Want to calculate Sha1 through Rent supercomputer.

[cml]

Hi beginners,

I want to rent supercomputer for Sha1 calculation ..
i am viewing two computers.. as below ..

first is Titan supercomputer from here .
http://www.olcf.ornl.gov/titan/
here is Titan specification.
Architecture 18,688 AMD Opteron 6274 16-core CPUs
18,688 Nvidia Tesla K20X GPUs
Power 8.2 MW
Operating system Cray Linux Environment
Space 404 m2 (4352 ft2)
Memory 693.5 TiB (584 TiB CPU and 109.5 TiB GPU)
Storage 40 PB, 1.4 TB/s IO Lustre filesystem
Speed 17.59 petaFLOPS (LINPACK)
27 petaFLOPS theoretical peak
First GPU based supercomputer to perform over 10 petaFLOPS

second is Ohio supercomputer center from here.
https://www.osc.edu/
here is specification of Ohio superdomputer

Any one can inform which is best for Sha1 calculation ..
Any one can inform that hashcat can work with above system.

Waiting your good feed back.
Regads.
