#Define parsec code

The ROI is the part of the code that should be used for benchmarking and analysis. This function is executed exactly once, immediately after the Region-of-Interest (ROI) is left. The logical counterpart of this function is _parsec_roi_end. This function is executed exactly once, just before the Region-of-Interest (ROI) is entered. Its logical counterpart is _parsec_bench_begin. This function is executed exactly once, just before the program ends. Its logical counterpart is _parsec_bench_end. This function is executed exactly once, as soon as the program starts. Parameters: _bench Unique workload identifier.

The benchmark passes it to _parsec_bench_begin() at the beginning of its execution. Guard macro to prevent multiple inclusions.Įach workload has exactly one unique identifier in this enumeration. To change the behavior of the PARSEC hooks, look at files config.h and hooks.c. Share these Notes with your friends Prev Next > You can check our 5-step learning process. If we ran this parser we would either end. So the two together gives us a parser that takes 1 or more digits. Earth circles the Sun, making one complete orbit per year. many1 is a parser combinator it takes a parser p and transforms it into a parser that parses 1 or more occurances of p. A: A parsec, or parallax second, is defined as 3.26 light-years because of how it is measured. digit is a parser that matches a single digit character (0-9).

If you modify this file, you might also have to update all benchmark programs of the PARSEC distribution. parsec(distance at which average radius of earth’s orbits subtends an angle of 1 arc second) pc. The heart of our parser is in many1 digit. Pthread_create(t, NULL, worker_func, NULL) Some preliminary functionality is already provided which can be enabled or disabled in the config.h file of the hooks library before compilation.īenchmark programs typically call the hook functions as follows: These functions can be used to plug in any type of functionality at the designated locations of each PARSEC workload. It is now defined as exactly 149,597,870.7 kilometers. Estimates of this distance have varied over time. Parallax can be used for distances of upto 10,000 lightyears / 3 kpc. An astronomical unit is the average distance between the Earth and the Sun. 1 AU is equal to 1.4960x10 11 meters and 1 parsec is equal to 3.26 light years, which makes Centauri 4.405 light years away. It is exactly 648,000/ astronomical units, or approximately 30.9 trillion kilometers. If enabled each PARSEC workloads calls the hooks library functions at certain predetermined locations. A parsec is a unit of distance used in astronomy. This file specifies the PARSEC Hooks Instrumentation API. The specification of the PARSEC Hooks Instrumentation API.

Section: PARSEC Hooks Instrumentation API (3) Astronomers and scientists doing research on outer space use parsec and light years.Manpage of include/hooks.h include/hooks.h These units cannot be used in our day-to-day life because on earth, the distances we deal with are in metres, kilometres, and parsec and light years are very much larger than kilometres. Note: Units like parsec and light years are very large units of length. One parsec is about 30 trillion kilometers, or just over. One light year the distance that light travels in one year. Bottom line: One parsec is defined as the distance to a star that shifts by one arcsecond from one side of Earth’s orbit to the other. One parsec is the distance, which subtends a parallax angle of one arcsecond. The distances between planets and stars in outer space are measured in these units. Hint: Parsecond and light years are units of length.
