As your complete electro-mechanical engineering design services partner, Concurrent Design can provide you with: funding assistance (by providing professional engineering project plans for your business plan), new product development strategy, conceptual designs, engineering analysis, mechanical engineering services, design for manufacturability, electrical engineering services with associated software, all detailed design and manufacturing documentation requirements, prototyping for your commercial or industrial product design and fabrication of your custom machine design / custom manufacturing tool design. As part of manufacturing scale-up, we can provide existing process improvement optimization including manufacturing plant layout, turnkey automation systems with full or virtual instrumentation, and full test equipment capabilities. Concurrent Design can help take your invention from idea through research, engineering, documentation and manufacture.
Suppose balance = 500 , and two concurrent threads make the calls withdraw(300) and withdraw(350) . If line 3 in both operations executes before line 5 both operations will find that balance >= withdrawal evaluates to true , and execution will proceed to subtracting the withdrawal amount. However, since both processes perform their withdrawals, the total amount withdrawn will end up being more than the original balance. These sorts of problems with shared resources need the use of concurrency control , or non-blocking algorithms . [ citation needed ]
