Article 2136 of dec.notes.technology.dechips: Title: MIPS R10000 @ 200MHz Reply Title: (none) A few days ago I received a note sent to the 'CCT Users Group' asking about the performance of the Cooper & Chyan Specctra Printed Circuit Router. The user also said essentially 'I expect it might be fast on Alpha if it were ported to it'. Several other users wrote follow on notes about Specctra performance, all saying that in their experience it ran the fastest on SGI machines. A user from SGI reiterated that in his experience SGI won all their benchmarks. He gratiously (confidently) sent us the benchmark he has been using and we ran it on several machines we had here. The following is the note I just sent to the CCT user's distribution. Bob Armstrong -------------- Specctra Performance A few days ago, Perry sent out a note asking about 'which box is the fastest'. Clearly this is a moving target, but I gotta admit I was a little dismayed that he didn't seem to know that it ran on Digital's Alpha machines. Lon Tidwell was gracious enough to send us his benchmark and we ran it on a few machines we had here...not necessarily the fastest nor tuned at all for a real benchmark. But we wanted to give you some idea. This benchmark is probably too small for real comparisons. But here are some results (Lon provided the SGI numbers). We included some stats from the Specctra output at the end. bob armstrong Workstations: Type/Model O/S CCT Ver Time (sec) DIGITAL AlphaStation 500 5/500 Digital Unix 4.0 V6.0.0 45 Alpha 21164 500Mhz/2M Cache CPU: Single (Networked) SGI Solid IMPACT 10K SGI IRIS 5.3 V6.0.9 65 R10K 195Mhz / 2M Cache CPU: Single (Networked) Servers: Type/Model O/S CCT Ver Time (sec) DIGITAL Alphaserver 4100 5/533 Digital Unix 4.0 V6.0.0 41 Alpha 21164 533Mhz/??M Cache CPU: Multi (?? installed) DIGITAL Alphaserver 8400 5/300 Digital Unix 3.2 V6.0.0 62 Alpha 21164 300Mhz/2M Cache CPU: Multi (12 installed) ------------------------------------------------------------------------------ #SPECCTRA Version V6.0.3 made 96/01/26 at 18:35:51 #Host 0000f8033174 #ROUTING STATUS <<< ./test.dsn >>> Start Time: Fri Dec 13 12:53:58 1996 Report Time: Fri Dec 13 12:54:39 1996 Nets = 109 Connections = 165 Current Wire = 65 Reroute wires = 65 Completion = 100.00% Unconnections = 0 | ROUTING HISTORY ================================================================ | Pass | Conflicts | | | | | |Red| CPU Time | | Name |No.| Cross| Clear|Fail|Unrte| Vias|XTalk|Len.| % | Pass | Total | |----------+---+------+------+----+-----+-----+-----+----+---+---------+---------| | Route | 1| 820| 37| 0| 0| 119| 0| 0| | 0:00:05| 0:00:05| | Route | 2| 364| 2| 0| 0| 159| 0| 0| 57| 0:00:12| 0:00:17| | Route | 3| 165| 4| 0| 0| 206| 0| 0| 53| 0:00:10| 0:00:27| | Route | 4| 36| 0| 0| 0| 237| 0| 0| 78| 0:00:08| 0:00:35| | Route | 5| 0| 0| 0| 0| 269| 0| 0|100| 0:00:06| 0:00:41|
