Hi, here is my answer to your question.
../sys/setparams was compiled for 4 static threads by the UPC compiler
(upcc) because of the "-T ${NP}" compiler flag in your makefile. But
"../sys/setparams cg S 4" tried to run with only 1 thread because it
didn't use the upcrun command. The thread count mismatch caused the UPC
runtime library to report the error.
Because setparams doesn't need to run in parallel, you may compile it
with a regular C compiler and run it in serial.
You may find the information about building setparams in the makefile
"sys/make.common".
setparams is compiled/linked by $(UCC) which is defined in make.def as
the following:
UCC = upcc -T ${NP} -O -network=mpi -Wc,-g
The quick fix is to use the regular C compiler for building the NPB
utilities. You may try the following in your make.def:
UCC = gcc -g ## or any other compatible C compiler such as icc.
Regards,
Yili
