Tīmatahia me te Intel® kotahi API kotahi API Raraunga Tatari Raraunga

Ko Intel® oneAPI Data Analytics Library (oneDAL) he whare pukapuka e awhina ana i te tere o te tātari raraunga nui ma te whakarato i nga poraka hangahanga algorithmic tino arotau mo nga s katoa.tagKo nga mahi tātari raraunga (te tukatuka o mua, te panoni, te tātari, te whakatauira, te whakamana, me te whakatau whakatau) i roto i nga momo mahinga, ipurangi, tohatoha tohatoha o te tatauranga. Mo nga korero whanui mo te oneDAL, tirohia te wharangi whaimana oneDAL.

I mua i to tiimata
oneDAL kei roto /Dal directory kei hea ko te whaiaronga i whakauruhia ai a Intel® oneAPI Base Toolkit.
Ko te putanga o naianei o oneDAL me te tautoko SYCL e waatea ana mo nga punaha whakahaere 64-bit Linux* me Windows. Ka kitea nga whare pukapuka oneDAL i hangaia i te /dal/ /atete whaiaronga.
Ki te ako mo nga whakaritenga o te punaha me nga whakawhirinaki e hiahiatia ana hei hanga examples, tirohia te Nga Whakaritenga Pūnaha wharangi.

Whakamutunga-ki-mutunga Example
Kei raro ka kitea e koe he rerengamahi whakamahi angamaheni mo te oneDAL algorithm i runga i te GPU. Ko te exampKei te whakaratohia mo te Hangarite Wae Matua algorithm (PCA).

Ko nga taahiraa e whai ake nei e whakaatu ana me pehea:

• Pānuihia nga raraunga mai i CSV file
• Whakahaerehia nga mahi whakangungu me nga mahi whakatau mo PCA
• Te uru atu ki nga hua takawaenga i whiwhi i nga whakangungu stage

1. Whakauruhia te pane e whai ake nei e waatea ana nga whakapuakanga oneDAL katoa.
   
2. Waihangahia he rarangi SYCL* me te kaikowhiri taputapu e hiahiatia ana. I tenei keehi, ka whakamahia te kaiwhiri GPU:
   const auto queue = sycl::queue{ sycl::gpu_selector{} };
3. I te mea kei te oneapi::dal nga whakapuakanga katoa kei roto i te mokowāingoa oneapi::dal, kawemai nga whakapuakanga katoa mai i te mokowāingoa oneapi hei whakamahi i te dal hei utu mo te oneapi::dal mo te poto: whakamahi mokowāingoa oneapi;
4. Whakamahia te puna raraunga CSV ki te panui i nga raraunga mai i te CSV file ki te tepu:
   const auto raraunga = dal:: panui (Tira, dal::csv::puna raraunga{“data.csv”});
5. Waihangatia he whakamaarama PCA, whirihorahia ona tawhā, ka whakahaere i te algorithm whakangungu mo nga raraunga i utaina mai i te CSV.
   
6. Tāngia te haeira eigen i akohia:
   
7. Whakamahia te tauira kua whakangungua mo te whakatauki hei whakaiti i te rahinga o te raraunga:
   

Hanga me te Whakahaere Examples
Mahia nga mahi e whai ake nei hei hanga me te whakahaere exampe whakaatu ana i nga ahuatanga whakamahinga taketake o tetahi DAL me te tautoko SYCL. Haere ki /dal/ katahi ka whakarite i tetahi taiao penei i te whakaaturanga o muaampkei raro:

FAKATOKANGA Ko nga mea katoa kei raro nei ka tiimata me te # ka kiia he korero me kaua e whakahaere me te waehere.

