Tprint is a printing library for programs running on SW-5 architecture, which is used by the 2017Jun Top#1 supercomputer Sunway-TaihuLight. Currently, the library provides full functional C APIs and limited fortran APIs.
A core group (CG) is a biasc computational element in SW-5 arch.
A CG has 1 MPE (master core) and 64 CPE (co-process core), and athread library is used for parallelism.
However, athread library does not handle the neccessary synchronization for printing,
so the default printf statement will produce unreadable result.
Tprint library provides synchronization to ensure meaningful output. Tprint also provides a variety of functions, including color, selected threads, and 8x8 matrix output format.
see Makefile for how to build it.
Type make run to see C example.
Type make sub_f for fortran example.
#include "tprint.h"- Link your program with
libtprint.a
The usage of APIs is described by the comments in tprint.h.
