### VBench
VBENCH is a fork of MOSBENCH but allows running benchmarks inside
VM as well.
## Supported benchmarks:
- Currently, we have included the following benchmarks for evaluation:
- Gmake: Fork intensive, but spends most of the time in the userspace.
- Exim: Crazily stresses `mm`, `fs`, and `process` sub-systems.
- Psearchy: Stresses the interrupt service, used to stress the writer side of the `mmap_rwsem`.
- Metis: Stresses the reader side of the `mmap_sem`.
- Hist: Stresses the reader side of the `mmap_sem`.
## Setup environment
- First compile the relevant benchmarks as follows:
- Exim: `make all-exim`
- Psearchy: `make all-psearchy`
- Metis: `make all-metis`
- Hist: `make all-hist`
- Configure the following variables in the `config.py`:
```python
ROOT = "~/vbench" # Provide the relative path (this is also used in the VM)
CPU_CNTS = 160 # Total number of cores (cores * sockets)
CORES_PER_SOCKET = 10
CPU_STEP = 10 # Numbers of cores to increase until CPU_CNTS in each run
```
- Modify the hostname in the hosts.py. You can set it to `127.0.0.1` and disable sanity check in `mparts/host.py`
- Create multiple `tmpfs` partitions with the following command:
```bash
$ sudo ./mkmounts tmpfs-separate # sudo is mandatory
```
- After this, you can use `config.py` to execute benchmarks.
```bash
$ ./config.py -h
Options:
-h, --help show this help message and exit
-d, --dryrun dry run (default: sanityRun = False)
-t TRIALS, --trials=TRIALS
trials (default: TRY = 1)
-c CORES, --cores=CORES
number of cores for dryrun, default = 80
-n, --profile-nos get numbers using perf stat
-r, --perf-record record all functions
--kvm-record perf record for guest, only works with -r option
--guest-only-record only records the guest, no host side recording
-p, --pin pin all the tasks in qemu process
-l, --lockstats get lock stats
-m, --multivm run two VMs simultaneously
--kvm-stat get the kvm stats if possible (only possible for PVM)
--trace-kvm get the results using trace-cmd
```
### Executing a benchmark
- To run a benchmark, here `exim`, across all cores, execute the following:
```bash
$ ./config.py exim # runs the exim benchmark from core 1 to core 160.
```
- After running the benchmark, results are displayed on the terminal
and are stored in the results folder, which can be used for plotting
by using the `./graph` script.
