[edit] Purpose

Update the scheme in Defect Classification Scheme (Jan 06)

[edit] Entries

Type	Sub-type	Definition
Algorithm	---	Logical error
Side-effect of Parallelization	I/O Defects	Serial constructs can cause correctness and performance defects when accessed in parallel contexts.
	Defects with Random Functions
Use of Language Features	---	Erroneous use of parallel language features
Space Decomposition	---	Incorrect mapping between the problem space and the problem memory space
Synchronization	Deadlock	Incorrect/unnecessary synchronization
	Race
Performance	Load Balancing	Scalability problem because processors are not working in parallel
	Scheduling
