Fun monday morning benchmarking

Running NCBI BLAST on the JackRabbit we are preparing for shipment. Used the nt database from last july (21 GB in size, 5+M sequences). Our a. thaliana had 1164 sequences, and about 500k letters.
Took 8m 44s to BLAST these sequences against this database. This means about 2.1838e+13 cell updates per second. This is the product of the number of letters in the database and the sequence under test divided by the total wall clock time. As these are 3.2 GHz CPUs, the cycle time per unit is about 0.3 ns. We get about 3.2E+9 cycles per core per second. With 8 cores, this means something closer to 2.5E+10 cycles per second. So, if these benchmarks are meaningful, that means we are getting pretty close to 850 cell updates per processor cycle.

Its up! [our online store]

Took us long enough… Now you can buy your JackRabbit high performance storage systems online. Just click here … Not everything is on the store, but we are moving to get the items up quickly. Nothing quite like buying Gigabytes/s while wearing bunny slippers …

Our customers are not crash dummies …

… and we don’t treat them like such. This is the gist of a conversation we had over the weekend. A JackRabbit unit running Centos 5.2 going out to a customer in the financial services space, required firmware updates for some of its components. It would have been simply too easy for us to do what many of our competitors do, and ship them a firmware/driver update on a CD or USB stick, or point them to a login for downloading the bits. Leave them the pain of doing this.

multiple job opportunities

OT to our usual fare. The day job has a few possible openings for high performance computing technical types. Positions would be in Michigan, and one would have some extended travel. Please contact me if you would like to talk.

Rackable buys TerraScale and now dumps TerraScale

TerraScale were an innovative bunch that developed some interesting technologies around the xfs file system, and made it scale in a cluster. Some time ago, Rackable bought them.
Now it appears that Rackable is pulling back from this market, and is putting TerraScale … er … RapidScale on the auction block.
Ok, its not quite like this … they have engaged a financial advisor to “seek strategic alternatives” for the group. This is usually corporate-speak for “we don’t want to be in this business any more, and will sell the IP, the group, and the brand to someone … if we don’t get what we are looking for, we will just shutter it.”
