NMVeOF setup scripts
#!/bin/bash
# Adapted from https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/managing_storage_devices/configuring-nvme-over-fabrics-using-nvme-rdma_managing-storage-devices
# Exports an NVMe device over Fabrics so that it can be used by remote hosts.
#
# Usage: nvmeof_controller.sh DEVICE SERVER_IP SERVER_PORT TRANSPORT SUBSYSTEM_NAME NAMESPACE PORT
# Example: nvmeof_controller.sh /dev/nvme1n1 192.168.0.100 4420 tcp my_nvme 10 1
#
# Now you can import the device on a remote host.

kig / fast_read.c
Created November 10, 2022 13:16
File read speed optimization tool
/*
What's the fastest way to read a file?
fast_read is a program that reads a file into memory using multiple parallel threads
with a stochastic hill climb optimizer to find the fastest thread count and block size.
Example run (note the effect of page cache, read is basically memcpy after that point):
$ ./fast_read iotest_6G.dat
Opening file iotest_6G.dat for reading
Reading 6442450944 bytes

# Nano config file for minimalistic space-saving layout. Good for e.g. Termux.
# Turns line numbers on, hides help and other things.
# Multifile support on by default.
# Screws with the key bindings to make them more "standard"

# Close file is Ctrl-Q
# Open file is Ctrl-O
# Save As is Alt-S
# Cut/Copy/Paste are Ctrl-X/C/V
