Sleepsort

efficiently sleeping with (sub-)nanosecond precision and asm threads

Benchmarks

With good numbers and optimized timeouts, sleepsort can achieve similar performance as C’s qsort.

Example using the included array in data.asm:

time ./sort # real 0.008s
time ./csort # real 0.002s

Dependencies

• nasm
• gcc
• make

Usage

$EDITOR data.asm # edit array
$EDITOR config.asm # choose syscall/busyloop strategy
./optim.sh # find optimal sleep timeout
./sort

Usefulness

None
