Compiling Intel FFTW3 and FFTW2 Interface Wrapper Library

FFTW3 wrappers to Intel MKL are delivered both in Intel MKL and as source code which can be compiled to build to build standalone wrapper library with exactly the same functionality. The source code for the wrappers, makefiles are found .....\interfaces\fftw3xc subdirectory in the Intel MKL Directory

Intel FFTW3 Interface Wrapper Library. Do the same for fftw3xc and fftw3xf

# cd $MKLROOT
# cd interfaces/fftw3xc
# make libintel  INSTALL_DIR=$MKLROOT/lib/intel64

Once Compiled, the libraries are kept $MKLROOT/lib/intel64  


Intel FFTW2 Interface Wrapper Library. Do the same for fftw2xc and fftw2xf

# cd $MKLROOT
# cd interfaces/fftw2xc
# make libintel  PRECISION=MKL_DOUBLE
# make libintel  PRECISION=MKL_SINGLE

Once Compiled, the libraries are kept $MKLROOT/lib/intel64

Configuring MATLAB FlexNet License Manager to reserve licenses

Step 1: To setup an option file in the Flexlm

https://www.mathworks.com/matlabcentral/answers/100865-is-there-a-way-to-administer-flexnet-based-licenses-how-do-i-create-an-options-file


Step 2: Create an mlm.opt file

RESERVE 1 MATLAB:asset_info=111111 USER user1

where user1 is the username

Step 3: Restart the license server to take effect

Configuring 2 Gateways on the same Linux Box permanently

Suppose you have 2 network on a PC says
192.168.1.5/24 (eth0 - Private Network)
172.16.10.4/24 (eth1 - Public Network)

Let's assume the 172.16.10.254 is the Default Gateway for 172.16.10.0 network. If there is a router at 192.168.1.254 for the internal network and you wish to connect to other networks says 192.168.5.0 192.168.6.0 and 192.168.7.0 networks. You will need to add "static routes" to these networks

route add -net 192.168.5.0 netmask 255.255.255.0 gw 192.168.1.254
route add -net 192.168.6.0 netmask 255.255.255.0 gw 192.168.1.254
route add -net 192.168.7.0 netmask 255.255.255.0 gw 192.168.1.254

To make the setting permanent, edit /etc/sysconfig/network-scripts/route-eth0

192.168.5.0/24 via 192.168.1.154 dev eth0 
192.168.6.0/24 via 192.168.1.154 dev eth0 
192.168.7.0/24 via 192.168.1.154 dev eth0 

To check the setting is ok

# ip route show
