Parallel Three-Dimensional Fast Fourier Transforms 2.2 (Default branch)
Parallel Three-Dimensional Fast FourierTransforms, dubbed P3DFFT, is a library forcomputing 3D FFTs using 2D (pencil) decomposition.It is written using Fortran with MPI, and is tunedto work on multiple single-CPU systems (up to32768 of them). It is built to leveragehigh-performance serial 1D FFT libraries, such asFFTW or ESSL.License: Public DomainChanges:
This version provides accurate treatment of the 0 and N/2 modes in the complex sequence in Fourier space.Image

SPIF(4) 						   BSD Kernel Interfaces Manual 						   SPIF(4)

NAME

     spif -- SBus (spiffy) Serial/Parallel Interface

SYNOPSIS

     spif* at sbus? slot ? offset ?		    (sun4c/sun4m/sun4u)
     stty* at spif?				    (sun4c/sun4m/sun4u)
     sbpp* at spif?				    (sun4c/sun4m/sun4u)

DESCRIPTION

     The spif driver provides support for the Sun Serial/Parallel Interface card (Sun part number 501-1931), which is based on the Cirrus Logic
     CD180 octal serial controller and the Cirrus Logic PPC2 parallel port controller.

     The device minor numbers for this driver are encoded as follows:

	 +---+---+---+---+---+---+---+---+
	 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
	 +---+---+---+---+---+---+---+---+
	   |   |   |   |   |   |   |   |
	   |   |   |   |   |   +---+---+---> port number
	   |   |   |   |   |
	   |   |   |   |   +---------------> unused
	   |   |   |   |
	   |   |   |   +-------------------> dial-out (on tty ports)
	   |   |   |
	   |   |   +-----------------------> unused
	   |   |
	   +---+---------------------------> card number

     Up to four cards are supported in the system.

     Each of the serial ports has an 8 byte FIFO for receive and transmit as well as automatic hardware (RTS/CTS) flow control.

FILES

     /dev/ttyS[0123][0-7]  Serial ports
     /dev/bppS[0-3]	   Parallel ports

DIAGNOSTICS

     spif%d: ccr timeout  A timeout occurred while writing to one of the CD180 registers.

     stty%d-%d: ring overflow  Incoming characters were discarded because the application in control of the device did not read the input fast
     enough.

SEE ALSO

     intro(4), sbus(4), tty(4)

HISTORY

     The spif adapter was first supported in OpenBSD 2.5.  The driver was ported to NetBSD 3.0.

AUTHORS

     The driver was written by Jason Wright <jason@thought.net>, and is heavily based on the magma(4) driver written by Iain Hibbert.

TODO

     The parallel port is not supported yet.

     Dial-out (cua) devices are not yet supported.
