Simple, Safe & Effective
COBOL to Java / C#
Parallelizing translated Java and C# Batch Programs
Translation COBOL applications to Java or C# opens the door for utilization of today’s cheaper multi-core processors and cloud based deployment.
For online application
, the performance of Java/C# applications has always been easily managed using server-side load balancing techniques.
However batch processes require some additional manual enhancements to allow them benefit from multi-threading/multi-core processors or the cloud.
The work usually involves parallelization of program loops
where most of the execution time is spent.
Parallelization of Batch processes together with use of cloud based deployment will allow each batch process to complete faster through availability of multiple process cores.
Meanwhile the running costs will be reduced
as additional processors may be added (on the cloud) only for the duration of the process.
SoftwareMining Parallization APIs for translated Java / C# code
SoftwareMining now includes a set of APIs within its framework to facilitate cyclic multi-threading
for translated applications through small and limited manual changes.
The facilities provided within the framework includes:
- Start-up options : the framework can automatically launch and manage multiple instances of a batch program
- Advance load and cache for static (no-changing) input data.Havin the data in memory provides much faster access to the data for the launched instances
- Patterns for identification /division of work between launched instances (e.g. process records for clients A-M in thread-1, and N-Z in thread-2)
- Synchronization Barrier - Allows system to wait for completion of all instances before moving to next stage (e.g. writing the data).
- Clean-up on completion.
