Hi again,
I came across
"Only if X10_STATIC_THREADS=1 X10_NTHREADS=1 and
X10_NUM_IMMEDIATE_THREADS=0 will we use single-threaded MPI modes."
on one of the pages dedicated to X10.
I now initialized the variables and I'm not anymore facing the error that
provided and requested threading levels do not match.
However, my code uses Clocks for synchronization and I get runtime error
*ClockUseException: Clocks are not compatible
with static threads. *
I guess that I've hit the wall now and can't proceed in this direction.
Or is there a possible workaround to make Clocks work in mpi thread
serialized setting ?
Thank you,
Marina
