    Hello,
We are trying to port UPC/GASNet to a new platform, and are currently 
looking at providing the operations in gasnet/gasnet_atomic_bits.h. I 
read the draft HOWTO posted at 
http://upc-bugs.lbl.gov/bugzilla/show_bug.cgi?id=1607, which was very 
helpful.

However, it seems our platform falls into under the 5c bullet of that 
classification, namely we have an atomic test-and-set operation. The 
suggestion in that document is that a variation of the load-and-clear 
algorithm could be used in this case, but at a quick search I didn't 
find any references to such an algorithm. If anyone can provide any 
further references or guidance on this matter, it would be really helpful.

Thanks,
George
