Hi, can anyone suggest a good strategy for utilising the most of SMP hardware
when building software from pkgsrc??
I have Sun E450 with 4X 250MHz UltraSparc II CPUs, most of the time the system
is 70% idle, because pkgsrc tends to use mainly 1 CPU.
Fixing all Makefiles to support -j > 1 seems quite unreasonable, I guess the
best solution would be to have a multithreaded compiler, which distributes
workload to a specified number of threads, i.e.:
cc -xO3 -xtarget=ultra -xthr=4 some_file.c
-xthr=4 would tell compiler to spawn up to 4 threads when invoked
I wonder if there are such compilers out there...
