config.mk

## Note: as a convenience hack, this file is included in Makefiles,
##       AND in bash scripts, to set some variables.
##       So, don't write anything that isn't valid in both make AND bash.

## Set the desired maximum thread count (maxthreads),
## an upper bound on the maximum thread count that is a power of 2 (maxthreads_powerof2),
## the number of threads to increment by in the graphs produced by experiments (threadincrement),
## and the CPU frequency in GHz (cpu_freq_ghz) used for timing measurements with RDTSC.
## Be sure that maxthreads_powerof2 is based on maxthreads + 1 to ensure that the bundle
## entry reclamation thread is included in the calculation.
## Then, configure the thread pinning/binding policy (see README.txt.old)
## Blank means no thread pinning. (Threads can run wherever they want.)

# The following is used by the benchmarks to find the allocator to be used by the various 
# components. If it is blank, then the default system alloctor will be used. Note that 
# when setting the path, it must have the same relative path to the `runscript.sh`
# scripts in the `microbench` and `macrobench` directories, since that is where it is used.
