[edit] Description of Defect Classification Scheme

This classification scheme for "errors in MPI" was presented by Jeff Squyres and Jayant DeSouza at the BoF in SC 2005. The defect types have 2 or 3 levels of hierarchy. Detailed descriptions of each defect type were not provided.

[edit] Purpose

Summarize MPI errors

[edit] Entries

Type	Subtypes
Synchronization	Deadlock	Standard
		Timing-dependent
	Data Race	Interface
		Interprocess
Mismatch	Call type
	Arguments
	Length
Resource	Allocation
	Initialization
	Deallocation

[edit] Other Findings and Contexts

Since this scheme was developed to capture MPI errors specifically, it does not capture the items such as Side-effect of Parallelization in Defect Classification Scheme (Mar 06) since it doesn’t directly involve the MPI language itself.
