Hi,

I remember using 'global' in the procedure as a global parameter,

however, it's not working...

In my previous posts I discussed the basic difference between parallel programming and single threaded programming. I also showed how controlling access to shared variables can be used to solve some of those problems. For this post, I am going to discuss more difficulties of writing good parallel algorithms.

Here are some definitions used in this post:

• scale: the ability of a program to get faster as more cores are available
• load balancing: how effectively work is distributed over the available cores
• coarse grained parallelism: parallelizing routines at a high level
• fine grained parallelism: parallelizing routines at a low level

Consider the following example

Code to create a maplet that generates unique random numbers from a sample space could look like:

Hi,

I got something like:

t:=NULL:

for i to nops(S) do

...

...

temp2:=(temp)^(-1) mod t[i]:

...

...

od:

the problem is that since I have assigned t:=NULL

for i=1

there is a problem to run

temp2:=(temp)^(-1) mod t[i]:
 

it becomes

temp2:=(temp)^(-1) mod t[1]:

at that time 't' is actually a number , just a single value, so it cant have subscript.

how do I solve that problem?

Hi,

I am writing an procedure in which has the following:

print( array(  [['p', 'q' , 'e', 'd'],
          seq([p[k],q[k],e[k],d[k]],k=1..nops(M1) )       ]));

that 'p','q','e' and 'd' all have been used within the procedure.

The "print", in the first line     "['p', 'q' , 'e', 'd']" , I would like them to display as texts, how should do that?

Thanks.

Hi,

I can generate 1 random number  by

rand(10^20)():

how can i get, say 6 distinct random numbers in the scacle of 10^20 as well?

Thanks.

How do i print numbers upto 100 that are not multiples of x,y,z?
 

I would be very gratefull for any help
 

Thanks
