4-d Domain-Wall Dirac operator implementation #91

Closed maddyscientist closed 10 years ago

maddyscientist commented 11 years ago

To enable the use of Mobius fermions and the depletion method, we need to implement a 4-d preconditioned domain-wall operator.

Hyung-Jin, can you point me to documention about the depletion method and also the cps source files for the 4-d preconditioner domain-wall operator?

Hi Mike,

Here are some references

The 1st file(LatticeQCD.pdf) is about to the deflation method and 2nd one(4deopc.pdf) is related with 4d even-odd preconditioning method.

Currently, CPS code does not support 4d even-odd preconditioning method officially.

But Taku Izubuchi and Tom Blum made an 4d even-odd preconditioning dslash operator based on CPS code.

You can download it from my google drive.

The address is given as follow.

https://docs.google.com/open?id=0B9HA9nJmJ9FqZGtHWk9JUlIxc0E

To compile this code, you may also need to use GotoBLAS(or OpenBLAS, I recommend this one).

If you need any other information, please let me know.

Many thanks Hyung-Jin
