Varable name with cogid

user82

hi!

i want to start a task on several cogs in parallel and make them use var1,var2 etc

now "cogid" is not recognized if i write "varcogid"

how can i solve this?(hope its not needed on compile time because i wanted to write one PUB for all cogs)

greetings

What about something like this

CON
  ccnt = 4
  
VAR
  long  storage[8]
  long  stack[16*ccnt]

PUB null | idx

  idx := 0
  repeat ccnt
    cognew(method, @stack[16*idx++])

PRI method | private

  private := storage[cogid]

It starts 4 cogs each of which uses a private slot in the storage array.

hmh yes thats good my concept is:

one "master" cog
several worker cods that do exactly the same thing

now every worker cog gets its global variable with number 1-7 where it puts the results that cog0 needs for doing its own work based on the results the other cogs deliver

i could use the bunch of longs for doing this, thank you!

Don't forget: you can also start Spin cogs with parameters. So something like this will also work:

  cognew(method(@var1), @stack1)
  cognew(method(@var2), @stack2)
  codnew(method(@var3), @stack3)
  ...

PUB method(var_addr)

  ...

also good hint, thanks

i will test both methods since its a first test code
