Parallel Computing Facility at Physics Department, MRU

Recently, we have established an ultimate research facility in physics department. We have successfully accomplished a 10 node parallel computer, it is now fully functional and giving 98-99 % efficiency. All the installed softwares are freely available open source and the operating system is Ubuntu, every computer is quad core so we have a computing power of 40 cores. We can use it for advanced multidisciplinary research.

What is Serial Computing

• Traditionally, software has been written for serial computation
• A problem is broken into a discrete series of instructions
• Instructions are executed sequentially one after another
• Executed on a single processor
• Only one instruction may execute at any moment in time

What is parallel Computing

In the simplest sense, parallel computing is the simultaneous use of multiple compute resources to solve a computational problem:

Benefits of parallel Computing

• A problem is broken into discrete parts that can be solved concurrently
• Each part is further broken down to a series of instructions
• Instructions from each part execute simultaneously on different processors
• An overall control/coordination mechanism is employed
• Execute multiple program instructions at any moment in time;
• Be solved in less time with multiple compute resources than with a single compute resource.

The compute resources are typically:

• A single computer with multiple processors/cores
• An arbitrary number of such computers connected by a network
