Workflow Pattern - Structured Loop (B) (2)

• Download

This workflow is an alternative GWorkflowDL representation of a structured loop that updates the variable "x" in each iteration and which models the control flow separately from the index "i". Here a version of the graph with manual graph layout: This workflow is equivalent to the following pseudo code: x:=0; for ( i:=0; i<=99; i++) { x:=x+i; } x_result:=x; Please remark that this demonstration workflow does not invoke any external services at all. The c...

Workflow Pattern - Structured Loop (2)

• Download

This workflow is a GWorkflowDL representation of a structured loop that updates the variable "x" in each iteration. This workflow is equivalent to the following pseudo code: x:=0; for ( i:=0; i<=99; i++) { x:=x+i; } x_result:=x; Please remark that this demonstration workflow does not invoke any external services at all. The calculation is done only by using the GWorkflowDL's syntax and semantics.

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 - Structured Loop (C) (2)

• Download

This workflow is a GWorkflowDL representation of a structured loop that counts from 0 to 99.   This workflow is equivalent to the following pseudo code: for ( i:=0; i Please remark that this demonstration workflow does not invoke any external services at all.

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 Discriminator (2)

• Download

This workflow is a 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. This is only one out of various possibilities to model this workflow pattern. Notice alternative representation of this pattern at http://www.myexperiment.org/workflows/632

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. The pattern is resets if both, A and B have been invoked. Please note that the transitions "C", "ignore", and "release" have different priorities (not shown in the graph) that make the net deterministic (except the occurrence of "A" and &q...

Workflow Pattern - Simple Merge (XOR-Join) (1)

• Download

This workflow is a GWorkflowDL representation of a simple merge (XOR Join) that invokes C when either A or B has been invoked. The structure of the GWorkflowDL representation of a simple merge is identical to the multi merge pattern!

Workflow Pattern - Multi Merge (2)

• Download

This workflow is a GWorkflowDL representation of a multi merge that invokes C after each invocation of A or B.

Workflow Pattern - Structured Synchronizin... (2)

• Download

This workflow is a GWorkflowDL representation of a structured synchronizing merge that invokes either A or B or A and B and merges to one branch afterwards.
