Description rong li CLA 2010-10-26 01:24:03 EDT 
Build Identifier: 1.0

The latest version of SCI includes new code libsci/privatedata.{cpp,hpp}. This appears to be an attempt at allowing each thread to have its own 'private' data supported through the pthread library. The big problem that this forces a severe constraint on SCIs API. When SCI_Initialize() is called, the private data of the calling thread will be initialized. When the same thread then calls the API, say SCI_Bcast(), it works fine. However, if any other user thread makes the call its private data will not have been initialized. The SCI will then operate on a NULL pointer.

Reproducible: Always
