    Dear list,

if I understand it correctly, the UPC standard does not provided any 
atomicity guarantees for load/store operations to the shared memory. Is 
there any way for implementing atomic set function for double values?

BUPC provides the bupc_atomic* extensions which could be used for 
storing a 64 bit double value atomically. However, as I understand it 
these functions do not work if another thread accesses the memory region 
with upc_memget() instead of bupc_atomicX_read(), right?

Thanks,
Dorian
