You can simulate parallel jobs using multi-instance server jobs, and/or using Link Partitioner stages within a server jobs.

Read about these techniques in the Server Job Developer's Guide.
With multi-instance jobs you will need to implement a technique for splitting your data over the available instances. For example, where the source is a database table, use a parameterized WHERE clause to specify separate subsets of rows for separate instances.
The Link Partitioner stage does the same kind of thing within a job; input rows are split using a partitioning algorithm that you specify, onto separate output links.
