3
October 3rd 2007 michele michelotto - CCR3 Dual core AMD: Opteron 22xx La serie base consumo costo poco meno di quella a basso consumo La serie ad alto consumo costa come quella normale ma estende il clock
4
October 3rd 2007 michele michelotto - CCR4 4core Barcelona Prezzi doppi allo stesso clock Clock iniziali molto bassi (problemi di resa?)
5
October 3rd 2007 michele michelotto - CCR5 4core Barcelona Prezzo per clock per core Conviene prendere clock bassi e 4core (fino a quando le prestazioni seguono il carico)
6
October 3rd 2007 michele michelotto - CCR6 Prezzi attuali Worker node “alla dozzina” –Conviene prendere macchine con dual processore 4core. 2 GB per core –Non so ancora i prezzi di macchine con Barcelona –Interessanti le twin: due blade in una pizza box 1U

October 3rd 2007 michele michelotto - CCR14 Prossimo Tock Dopo il tick Penryn nel 2009 arriva il tock Nehalem Nuovo raddoppio dei cores Fino a due thread per core Intel Quickpath simile a Amd Hypertransport? Memory controller integrato come Amd

October 3rd 2007 michele michelotto - CCR19 Server
20
October 3rd 2007 michele michelotto - CCR20 desktop Per desktop e workstation Un pc desktop con un 4core produce come un dual dual core (pythia, cms, root)
21
October 3rd 2007 michele michelotto - CCR21 SUN + K10 SUN X4600 M2 8 blade con barcelona Totale 32 cores 256GB DDR2 per chassis 4 alimentatori hotswap 6 slot PCIe 8x Sotto la versione piccola con “solo” 4 processori
22
October 3rd 2007 michele michelotto - CCR22 Futuro amd 2008 Shangai a 45 nm (cache maggiori) 2009 Versione 8 core sempre a 45 nm
23
October 3rd 2007 michele michelotto - CCR23 1H 08 ?
24
October 3rd 2007 michele michelotto - CCR24 Load transactional Le macchine con i nuvoi processori Quad-core continuano a migliorare Piccola flessione del clovertown Invece l’unico dual core comincia a saturare
25
October 3rd 2007 michele michelotto - CCR25 Consumi Notevole il miglioramento del Xeon 5472 vs Xeon 5365 Stesso clock ma passaggio da 65nm a 45nm Barcelona consuma meno ma a 2.0 GHz
26
October 3rd 2007 michele michelotto - CCR26 Perf/watt Barcelona a 65nm rende come lo xeon a 45nm NB in questo particolare benchmark
27
October 3rd 2007 michele michelotto - CCR27 Consumi idle AMD molto parchi in idle
28
October 3rd 2007 michele michelotto - CCR28 AMD preferisce gcc
29
October 3rd 2007 michele michelotto - CCR29
30
October 3rd 2007 michele michelotto - CCR30 Effetti delle cache Nonostante cache maggiori la latenza del 54xx migliorata Impressionante differenza di banda tra 4MB e 64MB. Se la vostra applicazione sta spesso in questa zona vedrete differenze sensibili nelle prestazioni
31
October 3rd 2007 michele michelotto - CCR31 Memoria intel vs amd Tempi di accesso simili A 1GB (occupazione media di programmi HEP) i nuovi AMD hanno risultati migliori Ma i nuovi Xeon 54xx migliorano molto i 53xx
32
October 3rd 2007 michele michelotto - CCR32 Mem intel e amd Dipende dove misuri, quindi dipende dove lavora la tua applicazione

35
October 3rd 2007 michele michelotto - CCR35 Consumo della memoria Gli intel usano memoria FB- DIMM con consumi maggiori
36
October 3rd 2007 michele michelotto - CCR36
37
October 3rd 2007 michele michelotto - CCR37 High K dielectrics Uso di ossido di Afnio nel gate Costante dielettrica maggiore implica minori correnti di leakage

October 3rd 2007 michele michelotto - CCR39 Alimentazione DC XX Nell’UPS converto in continua in parallelo alle batterie Poi riconverto in alternata verso la power distribution unit Entro nel rack in alternata ma nell’alimentatore di nuovo converto in continua E di nuovo nelle diverse correnti continue Poi ci sono delle perdite nei voltage regulator Solo il 48% arriva alla macchina (ventole, dischi, cpu, memoria)

October 3rd 2007 michele michelotto - CCR52 Up to 1 Terabyte of non-volatile DDRRAM in 24U. Unlimited overall capacity Over 3.2 million random I/O requests per second. Over 24 GB/second of random sustainable data bandwidth. Up to 512 physical LUNs. Requires 2,500 watts of power. Up to 8 independent non-volatile solid state disks (SSD) modules. Each SSD module is a RamSan-400, including 128 GB of DDRRAM and up to eight 4-Gbit Fibre Channel connections or four 4x InfiniBand ports.RamSan-400

October 3rd 2007 michele michelotto - CCR54 3.5 inch SSD SimpleTech has released the 256GB 3.5″ SSD and announced 512GB one to come in Q3, this year The drives are called Zeus-IOPS and currently offer the biggest capacity on the market of 3.5 inch SSDs Upon that, the drives are also extremely fast, at 200x, but, unfortunately are very expensive. The 512GB is expected to be priced at about $3,000 when launched and it may get to $1,000 in a few years, but then we will probably have a few terabytes drives. 200x performances of a 15000 rpm drive.
55
October 3rd 2007 michele michelotto - CCR55 640GB disk on PCI PCI EXpress X4 is used. Transfer speed is close to 1GByte/sec. Thus, this 640GB drive above will be read in some 11 minutes ! How long we have waited until HD brake 1TByte limit?
