Roland asked about overlap of communication and computation during SYNC
statements.
* communication buffers are all data between pairs of processors
* multi-threaded MPI may be required to keep a thread inside of MPI all
the time for systems where MPI does no work unless a caller is inside
its code. Could use self-compiled OpenMPI on blue waters or
multi-threaded Cray MPI.
* suggestions to use mpi trace
* stand-alone test may be best
* need to determine that there is actually a benefit of this overlap
Piraha parser:
* currently stop parsing a CCL file at the first CCL syntax error but
will parse multiple files for errors.
* since syntax errors in piraha include things like mis-spelling
CCTK_REAL Roland thinks that aborting at syntax errors is bad also
since typically one will modify only a single CCL files when eg
working on a thorn
* this is however larger than the original intent of the ticket, which
was about some specific files not parsing
* Roland will provide a set of ccl files that should parse but do not
parse
testsuite problems:
* see issues on Nebula Haswel
* see issues on Roland's laptop Kaby Lake
* see issues on Ian's laptop/workstation (Kaby lake)
Workshop this year:
* no date set yet
Yours,
Roland
