With some handwaving it could be about $82.5K (computation spread over 1 year) or $125K (computation done in 1 month).

  total cost was 35 CPU years (Intel Nehalem, 4-core, 2.8GHz)
  1 EC2 compute unit is about 1 GHz Xeon
  let's assume 1 Google unit = 12 EC2 units (3x4 cores)
  High-CPU Extra Large instance = 20 EC2 units

  35*12 = 420 EC2 unit years = 5040 EC2 unit months
  =  21 HiCPU XL instances for 1 year
  = 252 HiCPU XL instances for 1 month
Putting this into AWS calculator [1] yields:

   $82,491.36 (21 HiCPU XL reserved instances for 1 year)
  $125,435.52 (252 HiCPU XL on-demand instances for 1 month)

Edit: It could be actually a bit more, Nehalems seem to be faster than my first estimate.

Plugging in EC2 computing unit comparison from Cluster Compute instance (which has 2x quadcore Nehalem), 1 Google unit can be 16.75 EC2 units.

This gives:

  $114K for 1 year of 29 reserved HiCPU XL instances
  $166K for 1 year of 18 reserved cluster compute instances

  $173K for 1 month of 348 on-demand HiCPU XL instances
  $246K for 1 month of 210 on-demand cluster compute instances

Edit2: Dedicated server hosting would be much cheaper. For example, from Hetzner [2] it would cost just about 26K EUR (= $34K) to rent 35 dedicated quadcore Nehalem servers for 1 year.
