/* Simple multi-threaded I/O benchmark program. * Copyright (C) Michael Tokarev, mjt@tls.msk.ru * Public domain. * * To compile: * gcc -o iot iot.c -lpthread * To run: * Either with disk device or with pre-existing file. * ./iot [options] filename * Filename is the file or device to test on. * By default it uses 8Kb I/O blocks and does sequential read test * until interrupted. * To indicate when to stop: * -t sec - run for this many seconds, say, 30, to eliminate random * noise. * -i num - perform this many I/O operations * To indicate R/W mode: * -wn, -Wn, -rn, -Rn -- * perform linear or random write (note: all data will be lost!), * or linear or random read, using given number of threads (n). * I/O modes: * -s - syncronous write (O_SYNC) * -d - direct I/O (O_DIRECT) * -b bs - block size in bytes * And finally: * -h - display usage. * Example: * ./iot -t30 -W4 -R4 -d -b8192 /dev/sdb * perform random read/write test (4 readers and 4 writers) * for 30 seconds using direct I/O and block size of 8Kb. * * Note: for small blocksize (<64Kb at least) and using direct random I/O, * nowadays drives sometimes gives transfer rates below 1Mb/sec - this is * expectable, don't be afraid of so low numbers. The reason is simple: * in order to access a given block of data, a disk drive has to seek to the * right track (average seek time) and wait for the right sector to be near * the head (rotation latency). Sum up the two, and divide 1 sec to the * result -- you'll have max number of requests/sec a drive can perform, * not counting the actual data transfer (which reduces this number further). * With, say, 5ms seek time + rotation latency, we'll have 200 requests/sec, * which, with 4Kb request size, will be about 800Kb/sec - which is below * 1Mb/sec, not counting the actual transfer... * */ #define _GNU_SOURCE #define _BSD_SOURCE #define _LARGEFILE_SOURCE #define _FILE_OFFSET_BITS 64 //#define USE_DEV_URANDOM /* was not a good idea */ #include <sys/types.h> #include <unistd.h> #include <fcntl.h> #include <errno.h> #include <stdlib.h> #include <stdio.h> #include <sys/time.h> #include <sys/ioctl.h> #include <signal.h> #include <pthread.h> #include <string.h> #ifndef BLKGETSIZE64 #define BLKGETSIZE64 _IOR(0x12,114,size_t) /* linux-specific. return device size in bytes (u64 *arg) */ #endif static void edie(const char *what) { fprintf(stderr, "%s: %m \n", what); exit(1); } #ifdef USE_DEV_URANDOM static int randfd; #endif static int oflags; // open flags static char *fn; // filename static unsigned bs = 8192; // block size static unsigned bc; // block count (device size in blocks) static unsigned bm; // blocks to do #define MFrnd 1 #define MFwrt 2 #define LinRd 0 #define RndRd MFrnd #define LinWr MFwrt #define RndWr (MFrnd|MFwrt) struct state { int fd; char *buf; unsigned ioc; // I/O count int (*workfn)(struct state *, unsigned blocknr); unsigned (*posfn)(struct state *s); unsigned opi; // operation index unsigned i; // curidx double stime; // start time unsigned bn; // current block number for linear i/o }; static unsigned int alternate; static unsigned tioc; // total i/o count static struct state *states; static unsigned nt[4]; static unsigned ntt; static volatile unsigned running; static const char *const ion[4] = { "LinRd", "RndRd", "LinWr", "RndWr" }; static pthread_mutex_t rnmtx = PTHREAD_MUTEX_INITIALIZER; static pthread_cond_t rncond = PTHREAD_COND_INITIALIZER; static double curtime(void) { struct timeval tv; gettimeofday(&tv, NULL); return tv.tv_sec + tv.tv_usec / 1000000.0; } static unsigned randpos(struct state *s) { unsigned n; #ifdef USE_DEV_URANDOM read(randfd, &n, sizeof(n)); #else n = lrand48(); #endif s = s; if(alternate == 1) { if(n > bc/2) { return bc-1; } else { return 0; } } return n % bc; } static unsigned linpos(struct state *s) { if (s->bn >= bc) s->bn = 0; return s->bn++; } static int wwriter(struct state *s, unsigned b) { return pwrite(s->fd, s->buf, bs, (off_t)b * bs); } static int wreader(struct state *s, unsigned b) { return pread(s->fd, s->buf, bs, (off_t)b * bs); } static void pst(FILE *f) { double ct = curtime(); double r[4] = { 0, 0, 0, 0 }; unsigned c[4] = { 0, 0, 0, 0 }; unsigned i; double d; for(i = 0; i < ntt; ++i) { d = ct - states[i].stime; r[states[i].opi] += states[i].ioc / d; c[states[i].opi] += states[i].ioc; } #if 1 for(i = 0; i < 4; ++i) if (c[i]) fprintf(f, " %s %u %.2f", ion[i], c[i], r[i] * bs / 1024 / 1024); #endif } static void incc() { if (!(++tioc % 1000)) pthread_cond_signal(&rncond); } static void decnr() { pthread_mutex_lock(&rnmtx); --running; pthread_mutex_unlock(&rnmtx); pthread_cond_broadcast(&rncond); } static volatile int term; void *worker(void *arg) { struct state *s = arg; s->workfn = s->opi & MFwrt ? wwriter : wreader; s->posfn = s->opi & MFrnd ? randpos : linpos; s->fd = open(fn, (s->opi & MFwrt ?
