Facebook porting its PHP engine to ARM

hhvm-logoA post by Facebook on the Hip Hop Virtual Machine blog on Thursday indicated that the team is implementing ARM processor support in its translation engine. This will turn Facebook’s PHP code into 64-bit x86 instructions to execute on compute nodes. The HHVM is Facebook’s fundamental unit for running its mammoth PHP-based social network.

Another clue for Facebook’s shift is a job posting on the company’s site for an ARM server software engineer: “Facebook is seeking an experienced Software Engineer to help us port the world’s best PHP run-time on servers based on ARM processor,” the company wrote. “We aim to evaluate further improving the efficiency of our web tier by porting HipHopVM to new server hardware platforms based on power-efficient ARM”.
