Serine Hydroxymethyltransferase
Serine hydroxymethyltransferase (SHMT) is a pyridoxal phosphate (PLP) (Vitamin B6) dependent enzyme () which plays an important role in cellular one-carbon pathways by catalyzing the reversible, simultaneous conversions of L-serine to glycine and tetrahydrofolate (THF) to 5,10-Methylenetetrahydrofolate (5,10-CH2-THF). This reaction provides the largest part of the one-carbon units available to the cell. Structure The structure of the SHMT monomer is similar across prokaryotes and eukaryotes, but whereas the active enzyme is a dimer in prokaryotes, the enzyme exists as a tetramer in eukaryotic cells, though the evolutionary basis for this difference in structure is unknown. However, the evolutionary path taken by SHMT going from prokaryotic dimeric form to the eukaryotic tetrameric form can be easily seen as a sort of doubling event. In other words, the eukaryotic SHMT tetramer resembles two prokaryotic dimers that have packed together, forming what has been described as a †...

Simultaneous And Heterogeneous Multithreading
Simultaneous and heterogeneous multithreading (SHMT) is a software framework that takes advantage of heterogeneous computing systems that contain a mixture of central processing units (CPUs), graphics processing units (GPUs), and special purpose machine learning hardware, for example Tensor Processing Units (TPUs). Each component processes information differently. Often data has to move among processors, which can create bottlenecks, with one processor starving while waiting on another to finish. Architecture The system defines virtual processors and virtual operations (VOPs). VOPs decompose into one or more high-level operations (HLOPs). It then distributes the operations across the processors. The runtime system then dynamically maps virtual processors to physical processors, assessing resource availability in order to keep all the processors busy. The scheduler employs a light-weight, quality-aware work-stealing (QAWS) policy. Conventional runtimes use assign one proces ...
