FIGURE 21 Primary key and foreign key This example shows a basic relationship between two entities After creating the relationship, you specify in its definition any constraints on data manipulation actions on the parent and child entities For example, you can specify that any INSERT into the child entity should fail if there isn t already a parent instance with a matching primary key value Similarly, you could specify that any DELETE statement against the parent entity

Note that here and in the subsections that follow, we import each PyParsing name that we need individually For example:

// functions are not relevant so we do not include the // function bodies extern int neighbor(int); // return the ID for a thread's neighbor extern void do_a_whole_bunch(int); extern void do_more_stuff( ); int main() { int flag[MAX]; //Define an array of flags one per thread int i; for(i=0;i<MAX;i++)flag[i] = 0; #pragma omp parallel shared (flag) { int ID; ID = omp_get_thread_num(); // returns a unique ID for each thread do_a_wholebunch(ID); // Do a whole bunch of work flag[ID] = 1; // signal that this thread has finished its work #pragma omp flush (flag) // make sure all the threads have a chance to // see the updated flag value while (!flag[neighbor(ID)]){ // wait to see if neighbor is done #pragma omp flush(flag) // required to see any changes to flag } do_more_stuff(); // call a function that can't safely start until // the neighbor's work is complete } // end parallel region }

from pyparsing_py3 import (alphanums, alphas, CharsNotIn, Forward, Group, hexnums, OneOrMore, Optional, ParseException, ParseSyntaxException, Suppress, Word, ZeroOrMore)

This avoids using the import * syntax which can pollute our namespace with unwanted names, but at the same time affords us the convenience to write alphanums and Word() rather than pyparsing_py3alphanums and pyparsing_py3Word(), and so on Before we nish this quick introduction to PyParsing and look at the examples in the following subsections, it is worth noting a couple of important ideas relating to how we translate a BNF into a PyParsing parser PyParsing has many prede ned elements that can match common constructs We should always use these elements wherever possible to ensure the best possible performance Also, translating BNFs directly into PyParsing syntax is not always the right approach PyParsing has certain idiomatic ways of handling particular BNF constructs, and we should always follow these to ensure that our parser runs ef ciently Here we ll very brie y review a few of the prede ned elements and idioms One common BNF de nition is where we have an optional item For example:

If we translated this directly into PyParsing we would write:

The thread then waits until its neighbor is finished with do_a_whole_bunch() before moving on to finish its work with a call to do_more_work()

2

optional_item = item | Empty() # WRONG!

This assumes that item is some parser element de ned earlier The Empty() class provides a parser element that can match nothing Although syntactically correct, this goes against the grain of how PyParsing works The correct PyParsing idiom is much simpler and involves using a prede ned element:

while (!flag( neighbor(ID))){ // wait to see if neighbor is done #pragma omp flush(flag) // required to see any changes to flag }

optional_item = Optional(item)

Some BNF statements involve de ning an item in terms of itself For example, to represent a list of variables (perhaps the arguments to a function), we might have the BNF:

fails unless all matching child entries are removed first Table 21 describes the various options that can be set when an action takes place on a parent or child entity Table 21

VAR_LIST ::= VARIABLE | VARIABLE ',' VAR_LIST VARIABLE ::= [a-zA-Z]\w*

The flush operation in OpenMP only affects the thread visible variables for the calling thread If another thread writes a shared variable and forces it to be available to the other threads by using a flush, the thread reading the variable still needs to execute a flush to make sure it picks up the new value Hence, the body of the while loop must include a flush (flag) construct to make sure the thread sees any new values in the flag array As we mentioned earlier, knowing when a flush is needed and when it is not can be challenging In most cases, the flush is built into the synchronization construct But when the standard constructs aren't adequate and custom synchronization is required, placing memory fences in the right locations is essential

At rst sight we might be tempted to translate this directly into PyParsing syntax:

variable = Word(alphas, alphanums) var_list = variable | variable + Suppress(",") + var_list # WRONG!
