News for Package 'gpuR'

Version 2.0.0

• API Changes:

  • deviceType, gpuInfo, cpuInfo not longer accepts 'platform_idx' parameter as OpenCL contexts cannot contain more than one platform.

• New Features:

  • Added functionality to create custom OpenCL functions from user provided kernels

  • Added 'synchronize' function to assure completion of device calls (necessary for benchmarking)

  • Added determinant function (det)

  • Allow for gpuR object - base object interaction (e.g. vclMatrix * matrix)

  • Added ‘inplace' function for ’inplace' operations. These operations include '+', '-', '*', '/', 'sin', 'asin', 'sinh', 'cos', 'acos', 'cosh', 'tan', 'atan', 'tanh'.

  • Added 'sqrt', 'sum', 'sign','pmin', and 'pmax' functions

  • Methods to pass two gpuR matrix objects to 'cov'

  • Added 'norm' method

  • Added gpuRmatrix/gpuRvector Arith '+','-' methods

• Bug Fixes:

  • Fixed incorrect device info when using different contexts

  • Fixed Integer Matrix Multiplication

  • All OpenCL devices will be initialized on startup (previous version occasionally would omit some devices)

• Features in Progress:

  • Parallel GPU functionality

  • Implementing 'complex' data type

  • Additional indexing functionality

  • Additional correlation methods

  • Additional gpuR - 'base R' methods

  • gpu-vcl object methods

Version 1.2.0

• New Features:

  • Automatically detect available SDK on install if available

  • Simplified installation to build OpenCL ICD when no SDK installed (thanks Yixuan Qui)

  • Control over individual OpenCL contexts to allow user to choose device to use

  • Added as.* methods for vclMatrix/Vector and gpuMatrix/Vector objects

  • Added str method for matrix objects

  • Added length method for matrix objects

  • Added solve method for square vclMatrix objects

  • Added QR-decompsition, SVD, Cholesky for square gpuMatrix/vclMatrix objects

  • Added diag and diag<- method for matix objects

  • Added colnames and colnames<- methods

• Features in Progress:

  • 'device type' checks (i.e. deal with CPU & GPU objects), perhaps detect type from object?

  • Parallel GPU functionality

  • In-place operations

  • Accept custom OpenCL kernels

Version 1.1.2

• New Features:

  • fixed major bugs with cbind/rbind and deepcopy reflecting new class architectures

• Features in Progress:

  • Additional matrix functions (QR-decompsition, SVD, Cholesky, solve)

  • 'device type' checks (i.e. deal with CPU & GPU objects), perhaps detect type from object?

  • Control over OpenCL contexts for mutliple GPUs

Version 1.1.0

• New Features:

  • Internal class structure simplified

  • Scalar Arith methods (e.g. 2*X) for gpuMatrix/vclMatrix objects

  • Unary '-' operator (i.e. -X) for gpuMatrix/vclMatrix objects

  • Slice methods to point to gpuVector/vclVector subsets

  • Block methods to point to gpuMatrix/vclMatrix subsets

  • deepcopy method to explicitly copy object contents

  • 'log','log10', & 'exp' methods for vector objects

  • 'abs' method added for all objects

  • 'max' & 'min' method for all objects

  • 'cbind' & 'rbind' methods for gpuMatrix/vclMatrix objects

  • 'distance' method for pairwise distances

  • 'squared euclidean' distance added ('sqEuclidean')

  • 't' method added

• Features in Progress:

  • Additional matrix functions (QR-decompsition, SVD, Cholesky, solve)

  • 'device type' checks (i.e. deal with CPU & GPU objects), perhaps detect type from object?

Initial Release version 1.0.0
