WHY HSA IS INVALUABLE |

The Fabric Engine Case PAUL DOYLE

A high-performance,

multithreaded computational

engine

Easy to use

Integrates with simple, dynamic

languages (Python, JS)

Uses Fabric’s own high-level

language (KL) for performance

sensitive algorithms

Yields performance comparable

to / better than multithreaded

C++

WHY HSA IS INVALUABLE |

The Fabric Engine Case

Makes

high-performance

computing highly

accessible

Engine Case

WHY HSA IS INVALUABLE | The Fabric

Engine Case

Without HSA, extending Fabric to run on GPU

would mean:

Restricting Fabric’s KL language to mark which

language features can or cannot be used when

code is intended to run on GPU

Extending Fabric to expose memory management

interfaces to copy to and from GPU memory

Putting the burden on the user to minimize those

copies

(also, understanding the intricacies of every

platform)

On GPU, without HSA,

Makes

high-performance

computing

highly accessible

… misses the point.

WHY HSA IS INVALUABLE | The Fabric

Engine Case

With HSA,

Makes

high-performance computing

highly accessible:

CPU functions can be called from

code running on GPU;

The user does not worry about

where memory location;

Fabric Engine still compiles to

LLVM bytecode
