2. © 2003, Hewlett Packard [2] 6-Mar-03 I Was Going To Brag About Marvel… But Jean and Michael beat me to it! So, on to…

3. © 2003, Hewlett Packard [3] 6-Mar-03 What is the Itanium ® Architecture? It’s an architecture –64-bits –Features designed to address silicon-imposed limits Prefetch, Speculation Two loads and a store to each FMAC unit from large, on-die caches It has a number of implementations –Itanium-2 –Madison, Madison++ –Montecito – … Itanium is a trademark of Intel.

4. © 2003, Hewlett Packard [4] 6-Mar-03 What is Itanium? A chip that does a great job on commercial workloads –Record-breaking TPC-C results for large Itanium SMPs –HP expects a successful launch of its Madison-based servers this summer One socket all the way up to 64 sockets HP’s first large servers featuring Itanium A chip that does a great job on cache-friendly HPTC apps –Fastest SPECfp numbers of any microprocessor –95% of peak on Linpack

5. © 2003, Hewlett Packard [5] 6-Mar-03 The Current Implementations Are… They are not cost-effective memory controllers –Apps that beat up the memory system with small, random reads won’t see the performance benefits of the chip. –Some of the causes are due to the chipsets rather than the processors Cost decisions dominate how many sockets share 6.4 GB/s (currently) memory bandwidth They are not priced the same as Pentium ® –The difference is worth it if: Your app can take advantage of very, very large on-die caches Your app needs 64 bit addressing You need large SMPs Pentium is a trademark of Intel.

6. © 2003, Hewlett Packard [6] 6-Mar-03 What It Could Be… If Itanium only achieves its goals of being great for commercial workloads and cache-friendly HPTC, it will be a great success But, the architecture is capable of more –It can be better for non-stride-1 memory bashers Intel is now engaging advanced HPTC types (you know who you are) to look into this Chipsets can also differentiate here –HP is engaged in Research (note the big R) to work on memory, density and system issues

8. © 2003, Hewlett Packard [8] 6-Mar-03 HPUX Scale-Up A wonderful ISV-led market of single systems scaling up to 64 sockets –Scale-out variant available, but focus is on single- system applications Exceeds the revenue of our scale-out business

9. © 2003, Hewlett Packard [9] 6-Mar-03 Linux Scale-Out IA-32: Many relationships with 3 rd parties IA-64: PNNL, followed by others XC: Itanium and IA-32 Linux Scale-Out Product

10. © 2003, Hewlett Packard [10] 6-Mar-03 Lustre Two foci at HP –HPTC is looking to Lustre to be the highly scalable parallel file system for its scale-out systems –HP’s Storage Division expects Lustre to be a key part of its NAS offerings What’s it to you? –A way to separate procurements of storage and computes. –Heterogeneous –Open Source –Scalable as all heck Both for home directories and large, parallel file systems

11. © 2003, Hewlett Packard [11] 6-Mar-03 Godiva DARPA HPCS investigation with HP Labs, HP’s HPTCD group, Rice, and USC ISI Looking at aggressive PIM designs –Both hardware –…and software (esp. programming models) Tidbit: very strong synergies with a future SMP design

12. © 2003, Hewlett Packard [12] 6-Mar-03 HP Labs Linux –Itanium lead an HP Labs member Systems Manageability –UDC: Machine-room provisioning, thermal management, grid access, … MRAM –Non-volatile memory that has disk drive economics, with dramatically improved latency and bandwidth. New HPC group within HP Labs, led by Rob Schreiber –Godiva part of this group’s portfolio
