Can anyone recommend a laptop for SAS 9.4, giant files?

Hello,

I am running SAS version 9.4 for Windows.  I frequently have to import and manipulate giant (~13 GB) files from the state, and each proc can takes hours to run.  And the data sets just keep getting bigger!

My work has offered to purchase a more appropriate laptop for me, and I'm wondering if anyone out there has found a laptop that they would recommend for my situation.

Laptop? Maybe a desktop would be better

But you want as much memory and as fast of a CPU as you can buy.

Sorry - should have been more specific.

1. I'm mobile so a desktop worn't work, unfortunately.

2. I'll definitely try to get the most RAM and a fast CPU.  But is there a specific CPU (for instance) that is a must have?

3. I'm also wondering if there's a specific brand/model that people like (EX: Dell Inspiron, Lenovo thinkpad, etc).

To me, the brand is irrelevant. To me, the proper hardware is what you want to look for. Also, in my experience, you may want to purchase a custom configured computer instead of one of the standard models that manufacturers offer.

Get the fastest CPU that your company will purchase for you. There are many internet websites that compare the relative speed of different CPUs according to various criteria.

Get 32MB of memory (or more if the computer motherboard will support it). And it is mandatory that you get a 64 bit operating system.

I would recommend SSD disk too since SAS is I/O bound.

Just to add, multi-core processor would help, and Solid State Hard Drive.  Onboard graphics is probably a good idea too, whilst proper graphics card is nice, they are power hungry and you don't want to be charging every hour or so.

Can't we use SAS 9.4 in 32 bit OS?

The first release of 9.4 had support for 32bit.  However that's not really the point.  For any system with more than 4gb of ram, you need to have a 64bit system to take advantage of that memory.  So if your running 32bit, 4gb and 32gb memory will run the same speed as on the first 4gb is used.

13 GB doesn't sound giant to me.

If your PROCs takes hours:

  • Optimize your code
  • Use a server instead, which you can control via Enterprise Guide or SAS Studio

-64 bit, no question at all. 32 bit is stone age right now, because the CPU can't address enough RAM to cache big datasets.

-speed is not such a big thing, my venerable p520 runs with two 1.6 GHz cores and will probably run circles around your new laptop anyway, because of the SAN infrastructure (twin PCIe buses, twin 4Gbit FC, HDS storage)

-SSD, SSD, SSD. Eliminates 90% of I/O problems, because it does away with the latencies common on mechanical drives.

And evaluate your import process on all stages with the proper tools. The best Notebook/PC won't help you if you sit behind a slow firewall or are connected to a 100 Mbit switch or 56 Mbit WLAN.

Typical, you wait ages for one and two turn up:

"twin PCIe buses"
