- Hi...
- In order to accelerate a numerical calculation, I'm trying to put
- small code in the fast on-chip RAM, using
-
- SET processor (order.code := -1)
- MAP logical.processor ONTO processor
-
- and the corresponding /RE option on the occonf.
-
- It works... but don't increases the speed!!!
-
- The small code is a small program that perform 1000000 iterations
- changing only 5 REAL64 variables. This code is put into five transputers
- connected like a ring. Communications take place only 3 times over the
- network.
-
-
-
- What's wrong???