1. Whakaritea te taiao e hiahiatia ana mo te DAL kotahi (taurangi penei i te CPATH, LIBRARY_PATH, me LD_LIBRARY_PATH):
   • I runga i te Linux, e rua nga huarahi hei whakarite i te taiao e hiahiatia ana: ma te tuhi vars.sh, ma te waahanga ranei files.
   • Te whakatu i tetahi taiao DAL ma te tuhi vars.sh Whakahaerehia te whakahau e whai ake nei:
   puna ./env/vars.sh
   • Te whakatu i tetahi taiao DAL ma te kōwae files
   Arawhiti1. kōwae: puna $MODULESHOME/infit/bash
   FAKATOKANGA Tirohia te tuhinga Taiao Module mo nga taipitopito.
   Whakarato2. kōwae me te ara ki te kōwae files whaiaronga: kōwae
   whakamahi ./module files
   Whakahaerehia te3.module:
   dal kawenga kōwae
   • Ki Windows, whakahaeretia te whakahau e whai ake nei:
   /env/vars.bat
2. Tārua ./examples/neap/dip ki te whaiaronga tuhi mena e tika ana (na te mea ka hangaia he wa poto files):
   cp r ./examples/oneapi/dpc ${WRITABLE_DIR}
3. Whakaritehia te taiao whakahiato mo Intel® kotahi API DPC++/C++ Compiler. Tirohia Tīmatahia me te Intel® oneAPI DPC++/C++ Compiler mo nga taipitopito.
4. Hanga me te whakahaere i te exampe whakaatu ana me pehea te whakamahi i tetahi DAL me te tautoko SYCL:
   FAKATOKANGA Me whai whakaaetanga tuhi koe ki to muaamples kōpaki ki te hanga examples, ka mahia nga whakaaetanga hei whakahaere. Ki te kore, me kape koe i te examples/oneapi/dpc me examples/ oneapi/data kōpaki ki te whaiaronga me nga whakaaetanga tika. Me pupuri enei kōpaki e rua ki te taumata whaiaronga kotahi e pa ana ki a raatau.
   • I runga i te Linux:
   • I Windows:
   
5. Hei kite i nga tawhā katoa e waatea ana mo te tikanga hanga, patohia te hanga i runga i te Linux*, i te wetewete ranei i runga i te Matapihi*.
   Ko te putanga example rua me te rangitaki files kua tuhia ki te whaiaronga _results.
   FAKATOKANGA Me whakahaere e koe te examples mai examples/oneapi/dpc kōpaki, ehara i te kōpaki _results. Te nuinga exampe hiahia ana nga raraunga ki te penapena i roto i te exampkōpaki les/oneapi/raraunga me te whai hononga hono mai i muaampkōpaki les/oneapi/dip.
   Ka taea e koe te hanga tawhito C++ exampkei roto examples/oneapi/cup kōpaki i roto i te ara rite.

Whakahiato me te hanga tono me te pkg-config
Ko te taputapu pkg-config he taputapu e whakamahia nuitia ana mo te hanga rorohiko me nga whakawhirinakitanga. Intel® kotahi API Raraunga Raraunga Raraunga whakarato files me te pug-config metadata mo te whakahiato me te hono i tetahi tono ki te whare pukapuka.

Whakaritehia te taiao
Hei whakamahi i te pug-config, hangahia te whare pukapuka katahi ka whakarite i te taiao ma te whakamahi i nga tuhinga vars.sh, vars.bat ranei:

• I runga i te Linux: puna ./env/vars.sh
• I Windows: /env/vars.bat

Kōwhirihia he raraunga meta file
Ko te metadata fileKa whakaratohia e te DAL kotahi anake te whirihoranga taputapu manaaki i runga i te 64-bit Linux, macOS, punaha whakahaere Windows ranei mo C++.
Kōwhirihia te metadata file i runga i tetahi aratau miro DAL me te tikanga hono ka whakamahia e koe:

kotahi DAL pug-config metadata files

Miro-kotahi (miro-kore)		Miro-maha (miro-a-roto)
Hononga pateko	dal-static-sequential-host	dal-static-threading-host
Hono hono	dal-dynamic-sequential-host	dal-dynamic-threading-host

Whakahiato he papatono ma te whakamahi i te peg-config
Hei whakahiato i te kaupapa test.cpp me tetahi DAL me te titi-whirihora, homai te ingoa o te DAL pug-config metadata kotahi file hei tawhā whakauru. Mo te example:

• I runga i te Linux, i te macOS ranei:
  ice test.cpp pug-config –flags –libs dal-dynamic-threading-host
• I Windows:
  mo /F “delimbs=,” %i i roto ('pug-config –flags –libs dal-dynamic-threading-host) mahi icl test.cpp %i
  He sampte waehere mo svm_two_class_thunder_dense_batch exampme te tautoko SYCL. Whakahaerehia nga mea e whai ake nei mai i te exampwhaiaronga les/oneapi/cpp:
• I runga i te Linux, i te macOS ranei:
  icc -I puna/ puna/svm/svm_two_class_thunder_dense_batch.cpp icc test.cpp pkg-config –cflags –libs dal-dynamic-threading-host
• I Windows:
  mo /F “delis=,” %i in ('peg-config –flags –libs dal-dynamic-threading-host) mahi kino -I puna/ ill svm_two_class_thunder_dense_batch.cpp %i
