CS-2 tutorial at Durham HPC Days
CSL is used to build SWs to communicate and program the device
CSL compiled using csls command and generates .elf excuteable file
in CSL:
bulitins:
task:
loyal file:
// Color used by memcpy for RPC mechanism
const LAUNCH: color = @get_color(8);
// Import memcpy layout module for 1 x 1 grid of PEs
// This module defines parameters passed to program on the single PE
const memcpy = @import_module("<memcpy/get_params>", .{
.width = 1,
.height = 1,
.LAUNCH = LAUNCH
});
layout {
// Use just one 1 PE (columns=1, rows=1)
@set_rectangle(1, 1);
// The lone PE in this program should execute the code in "pe_program.csl"
// We pass memcpy parameters as a parameter to the program. Note that
// memcpy parameters are parameterized by the PE's column number.
@set_tile_code(0, 0, "pe_program.csl", .{ .memcpy_params = memcpy.get_params(0) });
// Export host-callable device function
@export_name("init_and_compute", fn()void);
