That said, there are a lot of task that do parallelize well. There's a large market for machines with >5k cores. Often with a significant share of the jobs running on >1k cores. The big HPC sites (weather, energy, defense, research, seismic) have invested the last 3 decades into making parallel algorithms to solve their problems; first with shared memory parallel, but massively parallel has been the name of the game for at least 15 years.
Because your algorithm doesn't scale, does not mean that there is no market for parallel machines. Cray, HP, IBM seem to be making a lot of money selling parallel machines. Sicortex just couldn't make their architecture awesome enough to take sales away from the entrenched players.
Sicortex isn't the only vendor to fail in the HPC space. With or without a low power architecture, it's a hard market to make a lot of money in. It's an easy market to get into, so a lot of people try, but it's not easy to stay profitable, and the investors wanted to lower their risks.
