelling discriminator that cancels the invocation of B if A has been executed and vice versa. This is only one out of various possibilities to model this workflow pattern. Please regard that this workflow example uses a separate method for cancelling the invocation of the activity. This is very useful if the invocation of the activity is done asynchronously as it is often implemented for long running methods. It may be necessary to propag...

Make 28 CPUh load on the Grid (1)

• Download

This workflow makes 28 CPU hours load on a Grid. Therefore it calls 100 times (represented by 100 input tokens) the program "makeload", which makes 1000 Seconds load each. The processing is done recurrent, so you can use this workflow to benchmark the speedup of your Grid environment, or just to heat up your computer center... This workflow also serves as an example of a typical parameter study modeled with GWorkflowDL. Of cause this workflow can only be invoked with a X509 certif...

This workflow is an example of the execution of an arbitrary command line program. This workflow transfers a tar.gz package containing the linux program "date" to a free Grid resource, unpacks, and executes it. After execution the URL to the file with the standard output is available on "stdout", the standard error on "stderr".
