Is it possible to use more than 64 threads in APS ?
( When I run a big PEXed circuit with 64 Cores ( manullay setting) SPECTRE gives warning as:-
WARNING (SPECTRE-407): Total number of threads (I251.N_TIA_Q_IN_PLUS_XI1/XI0/XI18/MC4_g) exceeds 64 in disributed APS )
Why this warning is cropping up ?
Hi RF Stuff,
APS for now supports upto 64 cores. However, which MMSIM version are you using? You can find this either from the log file or using -
from the unix command line.
The support for 64 cores has been started from MMSIM11.1.
In reply to Ashish Patni:
My version is sub-version 18.104.22.1687.isr3
In reply to RFStuff:
So, in your version (which is almost latest) as I mentioned in my previous reply, APS supports upto 64 cores.
Do note that this number of cores will only be worthwhile if the circuit is massive (multi-millions of components). Also, you're only likely to see scaling in the transient analysis, and I know you've been using APS with the RF analyses - I doubt very much whether you'd see scalable utilization with 64 cores (I suspect memory would be the limiting factor on a large enough design).
